Fix T63775: Toolbar icons ignore BLENDER_SYSTEM_DATAFILES

The environment variable to locate system data-files was
ignored by toolbar icons.

Add bpy.utils.system_resource
to match Blender's internal data-file access.

Cloth: collapse edges debugging statements

Fix T67389: Transform constraints fail at large distances

Fix T67040: Undo crashes after renaming

Correct fix that doesn't cause T67217.

Temporarily removing the excluded undo step broke memfile-undo
since freeing the undo steps needs to access other steps in
the list to merge shared chunks, see: memfile_undosys_step_free.

Pass the exclude step as an argument instead.

Merge branch 'master' into soc-2019-bevel-profiles

Bevel Operator: First pass at custom profile functionality in 'pipe' vertex mesh
case with two nearly parallel incident beveled edges. This attempts to reuse the
profile at each vertex in the mesh by intersecting the original profile with a new
plane at the current vertex's ring in the vmesh.

It currently works, but only for a portion of the vertices in the vmesh, which
suggests problems with the vmesh NewVert indexing

Profile Widget RNA API: Added new evaluation function to return 2D location
along the profile after travelling a specific portion of its length.

Small cleanup in Modifier RNA File: RNA definitions condensed

Add --debug-xr-time command line option for VR frame time info prints

Outputs frame render time in milliseconds and FPS this time would add up
to. We could average times so FPS is a bit more stable, but the
precision of un-averaged results may be helpful too.

Merge branch 'master' into filebrowser_redesign

Merge branch 'master' into soc-2019-openxr

Cleanup: Remove Printf

Merge branch 'tmp-batch-cache-cleanup' of git.blender.org:blender into tmp-batch-cache-cleanup

Mesh Batch Cache: Fix some threadsafety issue with indices buffers

Correct icons and text off center by few pixels

Mesh Batch Cache: Fix some threadsafety issue with indices buffers

Use base 10 for file size strings (MB, KB, ... instead of MiB, KiB, ...)

Make the column header interactive

Clicking on the column header will sort the file list based on the
clicked column. Note that sorting by time only is not supported, sorting
by date already sorts by time and date.

Cloth: fix bug in collapse edges

When the face is not collapsed, it needs to be removed from the active faces. To prevent a crash, doing a double i-- helps it only get faces which are within the size() and not capacity().

Cleanup: Use struct to wrap details column data

Also, related cleanup.
