Usual i18n messages fixes...

Fix T45424: Blender able to create folders with invalid characters at the end of the name.

In fact, filebrowser was not making any checks for invalid file/dir names here!

Added checks in the three places that should be protected:
* Renaming.
* Creating dirs.
* Typing in filename field.

BLI_path_utils: fix/enhance BLI_filename_make_safe(), add BLI_path_make_safe().

BLI_filename_make_safe had several issues:
* Would replace all dots ('.'), not a great idea since it would break extensions.
* Was not checking for 'control' ASCII chars (though unlikely, better to be safe here).
* Win32 only: was not checking for forbidden names (con, aux, ltp0, com0, etc.).

New BLI_path_make_safe() simply checks each path's item with BLI_filename_make_safe().

BLI_fileops: Make BLI_dir_create_recursive() return success/error status.

Handy to know directly whether a file creation succeeded or not.

Also, made a few more changes in this func, and harmonized a bit win32/*nix versions.

Particle Info node support for GLSL mode and the internal render.

Display optimizations part 1.

This patch changes the way we draw meshes by introducing
indexed drawing. This makes it possible to easily
upload and rearrange faces ad lib according to any criteria.

Currently we use material sorting but textured sorting and
hiding will be added to optimize textured drawing and skip
per face testing.

It also adds support for vertex buffers for subsurf
modifiers (Except from GLSL drawing), making drawing of
subsurf much faster without need for bogus modifiers.

Tests show that we gain approximately 20-25% performance
by that for solid mode drawing with up to 50% gains for
material drawing. Textured drawing should also have a
small performance gain, but more substantial optimizations
are possible there.

Move from MTFace to MTexPoly w/ texture checks

Part of moving away from MFace.

Cleanup: headers (wm)

Fix for recent optimization commit in endian switch

Pre-4.8 GCC had a bug which lead to non-exposed __builtin_bswap16() symbol.

Fix T45423: depsgraph: crash in IDDepsNode::tag_update

Two issues fixed in this commit:

- Clearing or adding animation via python should ensure relations are valid.
- Animation component animation data might be null caused by removing animation
from python.

Make tooltip parsable by human compilers (thanks to Pablo for
suggestion)

Data Transfer: very minor cleanup...

Workaround for non-bleeding edge compilers and const cast of pointer arrays.

Cycles: Add logging to detected OpenCL platforms and devices

Happens on verbosity level 2, should help looking into some of the
bug reports in the tracker.

Cleanup: replace BLI_split_file_part w/ BLI_path_basename

Cleanup: use ascii as suffix (as with utf8)

BKE_deform: assert on invalid args

Will phase these out eventually
