add options to ignore subdivision, use prefetching, and disable caching

fix missing prefetching for subdivision meshes

Merge branch 'master' into temp-gpencil-io

Conflicts:
source/blender/python/intern/bpy_app_build_options.c

Allows deltas whose magnitudes are greater that 1.0.

Fix crashes caused by reading non-existent data

The index_data_map was not swaped with the rest of the data, and there
was no indication that the first frame does no have min/max data for the
delta range.

USD Import: uv fixes.

Added logic to handle the case where the st primvar
is a float2 array. Simplified the conditionals for
readability. Now only considering UVs when checking
for animating primvars.

USD IO: Merging latest importer code.

USD Export: format fixes.

USD Export: code cleanup.

Moved shader node functions out of usd_util.(h|cc), since
these files will be removed. However, the appropriate
place for these functions is yet to be determined and
should be considered further, since this is duplicate
code of currently inaccessible functions in other files.

USD Export: Code cleanup.

Moved usd_define_or_over() to usd_writer_matrial.h, since
util.h will be removed.

* Added a new CustomData type for dyntopo vertex data: MDynTopoVert.
It stores:
- Original coordiates, colors and mask (which were previously four
seperate layers).
- A bitmask with (currently) one bitflag, whether or not a vertex is
on a boundary.

I needed to cache calculating vertex boundary state (which involves
iterating over the edges surrounding a vertex) and got fed up with
having so many CD layers for dyntopo. This struct consolidates them
and saves having yet another layer just to store a flag.

Fix crash when showing empty shape-keys list

GPencil: Simplify fixed for bezier strokes

Python API: Expose CurveProfile Reset View function

Allow python access to the `reset_view` functionality which before
was only available through the menu. This was suggested for
consistency after D10561.

BLI: Add location, rotation, scale constructor to float4x4

This is simply a convenience when using this type. More similar
constructors can be added in the future when they are useful.

Cleanup: minor changes to pose-mode apply visual transform

- Remove use of evaluated poses, instead calculate transformations
into an array which is applied afterwards.

- Only update ID's for poses that have been changed.

Cleanup: remove unused function
