USD importer: normals count bounds check.

Added bounds check for vertex varying normals, to
prevent crashes reading badly formed meshes, where
the number of normals doesn't match the number
of points. Also guarding against null mesh.

Fixed memory block free error

Merge branch 'master' into soc-2021-vse-strip-thumbnails

Knife: Fixed undo deleting last vertex every time

Undo was deleting the first vertex of the last cut segment every time.
Now it only deletes it if the vertex has no other edges touching it.

Sculpt dyntopo: another attempt to fix undo memory corruption bug

Merge branch 'master' into temp-gpencil-bezier-stroke-type

Merge branch 'master' into asset-greasepencil

Merge branch 'master' into greasepencil-object

adaptive_cloth: fix: Mesh: split_edge_triangulate() crash when edges are realloced

Took the new edge index by reference instead of copy leading to wrong memory access when the edges are reallocated by the arena.

Merge branch 'master' into soc-2021-knife-tools

Knife: Added undo functionality

Pressing ctrl-z will now undo the most recent cut segment made.
When drag cutting undo reverts each segment of the cut individually.
Currently this breaks visible distance and angle measurements after using undo but a fix will be committed soon.

adaptive_cloth: Mesh: make split_edge_triangulate() work with new deletion methods

adaptive_cloth: Mesh: delink face edges

adaptive_cloth: Mesh: const get checked elements

Fix implicit int error

Remove extraneous code

Merge branch 'master' into temp_bmesh_multires

Sculpt dyntopo: Exposed UV smooth bruth in experimental features prefs.

* Also got undo working for it

adaptive_cloth: Mesh: better deletion of the elements

This new way of deleting elements ensures that no links can be missed out on. The deletion of the elements has to happen in a certain order leading to lesser number of errors.

This is API breaking, so all functions refering to deletion of the elements have to be updated. This includes, Mesh::split_edge_triangulate() and Mesh::collapse_edge_triangulate().
