Fix filtering in new UIList bookmarks & co.

Better sorting when we are displaying several levels at once, for 'lib' append/link.

Consider blendfiles and 'categories' inside them as regular dirs, but with this hierachy:
real dir > blende file lib > category in a blend lib.

This gives a much better sorting (among other things, gives more importance to
blend files!).

Depsgraph: Whole IK chain depends on the solver result

This is the only way we can make sure all needed calculations are done
to the time BKE_pose_bone_done() is called.

Depsgraph: Use BLI_gset_add() instead of BLI_gset_insert() to avoid duplicate entries in set

So it turns out that using BLI_gset_insert() will just cause the ghash-set
implementation to blindly add duplicate entries if the key already exists
in the hashtable - not exactly what we want, as that kindof violates the
whole point of such data structures.
