Sergey Sharybin 4228463caa Update Ceres to 1.7.0 release 
For Blender this release is interesting because of:

- Covariance estimation (not used in Blender yet, but now we
  might use it for keyframe selection instead of havingown
  implementation).

- Significant performance improvements to loss function and
  dense linear solvers and automatic differentiation.

  Unfortunately, didn't notice speedup of tracking itself,
  but camera reconstruction now happens around 2 times faster
  on my laptop,

- Better inner iteration step acceptance and stopping.

ITERATIVE_SCHUR works with no f-blocks.
When the Schur complement is of size zero,
i.e. none of the parameter blocks interact
with each other, the ITERATIVE_SCHUR linear
solver crashes due to some checks that are
triggered in the SCHUR_JACOBI preconditioner.
This patch adds logic to detect this condition
and to deal with it and adds tests that verify
the fix.
Thanks to Soohyun Bae for reporting this bug.

Cmake refactoring
1. Use CMake FindLAPACK and FindBLAS Modules.
2. Remove SEARCH_HEADERS and SEARCH_LIBS and replace them with
CMAKE variables. This leads to simplification of the FIND_LIBRARY
and FIND_PATH calls.
3. Make miniglog a fallback when glog is not present and the
user indicates MINIGLOG=OFF.
4. Add time.h to miniglog.
5. Remove shared library building.

Fix how Ceres calls CAMD.
CAMD requires that the id of the largest numbered elimination
group be less than the number of columns in the matrix.
This patch ensures that this is the case. Without this,
in certain cases its possible for CAMD to silently fail
while doing out of bounds access and then causing Ceres to fail.
Also add some logging about the problem size before and after
the reduced program has been created.

commit e45db9d05aaa26b1ddffa44c9190a1018aa2655f
Author: Sameer Agarwal <sameeragarwal@google.com>

Improve inner iteration step acceptance.
Normally, in a trust region algorithm the quality of a trust region step
is measured by the ratio
nonlinear_cost_change
r = ---------------------
model_cost_change
All the change in the nonlinear objective is due to the trust region step
so this ratio is a good measure of the quality of the trust region radius.
However, when inner iterations are being used, nonlinear_cost_change
includes the contribution of the inner iterations and its not fair to
credit it all to the trust region algorithm. So we change the ratio to be
nonlinear_cost_change
r = ------------------------------------------------
(model_cost_change + inner_iteration_cost_change)
In most cases this is fine, but it can be the case that the
change in solution quality due to inner iterations is so large
and the trust region step is so bad, that this ratio can become
quite small.
This can cause the trust region loop to reject this step.
This change, fixes this problem by looking at the inner_iteration_cost_change
explicitly and accepting a step if the inner iterations led to a net
decrease in the objective function value.
Along the way it also fixes the way model_cost_change is computed.
Changing to a more numerically robust way of computing it.
The last and final change is to ensure that inner iterations and the
non-monotonic version of the trust region algorithm interact correctly.
This addresses part 2 of
https://code.google.com/p/ceres-solver/issues/detail?id=115
As an illustration of the change.

Reduce memory usage in covariance estimation.
When using the SPARSE_QR algorithm, now a Q-less
factorization is used. This results in significantly
less memory usage.
The inversion of the semi-normal equations is now
threaded using openmp. Indeed if one has SuiteSparse
compiled with TBB, then both the factorization
and the inversion are completely threaded.

Move most of suitesparse/cxsparse ifdef code to their headers
Main purpose of this is to make implementation files free from
endless ifdef blocks every time this libraries are needed to be
included. This would hopefully prevent compilation errors in
the future caused by missing ifdef around header include.
This also includes some stubs added to suitesparse/cxsparse
headers to make code even more free from ifdefs.

Multiple dense linear algebra backends.
1. When a LAPACK implementation is present, then
DENSE_QR, DENSE_NORMAL_CHOLESKY and DENSE_SCHUR
can use it for doing dense linear algebra operations.
2. The user can switch dense linear algebra libraries
by setting Solver::Options::dense_linear_algebra_library_type.
3. Solver::Options::sparse_linear_algebra_library is now
Solver::Options::sparse_linear_algebra_library_type to be consistent
with all the other enums in Solver::Options.
4. Updated documentation as well as Solver::Summary::FullReport
to reflect these changes.

Use more performant, less conservative Eigen solvers.
colPivHouseholderQR -> householderQR
ldlt -> llt.
The resulting performance differences are significant enough
to justify switching.
LAPACK's dgels routine used for solving linear least squares
problems does not use pivoting either.
Similarly, we are not actually using the fact that the matrix
being factorized can be indefinite when using LDLT factorization, so
its not clear that the performance hit is worth it.
These two changes result in Eigen being able to use blocking
algorithms, which for Cholesky factorization, brings the performance
closer to hardware optimized LAPACK. Similarly for dense QR
factorization, on intel there is a 2x speedup.

Check GCC Version before adding -fast compiler option on OSX.
-fast compiler option is only supported using Apple's GCC packaged with XCode.
Other GCC versions will fail when this flag is enabled. This commit checks the
GCC version on OSX and only enables this flag when < 4.3. Apple's GCC is
currently 4.2.1 and a user is unlikely to install a non-apple version this old

Fix build breakage on old versions of SuiteSparse.
SuiteSparse_long is only defined in recent versions of SuiteSparse
as the index variable type for large matrices. In older versions
UF_long was used. Ubuntu still ships with an older version of
SuiteSparse, so an ifdef is needed to fix the build.
This patch has been tested on mac and on linux with older and
newer versions of SuiteSparse.

Use ATLAS as the example BLAS in building.rst
OpenBLAS has subtle issues releated to threading. It
conflicts with the use of threads in the other parts of
the application.
Careful users can still use it by disabling threads via
an environment variable, but by default we want to use
a BLAS/LAPACK that does not suffer from these problems.

More CMake file cleanup.
Reduce the verbosity of the Cmake file. All the "Checking for"
messages have been removed since we log both success and failures.
Further, UFConfig is only searched for if SuiteSparse_config cannot
be found.

Extend the C API to support loss functions
This extends the C API to support loss functions. Both
user-supplied cost functions as well as the stock Ceres cost
functions (Cauchy, Huber, etc) are supported. In addition, this
adds a simple unit test for the C API.
Supporting loss functions required changing the signature of the
ceres_add_residual_block() function to also take a thunk for the
loss function.

Rationalize some of the variable names in Solver::Options.
lm_max_diagonal -> max_lm_diagonal
lm_min_diagonal -> min_lm_diagonal
linear_solver_max_num_iterations -> max_linear_solver_iterations
linear_solver_min_num_iterations -> min_linear_solver_iterations
This follows the pattern for the other parameters in Solver::Options
where, the max/min is the first word followed by the name of the
parameter.

Fix update of L-BFGS history buffers after they become full.
Previously there was an assignment dimension mismatch in the
history update; thus, over time, the history would contain
(only) replicated copies of the (max_num_corrections_ -1)-th
update and the most recent update.
