Sergey Sharybin caa2306d16 Libmv: Update to latest upstream version 
Main purpose of this is to bring new gflags library which is more likely
to have a fix for undefined order of static variables initialization and
also to bring new glog where some compilation error are fixed (which are
only visible with more strict checks with clang and c++11 enabled).

Update GFlags to latest release 2.1.1
Main purpose of this (andsome of upcoming) update is to check if the
upstream sources are useable without any modifications for us. And if
not, then we'll need to consider moving some changes into upstream.
This commit contains an one-to-one copy of the upstream GFlags library
and also changes namespace usage since it's changed in the upstream.

Libmv: Support disabled color channels in tracking settings
This was never ported to a new tracking pipeline and now it's done using
FrameAccessor::Transform routines. Quite striaghtforward, but i've changed
order of grayscale conversion in blender side with call of transform callback.
This way it's much easier to perform rescaling in libmv side.

implement backward prediction
The title actually says it all, just extend current implementation
of PredictMarkerPosition() to cases when tracking happens in the reverse
order (from the end frame to start).
it's still doesn't solve all the ambiguity happening in the function
in cases when one tracks the feature and then re-tracks it in order
to refine the sliding. This is considered a separate TODO for now and
will likely be solved by passing tracking direction to the prediction
function.

Fix search area sliding issue
The only way to do this is to store search region in floats
and round when we need to sample it. Otherwise you'll always
have sliding effect caused by rounding the issues, especially
when doing incremental offset (thing which happens in the
prediction code).
Pretty much straightforward change apart from stuff to be kept
in mind: offset calculation int should happen relative to the
rounded search region. This is because tracker works in the space
of the search window image which get's rounded on the frame access,
This makes API a bit creepy because frame accessor uses the same
Region struct as the search window in Marker and ideally we would
need to have either IntRegion or Region<int> in order to make
Libmv fully track on what's getting rounded and when.

Support multiple distortion models, including a new division model
This commit makes it so CameraIntrinsics is no longer hardcoded
to use the traditional polynomial radial distortion model. Currently
the distortion code has generic logic which is shared between
different distortion models, but had no other models until now.
This moves everything specific to the polynomial radial distortion
to a subclass PolynomialDistortionCameraIntrinsics(), and adds a
new division distortion model suitable for cameras such as the
GoPro which have much stronger distortion due to their fisheye lens.
This also cleans up the internal API of CameraIntrinsics to make
it easier to understand and reduces old C-style code.

Fix failure of the image transform linear test
Mainly was caused by the flakyness of image rotation in cases
when image has even size. The test was expecting the transform
code to rotate the image around pixel corner, which isn't a
common behavior in image processing applications. Rotation
is usually done around the pixel center.
So now made it so RotateImage() rotates the image around the
pixel center which gives 100% proper result for odd sized images
(i.e. center pixel stays untouched).
Also made the tests to use odd image sizes which are more
predictable by the humans. We can use even sized images in the
tests as well but their result wouldn't be so much spectacular.
Another issue with the tests was caused by RescaleImageTranslation
test which did expect things which are not happening in the
function.
