Sculpt: Cloth Brush simulation area property

This makes possible to choose between a local and a global simulation
when the cloth brush is used. Local simulation is the current default.
When global simulation is enabled, the cloth brush simulates the entire
mesh without taking any simulation limits into account.

This was possible before by setting the simulation limits to 10 (the
current maximum value allowed) so the entire mesh was inside the limits,
but this was a hack as the limits scale with the radius and there should
not be any limitation on how big the simulated area can be to be able to
simulate an entire object. This also allows to make a more clear
distinction between cloth brush presets that are intended to be used in
local areas to add details or globally to generate the base shape of the
mesh.

Some minor cleanup in the patch.

Cleanup: Paint Cursor Refactor

The paint_draw_cursor function was handling the cursor drawing for 2D
and 3D views of all paint modes, calculating the brush radius, updating
the SculptSession data and updating and drawing all sculpt cursor
overlays for different tools. It was almost impossible to understand when
and what was being drawn and in which state the GPU matrix was.

Now everyting is organized into different functions, with clear
separation between modes, sculpt tool overlays and different drawing
setups. Update and drawing functions are also separated (this allows to
skip one PBVH query on each cursor drawing).

Cleanup: Stop accessing gpu_batch_presets_reset()

The current code is accessing this from outside the gpu "namespace". As
such it should be accessing GPU_ functions, not gpu_ functions.

This is also a place to centralize the XXX message that will be
addressed upon refactor. So we can reuse this call in other places that
need the same temporary workaround.

Cycles: load OpenVDB file earlier in Blender export

In an upcoming bugfix we'll use OpenVDB data structures directly to build mesh
for sparse OpenVDB volumes, loading them OpenVDB grids earlier and removing any
references to Blender data structures makes that easier.

This also makes changes to Blender volumes to support this, so Cycles can take
ownership of a grid without Blender having to keep its own reference to it.
This should also be useful in a future Python API.
