This patch implements llMessageLinked.

I had to make a change to llGetLinkNumber to return m_host.LinkNum + 1 for
link sets of more than 1 prim, or 0 for a single object, since according
to:

http://rpgstats.com/wiki/index.php?title=LlMessageLinked

linksets with 2 or more prims start the link numbering at 1, but a single
prims link number is 0.
