be72df4f06 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.

a5e631171b BLI_path api, minor changes to CWD handling 
- BLI_current_working_dir's return value must be checked, since it may fail.
- BLI_current_working_dir now behaves like getcwd, where a too-small target will return failure.
- avoid buffer overrun with BLI_path_cwd, by taking a maxlen arg.

c919ce3aa9 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.

7f63eaafd6 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.

c5018c65b9 BLI_fileops: Some fixes and cleanup. 
* Fix BLI_file_touch, used to add one dummy byte ((unsigned char)EOF) to empty files!
* Get rid of static global temp string in WIN32 area (very bad, and useless!).
* Get rid of paranoid NULL checks in WIN32's BLI_gzopen().
* Add non-relative filename asserts to WIN32 file operations too.
* ifdef-out BLI_move and BLI_create_symlink, unused (and the later is not even implemented for windows).

Partly based on patch and points raised by Jason Wilkins (jwilkins) in T32870, thanks!
