Fix weirdly appearing and disappearing compile error

OpenSubdiv: Cleanup of include directories

OpenSubdiv: Remove code responsible for topology creation from DM

It was moved to Blender side, no need to do bad level data access.

OpenSubdiv: Implement topology refiner converter from Blender side

This way it's possible to avoid having bad level calls to DM code from
intern/opensubdiv and also makes it possible to create topology refiner
from CCGSubSurf structure in the future.

Another alternative BVH Tree representation for totally custom user
geometry.

The new constructor method allows creating a BVHTree from a list of
vertices and triangles directly, without a separate mesh representation.

OpenSubdiv: Optimize topology refiner

Avoid allocation and gathering of edge and face connectivity information
when ordering vertex edges/faces.

Still not totally optimal, but gives 2x speedup for refiner creation.

GP Sculpt: Shift-F affects brush strength, and Ctrl-F affects brush size

These hotkeys do not work when the brush is being used...

GP Sculpt: Dampen Pinch brush strength

By trial and error, it seems that dividing the influence by 5 makes this tool
more manageable.

OpenSubdiv: Fix some typos from previous commit

GP Sculpt: Pinch brush can now be inverted using Ctrl (i.e. "Inflate")

Just like with the mesh sculpting tools, holding Ctrl can now be used to
apply the inverse transform when using the pinch brush. So, instead of
drawing the points towards the brush, Inflate will push them away.

OpenSubdiv: Initial wok over separation of legacy and new evaluators

Since the CCGSubSurf.c file started to grow rather insanely and not being
possible at this moment to drop old evaluator it makes sense to split
evaluators into own files. This way code becomes a bit easier to follow,
plus in the future it should help isolating and removing code which is
no longer used.

Still some polishing is possible, but need to get started somewhere.

GP Sculpt: Initial implementation of "Pinch" Brush

This brush draws all the points inwards towards the midpoint of the brush.
I'm not sure if this brush is really that useful or not, so I'll leave it
as-is for now.

Watch out for how strong you set the brush to be; even with 0.3, you can already
get some really strong/rapidly changing results.

Merge branch 'master' into temp-derivedmesh-looptri

Fast drawing for sculpting multires using VBOs (non VBO won't have
fast mode but will not spend time on that).

With this commit branch should be in full feature parity with master.
