Integration of particle shapekeys with the depsgraph and driver eval.

It's a bit messy, but that is to be expected: all of the areas involved
(particles, shapekeys, depsgraph, drivers) are badly designed and
supposed to get major refactoring ...

Use the X mirror option in new strand edit stroke brush tools.

Note that currently this has virtually no effect, because the mirror
option relies on exact positions of vertices, which does not happen with
random hair placement (the add brush has no mirror option yet).

Eventually topological mirroring should help with this case, but is not
implemented for either old or new strand edit yet.

Cleanup: rename function argument for consistency.
