Subject: Thank you kindly, Idb for a patch that solves: The following should
 silently fail when attached, llBreakAllLinks, llBreakLink, llCreateLink. The
 following should be restricted to avatars in the same sim, llGetAgentInfo,
 llSameGroup, llGetAgentSize, llGetAnimationList. Comment added to the
 following unimplemented functions, llGetAgentLanguage, llGetAnimation.
