Fix crash when making local object+obdata with linked armature.

Reported by Andy Goralczyk (@eyecandy) over IRC, thanks!

Simply nuke all that poor broken custom one-by-one handling in
object_relations.c code, and use highly complex but powerful and
well-tested BKE_library_make_local() in all cases of MakeLocal!

ID management, especially related to linking, is very hairy matters,
better to have as few as possible core functions managing all the dirty
details. ;)
