More pose armature code factorization:

* New armature_mat_bone_to_pose, which is just the reverse of armature_mat_pose_to_bone (currently used by armature evaluation code only, but might be used by constraints space conversion code too, see note below).
* Found another place where another (a bit erroneous) pose_to_bone code existed (apply_targetless_ik(), in transform_conversion.c, used by "auto ik" option), replaced it by a call to armature_mat_pose_to_bone.

Notes:
* All those changes leave many #if 0 commented code, I will remove those in a few weeks.
* There is at least one other place where generic armature_mat_(pose_to_bone/bone_to_pose) functions should be usable: the space conversion function of constraints (constraint_mat_convertspace(), in BKE's constraint.c), but here I have some problems (old code is also somewhat erroneous, but using new one makes old rigs using bone space constraints wrong, e.g. sintel one, and it’s just impossible to make conversion code...). So I'll wait and investigate more for this one.
