so path manipulation functions dont run multiple times on the same path in the case of sequence strips where the one directory is used as the base for many images.
Added a visitor function to simplify processing of file paths that are attached to IDs. This is used for images, and could be used for other ID types in future.

vecs = Camera.view_frame(scene)
returns 4 points for the camera frame, without this its very hard to know if a point is in the camera view or not, without rewriting blenders internal logic in python.

- particle.c wasn't setting all components of the vector when reading cache and setting dummy velocity values.
- some functions incorrectly took a float[3] argument when the 4th value was set.
- remove a few redundant lines of code.
This fixes bug #26764 and several others like it, where modifier
properties (and others, but most visibly modifiers) would not do
anything when animated or driven, as modifier properties require the
RNA update calls to tag the modifiers to get recalculated.
While just adding a call to RNA_property_update() could have gotten
this working (as per the Campbell's patch attached in the report, and
also my own attempt #25881). However, on production rigs, the
performance cost of this is untenatable (on my own tests, without
these updates, I was getting ~5fps on such a rig, but only 0.9fps or
possibly even worse with the updates added).
Hence, this commit adds a property-update caching system to the RNA
level, which aims to reduce to the number of times that the update
functions end up needing to get called.
While this is much faster than without the caching, I also added an
optimisation for pose bones (which are numerous in production rigs) so
that their property updates are skipped, since they are useless to the
animsys (they only tag the depsgraph for updating). This gets things
moving at a more acceptable framerate.

Also fixed an inconsistent conflict resolution in the last commit with
regard to release/scripts/startup/bl_ui/properties_render.py. This
problem resulted in empty menus in the GUI.
Vertex parents were not requesting the original index layer, now do this as
part of depsgraph building, and make constraints with vertex groups use the
same system. Fix is based on patch by Campbell, but with some changes.
