Cleanup from review comments.

Fix normal prop read/write scope.

Merge branch 'master' into id-remap

Fix crash accessing non-existing property.

Fix crashing accessing normals out-of-bounds.

Normals in Alembic can either be per-face or per-vertex, so read the
normals according to their scope. Face normals are not read at the
moment since I couldn't figure out how to read the data and there are
some other annoying crashes that need to be fixed beforehand.

Third attempt, too stupid to add new files. (D2002).

Revert "And again, after Windows compile fix..."

This reverts commit f36a7b8ca4e9d006136370d69da177eee7f61c72.

And again, after Windows compile fix...

Merge remote-tracking branch 'origin/master' into experimental-build

Handle job cancelation.

Cancelling an export will remove the exported abc file from disk.

Cancelling an import will simply stop reading/processing the data, still
needs to remove created objects from the scene.

Revert "Apply D2002 for testing purposes (Cycles Multiscatter GGX)"

This reverts commit 375f2bda79e25cfb259d56778270bc82ffe966f6.

Revert "Decklink test for OSX"

This reverts commit 3b0070665241386fa0c0ab0ef401da604ac3a1b8.

Fix constraint not working with relative paths.

Some improvement to custom data reading:

- split custom data reading from AbcMeshReader
- Only add UVs to meshes if the ISchema has some, use proper UV name for
the {I|O}Schema.
- Fix crash reading mcols from other software.

Cleanup: headers

Move remapping functions into BKE_library_remap.h

This is done since remapping is quite an involved process.
