Fix for incorrect vertex loops when calculating strands.

This was using vprev from previous strands, leading to spurious changes
on untouched strands when combing.

Cleanup.

Cycles, OpenVDBManager: split routines into separate functions.

Cycles: add OpenVDBManager::delete_sampler convenience function.

Cycles: move routine to find an exiting grid slot to its own function.

Cycles: add grid memory usage to logging.

Use the extended archive writer variant to set the correct start frame
for slices.

Also the time sampling for slice output properties must be passed down
from the output archive, since the input properties use the original
start frame and cycle times.

Cycles: use ccl_fetch to get the shading point position.

Use fps and start frame settings for cache archives internally, rather
than relying on values from Scene.

This gives more flexibility when creating archives. A default variant
for opening archives using the scene settings is still available.

New operator for 'splicing' Alembic data, i.e. writing part of the frame
range to a new archive.

This feature is useful when cache size becomes to big and unwieldy.
For sending shots to a render farm a large cache can now be split into
smaller parts, which are spliced off and can be sent individually.

Scrubbing after movie has finished playing works now

Initial support of audio scrubbing in blenderplayer.

Still lots of corner cases to check:

* sound FPS not changing with speed settings of player
* picture and video still not 100% in synch
* Haven't checked what happens when audio is finished.

Some changes were made to make things nicer:

* Scrub now initiates on mouse click instead of mouse motion, makes
things more predictable.
* When scrubbing a movie with sound, don't pause playing after
scrubbing.

WIP patch for OpenVDB integration in Blender and Cycles

As requested by a handfull, here's some code :)

(NOTE:) you'll need to disable compilation with OSL and install OpenVDB separately.

Reviewers: dingto, lukastoenne, sergey

Subscribers: levon, #cycles

Differential Revision: https://developer.blender.org/D1308

Export: take adaptive domain into account (still a bit off but seems to
work)

Optional arguments for the cache baking operator to chose a frame range.

If these properties are left undefined the operator will use the scene
frame range as before.
