Depsgraph: Fix broken copy-on-write draw after ownership changes

Need to build layer collections callbacks using proper CoW pointer.

Rename Scene macros back to their original _NEW less names

Farewell Scene->basact

Cleanup: Use full name for scene_layer in alembic

Cleanup: Use full name for scene_layer in blenloader

Cleanup: Use full name for scene_layer in depsgraph

Cleanup: Use full name for scene_layer in draw

Cleanup: Use full name for scene_layer in gpu

Cleanup: Use full name for scene_layer in makesrna

Cleanup: Use full name for scene_layer in nodes

Cleanup: Use full name for scene_layer in python

Cleanup: Use full name for scene_layer in render

Cleanup: Use full name for scene_layer in windowmanager

Remove unused screen-name storage in window

Checked in really old revisions, seems like this was never used. So
doesn't matter for compatibility either (tested opening files saved with
this in 2.49).

Fix crash using pre 2.5 file as startup.blend

Cleanup: Refactor window matching after file read for readability

Code should hopefully be much clearer now.

Also removing code that's been commented out for a while, and was never
executed in master.

Moved alignment attributes from my last commit to BLI_compiler_attrs.h for future use.

Object.layers no longer around, removing from ui

Compositor: Ensured 16 byte alignment for variables accessed by SSE instructions.

Before this patch, the XBlur/YBlur compositor nodes would crash for me when run in a MSVC 2015 debug build (test scene: BMW27_cpu). I added the compiler instructions to explicitly align the local variables that the SSE instructions are accessing.

Depsgraph: Pass CoW pointer to ID datablocks evaluation functions

The only remaining part is the particle stuff, which needs a pointer to exact
particle system which does not exist yet. Leaving it for later a bit for until
it's more clear what do we do with particles.

Unless i'm mistaken, we've got all proper CoW pointers bound now.
