Constraints: refactor the D7437 patch adding Custom Space for constraints.
As mentioned in the comments to that patch, I had an idea for
a different way to do some technical aspects, but it was too
complicated to force changes in the original patch. Thus I submit
this follow up patch.
First, instead of modifying all the get_constraint_targets and
flush_constraint_targets callbacks, introduce wrapper functions
for accessing constraint targets, convert all code to use them,
and handle the new reference there uniformly for all constraints.
This incidentally revealed a place in the Collada exporter that
didn't clean up after retrieving the targets.
Also, tag the special target with a flag so other code can
handle it appropriately where necessary. This for instance
allows dependency graph to know that the Use B-Bone Shape
option doesn't affect this specific target.
Finally, rename and simplify the function for initializing the
custom space, and make sure it is called everywhere necessary.
