BLI_math: add mat3_normalized_to_* functions
...
Many uses of matrices for rotation keep them normalized,
so no need to normalize each time.

BLI_math: add invert_qt_normalized
...

(just conjugate_qt which asserts on non unit quats).

Fix T46521: Python: bvh.ray_cast doesn't find a plane facing in the other direction under certain circumstances
...
The issue was caused by wrong sign check. It originally came from more optimized
Cycles code where because of other reasons it wasn't visible yet. But in fact it
should be solved there as well.

to enforce that behvior on users here.
To be backported to 'a' release.

BLI_math: add mat3_polar_decompose, interp_m3_m3m3 and interp_m4_m4m4.
...
mat3_polar_decompose gives the right polar decomposition of given matrix,
as a pair (U, P) of matrices.
interp_m3_m3m3 uses that polar decomposition to perform a correct matrix interpolation,
even with non-uniformly scaled ones (where blend_m3_m3m3 would fail).
interp_m4_m4m4 just adds translation interpolation to the _m3 variant.

Fix (unreported) broken export of timecodes in SubRip VSE exporter.

Would write 1.04 seconds as `00:00:01,40` instead of `00:00:01,040`...
Anyway, we already have BLI API for timecodes, much better to add
SubRip timecode format there, heavily simplifies code.
To be backported to final 2.76.

Fix T45389 Windows thumbnails not working.
...
Also they did not work when using blender -R from
command line in 64-bit systems.
Issue was checking for wrong define which would
cause code to detect if the blender executable
functions under 32 bit emulation.
For 64bit executables this is false, leading
blender to believe we are operating under a 32bit
system, and registration would try to register
the 32bit thumbnailer.
This 32 bit dll is (correctly) missing for local
installs and from the new installer, thus no thumbnails.
