Primary goal of this commit is to fix an annoying issue - when processing and saving .blend
files in background mode you lose their thumbnails, since it can only be generated with
an OpenGL context.
Solution to that is to read .blend thumbnail while reading .blend file (only done in background
mode currently), and store it in Main struct.
Also, this lead to removing .blend file reading code from thumb_blend (no need to have doublons).
We now have a small interface in regular reading code area, which keeps it reasonbaly light
by only reading/parsing header info, and first few BHead blocks.
This makes code reading .blend thumbnail about 3 to 4 times slower than previous highly specialized
one in blend_thumb.c, but overall thumbnail generation of a big .blend files folder only grows
of about 1%, think we can bare with it.
Finally, since thumbnail is now optionally stored in Main struct, it makes it easy to allow user
to define their own custom one (instead of auto-generated one). RNA API for this was not added though,
accessing that kind of .blend meta-data has to be rethought a bit on a bigger level first.

- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
Flush edits only when saving global undo. This will stop freeing of PBVH
in sculpt mode, which introduces some pretty severe freezes, especially
in dyntopo. For global undo we flush the contents of the global undo
buffer which does not include localized edits of sculpt/edit mode, so
those data will not get saved anyway.

Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

Issue is that world shader compilation and loading may take long so we
just draw file previews with premultiplied background. Should create the
old familiar transparent background files.
Thanks to Sergey for figuring out the issue.
This reverts commit fbc2909cef.
The reason for revert is that the commit made it so bpy.data is not set to any
of the new main (on both file open and file link/append) which basically totally
broke versioning code.
Needs some smarter solution there.
This way addons and render engines which needs to do versioning code on files will properly
do it when something is being linked or appended to the scene. Previously that callback was
only called for the local main only, making it impossible to do tweaks on linking.
This time, it's a dedicated operator user has to run before saving the file.
And it recursively check all IDs linked from each scene, therefore rendering
materials etc. previews using a scene they are used in.
Note the renderengine issue is not completely addressed this way
(existing code for icon previews seems to ignore completely other engines,
and IDs not linked anywhere (fake-user ones) will be rendered with current scene's engine
as fallback, also you can get a material linked to an hidden object in a scene, etc.).

Sorry about that, should have checked this stuff more, with Internal material
renders are very fast (unoticable), but with Cycles it can take (a lot of) time,
like several minutes or more.
Will probably fall back to a dedicated operator users will have to fire themselves
when they want previews in their files.
After double checking the sequencer code, there doesn't seem to be any reason to
exclude these from the sequencer previews. This makes it possible to use the
sequencer to non-destructively chain together difference Grease Pencil animated
shots together without having to render each image sequence first, allowing for
a smoother workflow.
Just in case the initial assumption isn't entirely correct, I've put in place
an extra arg to the relevant functions which can be hooked up to a suitable
option on the scene strip later to turn this on/off as needed.
The issue here is that if no matching winid is found, we destroy all
windows and their context with them. This will also delete the OpenGL
textures associated with the initial context, thus we lose the icons.
This patch makes sure a window is always kept for later so the initial
context does not get lost.
Thanks to Campbell and Ton for the discussion on the issue.
The issue was caused by the changed defaults from the Cycles side.
Because of those properties being saved as an IDProp and not being
saved to the file, every change to the defaults would ruin someone's
day updating the values.
Added a bpy.app.handler.version_update which is run after the regular
do_versions() are done and could be sued by the scripts to apply
versioning code on their settings.

Rename UI_init_userdef_factory to BLO_update_defaults_userpref_blend
This closely matches BLO_update_defaults_startup_blend so makes sense for them to be together.
Current temporary data of Blender suffers one major issue - default 'temp' dir on Windows is never
automatically cleaned up, and can end being quite big when used by Blender, especially when we have
to store per-process data (using getpid() in file names).
To address this, this patch:
* Divides tempdir paths in two, one for 'base' temp dir (the same as previous unique tempdir path),
the other is a mkdtemp-generated sub-dir, specific to each Blender instance.
* Only uses base tempdir when we need some shallow persistance accross Blender sessions - and we always
reuse the same filename (quit.blend...) or generate small file (crash reports...).
* Uses temp sub-dir for heavy files like pointcache or renderEXRs (Save Buffer option).
* Erases temp sub-dir on quit or crash.
To get this working it also adds a working 'recursive delete' to BLI_delete() under Windows.
Note that, as in current code, the 'recover render result' hack-feature that was possible
with SaveBuffer option is still removed. A real renderresult cache feature will be added
soon, though.

There is not much sense to have a whole BLI file just to check SSE2 on CPUs...
So idea is to rename it to more generic "BLI_system", and add to it more system-related
utils, like e.g. an include helper for getpid(), which allows to hide unix/windows
internals from rest of the code...
