Fix prim link numbers (Mantis #1781)

Implements additional unlink modes (unlink root prim from link set, some
multi-set operations). Linking (single and mutiple) fully implemented.
Consistent numbering of links while in world. Link/delink with predictable
link numbering. Correct link numbers in LSL.
Not all multi-set ops implemented. Link numbers still change when taken and
re-rezzed.
