New dependency graph puts materials to the graph in order to deal with animation
assigned to them and things like that. This leads us to a requirement to update
relations when slots changes.
This fixes: T49075 Assignment of a keyframed material using the frame_change_pre handler
doesn't update the keyframe using the new dependency graph
All in all, this patch adds an Alembic importer, an Alembic exporter,
and a new CacheFile data block which, for now, wraps around an Alembic
archive. This data block is made available through a new modifier ("Mesh
Sequence Cache") as well as a new constraint ("Transform Cache") to
somewhat properly support respectively geometric and transformation data
streaming from alembic caches.
A more in-depth documentation is to be found on the wiki, as well as a
guide to compile alembic: https://wiki.blender.org/index.php/

Many thanks to everyone involved in this little project, and huge shout
out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini
and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the
custom builds and compile fixes.

Initial report/patch by Alexander Gavrilov (@angavrilov), found more on the road.
Nice demo of why we should use libquery ID looper in read code too - but that's for another day
(also because read code needs to take care of some deprecated pointers sometimes)...
The flatten brush depended on accumulate being disabled,
Adding dynotopo support for accumulate caused problems for this tool (see T44390).
Enable for existing files.
- icon_id from ID and PreviewImage were not guaranteed to be in sync.
- PreviewImage one was not reset on file read.
- Through RNA e.g., it was possible to ensure an ID icon via its preview image,
which was running code designed for custom previews/icons system, instead
of generating correct 'auto ID icon'.
`my_memcmp` didn't work properly comparing memory sizes not aligned to 4 bytes,
this worked while we used guarded-alloc (which always wrote a guard at the end of each allocation).
Since moving to lockfree allocator it could read uninitialized memory.
It also consistently performed ~10-30% worse then glibc's.
This is typically well optimized, no need to do ourselves.
This breaks any post-versionning (like IPO conversion, python handler, etc.).
rB961ebfa8c40b9909 mentions some Main being do_versionned several times (which is not desired for sure),
will try to reproduce again and find another fix.
Since SDNA was allocated for each undo step,
the new address meant it was considered different and included again.
Add an option not to duplicate the DNA string when calling DNA_sdna_from_data,
as well as avoiding a redundant copy, it writes the same address each time.
Environment lighting (aka ambient) is a key component of any renderer.
It's implemented like the Environment lighting of BI render for Approximate Gather mode. It support "Sky Color" and "White" Environment lighting modes.
It would be great if the user could see actual lighting conditions right in the Blender viewport instead of waiting for the renderer to complete the final image, exporting for external renderer or for a game engine.

This commit adds operators and Outliner menu entries to reload or relocate a library,
and to delete or replace a datablock.
RNA ID API is also extended to allow ID deletion and remapping from python.

Some area were still not in sync with readfile.c, now should be better.
Note that readfile.c has been used as référence here re us refcounting,
not sure how accurate it is, time will say :|
