Cleanup: USD: remove unused header files

Undo: Re-use existing IDs from old bmain: do not search by name.

This is actually a fairly bad idea, since IDs can be renamed...

Only search by pointer value now, this *should* work in all expected
cases once undo/redo fully reuses unchanged data-blocks.

Undo: save/restore DEG closer to the actual undostep.

Archive build script: stop when creating archive fails

The `subprocess.call()` function doesn't check the exit status code of the
subprocess. Use `subprocess.check_call()` or `subprocess.run()` instead.

Archive build script: fix compatibility with older tar on CentOS 7

On CentOS 7, `tar --use-compress-program='xz -9'` tries to run `xz -9` as
executable, rather than running `xz` with `-9` as argument. Passing the
`-9` option via the `XZ_OPT` environment variable, as suggested by
@campbellbarton in D6138, works fine.

Revert "Fully WIP code."

GPencil: Add missing Overlay mode

The VERTEX mode was not checked in shaders and must be managed equals to MATERIAL mode.

EEVEE: Cleanup

Remove redundant defines.

UI: use popover for NDOF menu

Number sliders were being used in a menu which doesn't work very well.

This was too slow taking around 8 seconds for a full revolution.

3D View: fix NDOF rotation around object locking pan

Cleanup: comments, redundant normalize

CMake: Remove stray WITH_JACK in blender_release.cmake

Missed one in the previous commit.

CMake: Remove stray WITH_JACK in full configuration

GPencil: Implement Vertex Overlay and set Vertex as default

Now in Material Overlay mode the Vertex Color is not used and by default the 2D template uses Vertex Mode

GPencil: Make Vertex Color works in Vertex Mode

WIP: Need to disable Vertex Color in Material mode
