Assorted fixes for keyframe selection:
- Biggest error was in cost functors used for F and H refirement,
they were just wrong.
- Use natural logarithms, since it's actually makes sense from
math papers point of view and error is somewhere else.
- Disabled rho for GRIC, for now use non-clamped error for tests.
- Made SymmetricEpipolarDistance returning non-squared distance
Keyframe selection is currently the only used of this function
and it seems using non-squared distance makes much more sense.
Also would think to append suffix "Squared" to functions which
returns squared distances.
- Removed templated version of SymmetricEpipolarDistance, since
it's not needed actually.
This is actually even worse working than previous implementation,
but commit it needed for further review.

Euclidean resection cost function didn't use correct constructor
It was storing a reference to initial rotation passed by value,
leading to pointer being pointing to a stack variable, leading to
wrong memory access in residuals computing.
Apparently was visible in optimized builds only with inline
substitution allowed.

Automatic keyframe selection based on Pollefeys's criteria
This commit implements automatic keyframe selection algorithm
based on Pollefeys's criteria (F-GRIC is smaller than H-GRIC
and correspondence ratio is more then 90%).
It is implemented as a part of simple pipeline and returns
vector of keyframe images for a given Tracks structure.
For simple pipeline reconstruction two best keyframes are
expected to be selected from all detected candidates.
Criteria for this selection could be reprojection error of
solution from two candidate keyfames.
Unfortunately, it's not fully workable yet, hopefully would
be fixed soon.

Camera Tracking: allow fallback to reprojection resection
by user demand
This fixes some "regressions" introduced in previous commit
which lead to much worse solution in some cases. Now it's
possible to bring old behavior back.
Perhaps it's more like temporal solution for time being smarter
solution is found. But finding such a solution isn't so fast,
so let's bring manual control over reprojection usage.
But anyway, imo it's now nice to have a structure which could
be used to pass different settings to the solver.

Make Euclidean resection "always" succeed.
The Euclidean resection code had a magical constant, 1e-3, used to
compare the results of solving an equation. This failure detection
was well-intended, trying to prevent poor solutions from getting
made without notifying the caller. Unfortunately in practice, this
threshold is too conservative. Furthermore, it is not clear the
threshold should exist at all; the purpose of the Euclidean
resection is to come up with the best solution it can; other
methods (e.g. reprojection error) should be used to compare
whether the method succeeded.
This commit changes the Euclidean EPnP code to always succeed,
causing the previous fallback to projective resection to never
run. In most cases, this will result in better reconstructions.
This should, in most cases, fix the dreaded "flipping" problem.

Add smarter tolerance checking in the planar tracker.
The planar tracker uses Ceres for the refinement stage. During
refinement, Ceres iteratively updates the parameters with the
latest best guess. If the change in the parameters falls below a
threshold, Ceres will abort successfully ("converged").
For the case of pure translation tracking, the parameters are
exactly the two pixel shifts (dx, dy), and measuring the change in
these parameters gives a meaningful termination criterion.
However, for all the other parameterizations like affine, where
the parameterization involves affine parameters that have no
physical interpretation, Ceres is left with no way to terminate
the solver early. With the existing code, often many iterations
are run long after Ceres has found a solution sufficiently
accurate for all tracking needs. No one needs tracking with
a quadrillionth of a pixel accuracy; that time is wasted.
This patch extends the existing iteration callback that is passed
in to Ceres to check if the pattern has fallen out of the search
window, to also check if the optimizer has made a tiny step. In
particular, if the maximum shift of any patch corner between two
successful optimizer steps is less than a threshold (currently
0.005 pixels), the track is declared successful and tracking
is terminated.
This leads to dramatic speed increases in some cases, with little
to no loss in track quality. This is especially apparent when
tracking patches with affine or perspective motion models. For
example, on some tracking cases I tried, the iterations Ceres took
went from 50 to 3.

Detect too-small planar tracking patches.
The planar tracker did not detect very skinny patches which have
effectively zero area and are untrackable. This adds detection and
rejection of patterns with zero area. This fixes a crash found by
during Mango production.

Fix crash when tracking in planar motion model (and maybe some other)
It was an Abort() caused by check for solver result not equal to USER_ABORT.
In some cases solver returns USER_ABORT due to BoundaryCheckingCallback
detects coordinates does not belong to image.
Somehow this callback wasn't called in previous version of Ceres and
in the same case marker was jumping. Now when the callback is called
it seems we could simply return failure of tracking without aborting
Blender.
Probably this is in fact some issue somewhere else, would double
check with Keir about this.

Add new warp regularization scheme for planar tracking.
This adds a new term to the tracking cost function that
restricts how much the optimizer can warp the patch (as
opposed to merely adjusting the translation). This should
reduce the "jumpiness" that is sometimes seen when doing
non-"Loc" tracks.
It is disabled in this commit; a subsequent commit will add
controls to the tracking dialog for this.

Planar tracker polish.
- Fixes the correlation checking code that was broken in the
previous commit. The bug was a transpose error.
- Fixes a memory leak of the warp functor, found by Sameer.
- Various cleanups done at Sameer's suggestion.
Thanks to Sameer Agarwal for a code review.

Make planar tracking much faster.
- This makes planar tracking around 2-3x or more faster than
before, by rearranging how the sampling is done.
Previously, the source patch was sampled repeatedly on
every optimizer iteration; this was done for
implementation speed, but was wasteful in computation.
- This also contains some additions to Ceres to help
deailing with mixed numeric / automatic differentation. In
particular, there is now a "Chain::Rule" operator that
facilitates calling a function that takes Jet arguments,
yet does numeric derivatives internally. This is used to
mix the numeric differentation of the images with the warp
parameters, passed as jets by Ceres to the warp functor.
There is also a new "JetOps" object for doing operations
on types which may or may not be jets, such as scaling
the derivative part only, or extracting the scalar part
of a jet.
This patche is aimed at Ceres upstream.
- A new function for sampling a patch is now part of the
track_region.h API; this will get used to make the preview
widget properly show what is getting tracked. Currently
the preview widget does not handle perspective tracks.
Known issues:
This patch introduces a bug such that the "Minimum
Correlation" flag does not work; if it is enabled, tracking
aborts immediately. The workaround for now is to disable the
correlation checking, and examine your tracks carefully. A
fix will get added shortly.

Support normalization in the tracking prepass
The last tracker commit added normalized tracking. This makes
tracking patches undergoing uniform illumination change easier.
However, the prepass which computes a quick translation-only
estimate of the warp did not take this into account. This commit
fixes that.
This works reasonably well but in some examples the brute
initialization fails. I suspect this is due to the warped template
estimate in the current frame being too different from the
original, so there are multiple peaks in the normalized-SAD
correlation function.
The solution is to use the previous frame for the brute
initialization and the keyframe for refinement, but that requires
architecture changes.

Add light-normalized tracking to the planar tracker
This commit adds the ability to normalize patterns by their
average value while tracking, to make them invariant to global
illumination changes.
To see this in action, check out the "Lobby" scene from Hollywood
VFX. If you track the markers that are shadowed by the actress,
previously they would not track. With the scale adaption on, the
tracker would shrink the area to compensate for the changed
illumination, losing the track. With "Normalize" turned on, the
patch is correctly tracked and scale is maintained.
A remaining problem is that only the Ceres cost function is
updated to handle the normalization. The brute translation search
does not take this into account. Perhaps "Prepass" (see below)
should get disabled if normalization is enabled until I fix the
prepass to normalize as well.
There are a few other changes:
- Bail out of the sampling loop early if the mask is zero; this
saves expensive samples of the image derivatives.
- Fix a bug where the mask was ignored when sampling in the cost
functor.

Add new planar tracker features and use the new planar API
This commit removes the use of the legacy RegionTracker API from
Blender, and replaces it with the new TrackRegion API. This also
adds several features to the planar tracker in libmv:
- Do a brute-force initialization of tracking similar to "Hybrid"
mode in the stable release, but using all floats. This is slower
but more accurate. It is still necessary to evaluate if the
performance loss is worth it. In particular, this change is
necessary to support high bit depth imagery.
- Add support for masks over the search window. This is a step
towards supporting user-defined tracker masks. The tracker masks
will make it easy for users to make a mask for e.g. a ball.
- Add Pearson product moment correlation coefficient checking (aka
"Correlation" in the UI. This causes tracking failure if the
tracked patch is not linearly related to the template.
- Add support for warping a few points in addition to the supplied
points. This is useful because the tracking code deliberately
does not expose the underlying warp representation. Instead,
warps are specified in an aparametric way via the correspondences.
- Remove the "num_samples_xy" concept and replace it with
automatic determination of the number of samples. This makes the
API easier for users.
- Fix various bugs in the parameterizations.
There remains a bug with subpixel precision tracking when in
"keyframe" mode; this will get fixed shortly.

"Efficient Second-order Minimization" for the planar tracker
This implements the "Efficient Second-order Minimization"
scheme, as supported by the existing translation tracker.
This increases the amount of per-iteration work, but
decreases the number of iterations required to converge and
also increases the size of the basin of attraction for the
optimization.

Add a planar tracking implementation to libmv
This adds a new planar tracking implementation to libmv. The
tracker is based on Ceres[1], the new nonlinear minimizer that
myself and Sameer released from Google as open source. Since
the motion model is more involved, the interface is
different than the RegionTracker interface used previously
in Blender.
The ESM tracker, also known as the KLT tracker in the UI, is
temporarily changed to use the new Ceres-based planar
tracker in translation-only mode. Currently it is a bit
slower than ESM and also doesn't have all the bells and
whistles implemented. Those will come soon. Longer term,
both trackers will remain since Ceres is unlikely to be as
fast as ESM for pure translation solving, due to its
generality.
The next step is to implement a new tracking UI. The current
UI assumes a translational motion model; the new one must
support arbitrary perspective transforms of the pattern
regions.

Initial Ceres integration
Currently only put sources to src/third_party/ceres and made sure they're
not giving compilation issues.
Used Ceres upstream version 1.3.0.
Needed to make some modifications to it's CMakeLists.txt also to glog and
fglags. They're described in README.libmv of this libraries.
Basically:
- Added -fPIC to glog/gflags, so shared ceres library could be linked
statically against this libraries.
- Tweaked Ceres's build rules to use needed libraries from libmv's
third_party folder.

Added solver for modal camera motion, currently supports only tripod solving
This solver is intended to deal with such camera motions as tripod and panning,
where it's impossible to reconstruct exact position of markers in 3d view.
It projects markers onto sphere and uses rigid registration of rotation to
find rotation angles which makes bundles from previous and current frame be
as closest as it's possible.

implementation of some basic algorithms for point cloud orientation:
- Implementation of rigid registration algorithm which searches transformation
form one point cloud to another assuming that points in this clouds are
already paired (points with the same index in different clouds belongs to
the same pair) which minimizes average distance between points in pairs.
Algorithm uses Levenberg-Marquardt solver to find such transformation.
Supports registration of rotation-scale-transform (which is probably most
common usage) and rotation only (which might be useful for basic modal
tripod solver).
- Implementation of Iterative-Point-Clouds algorithm which searches
transformation from one arbitrary point cloud to another making
points as closest to each other as possible.
This algorithm doesn't require points be initially paired, but for
good result clouds should have rough initial orientation. If they're
arbitrary oriented from the very beginning, algorithm might fail
producing good resold.
Iteration is based on building pairs of closest to each other points
and registering rigid transformation between them which incrementally
constructs final result.
TODO: building pairs might be speedup a lot using data structures like
AABB trees, K-D trees or so.

Trackers refactoring:
- Deduplicate pattern sampling used in esm and lmicklt trackers
and move SamplePattern to image/sample.h
- Move computation of Pearson product-moment correlation into
own function in new file image/correlation.h so all trackers
can use it to check final correlation.
- Remove SAD tracker. It's almost the same as brute tracker,
with only two differences:
1. It does brute search of affine transformation which in some cases
helps to track rotating features
2. It didn't use common tracker api which probably gave some speed
advantage, but lead to a real headache to use it together with
other trackers leading to duplicated code in 3d-party software.

Upgrade gflags and glog libraries - stage 2 (final)
Changes to upstream code which are needed to make libmv compile smooth on all platforms
* Replace <gflags/gflags.h> with "third_party/gflags/gflags/gflags.h" which is easier
to setup things in libmv and also helps with setting up building libmv into
external applications.
* Replace "glog/logging.h" and "glog/logging.h" with <glog/logging.h> and <glog/logging.h>
which is needed on Windows platform because otherwise files like logging.cc will be using
relative path which points to headers used by linux instead of headers need to be used
on Windows.
* Replace _asm int 3 with __debugbreak(). Such assembler code is obsolete and doesn't work
with 64bit versions of MSVC compilers.
* Do not use stacktrace for MinGW and FreeBSD because it leads into issues accessing
some specific data on this platforms.
* Define HAVE_LIB_GFLAGS for Windows builds.
* Do not define __declspec(dllimport) for MinGW platforms.
* Setup proper includes and datatypes for int32, uint32, int64 and uint64 for MinGW
* Do not define va_copy for MinGW platforms (it's already defined there).
* Patch localtime_r to be working fine with MinGW, disable strerror_r for MinGW because
of lack of needed functions.

Upgrade gflags and glog libraries - stage 1
This commit copies sources from latest original release of gflags and glog
over currently bundled versions of this libraries without any modifications.
This revision can't b compiled, all needed changes to make new libraries working
fine will be done with next commit to make it clear which changes were necessary
for easier bundling further newer version and extract patches and put them to
gflags/glog upstream repo.
Such upgrade of libraries is needed to make it able to compile libmv
with clang compilers. Currently used versions:
- gflags is version 2.0
- glog is version 0.3.2

SAD tracker now can deal with pattern size any size,
Very quick implementation came from Blender before Hybrid tracker was added.
Better to be replaced with brute tracker.
