Basic strand processing in the hair sim cache modifier.

Sequencer cleanup: create seq_render_image_strip() function

Sequencer cleanup: create seq_render_movie_strip() function

From review: Sequencer Scene strips were forcing rendering to happen multiple times

This was more a cache issue. Images and Movies were having the same
problem, but they went unnoticed.

This is not an ideal solution, but it works decently enough. @psy-fi may
want to pitch in on that.

Depsgraph: Correction to previous commit: non-geometry objects had more than one parameter eval nodes

Depsgraph: Use plain const char* for nodes typeinfo

Depsgraph: Correction to parameters animation commit

Drivers are handled a bit differently, so can't really create
relation between animation component and parameters without
having action.

Depsgraph: Attempt to solve issues with using object's id props as driver target

Revert "Always display full data paths in tooltips"

Seems like there is currently now way to get the full data path
reliably. So instead of the old "..." this patch just displays
(null) which also isn't really useful.

Depsgraph: Use pointer to a cons char instead of a string for relation name

Clean up vertex/normal client state after drawing strands.

This should hopefully prevent some random crashes.

Always display full data paths in tooltips

Another experiment for gooseberry. We should make Blender smarter
here in general, but it's a start.

Depsgraph: Improve handling of unexisting RNA paths in driver targets

Depsgraph: Avoid creating anim->parameters relation when there's no anim node

Merge branch 'master' into asset-experiments

Depsgraph: Fix some issues with node bulding

Mainly this commit addresses issues when same operation node
was trying to be created twice.

It also fixes wrong key used for effector's psys operation.

More cleanup and interface resurrected

Fix an invalid operation

Exit without leaks and crashes.

More API changes, get rid of indexBufferDataGLSL (we can reuse vertex
streams effectively here)
