Cleanup: Line-width

Merge branch 'master' into blender2.8

Alembic import: don't use global main

Alembic import: removed BaseLegacy from BKE_cachefile_clean

Now we just iterate over all objects. It may be a better idea to use a
smarter approach for performance. However, since this function is not
called regularly (only when changing Alembic file paths), it's not a very
big deal.

Draw Manager: clear draw global data after use

Draw Manager: store context vars per draw

Was performing context access per object for scene, region etc.
While not very slow they don't change during drawing so cache in a struct.

This also makes it possible to draw in views besides the current context.

Fix T51292: Alembic import, show notification when trying to load HDF5

HDF5 Alembic files are not officially supported by Blender. With this
commit, the HDF5 format is detected even when Blender is compiled without
HDF5 support, and the user is given an explanatory error message (rather
than the generic "Could not open Alembic archive for reading".

Cycles: Fix strict compiler flags

Fix OSX buildbot

Fix T51262: Blender CRASH with alembic file

Also added a unit test for exporting & importing very long names.

Cycles: Cleanup, mainly line length in random module

Was doing lots of investigation recently, with need to have lots of things
side by side.

Revert "Alembic: Construct ISampleSelector once and pass along"

This reverts commit 099816587a0e064fb6a52c82a737ae8814cf21df. It had some
unforseen side-effects that should be investigated first.

Cycles: Split vectorized math utilities to a dedicated files

This file was even a bigger mess than vectorized types header,
cleaning it up to make it easier to maintain this files and
extend further.

Cycles: Split vectorized types into separate files

The final goal to reach is to make vectorized types much easier to maintain
and the previous design had following issues:

- Having all types and methods implementation made the source file rather
bloated and unfun to navigate in.

- It was not possible to quickly glance available API for the type you are
interested in.

- Adding more vectorization types will bloat the file even more, making
things even more tricky to follow.

Cycles: Cleanup, preprocessor indentation

Fix T51284: Mesh not skinned

WM: don't search for app-template when its empty

Changing from a loaded app-template back to Default (none set)
would scan paths for a file with no name. Harmless but silly.

OpenGL: better context creation on Windows

Compatibility profile was working fine, this is mostly to get the highest GL core profile version available.

Our minimum requirement is 3.3 core profile. When we request a specific GL version:
- AMD and Intel give us exactly this version
- NVIDIA gives at least this version <-- desired behavior
so we ask for 4.5, 4.4 ... 3.3 in descending order to get the best version on the user's system.

Accept OpenGL 3.0 on Mesa instead of 3.3+ compatibility profile. (requested by @LazyDodo) This will be removed after we finish moving to core profile.

Part of T49012 and T51164

group WITH_LEGACY_OPENGL with the other GL options

Blender subsystems that care about OpenGL use GL_DEFINITIONS, which now includes the newest (temporary) WITH_LEGACY_OPENGL.

Also updated Gawain's CMake to use this instead of its own logic.

Cycles: Remove re-hashing done in BPT volume code

Since 9d50175 this is no longer needed, at least not with the current
sampler we are using.
