Adding a new visual param that allows users to manually adjust an offset for
how far off the ground (+ or -) their avatar's root bone is.
Supports the +-2m range people are used to adjusting in their viewers, but
new implementation should support server-generated appearances.

Pretty much add support for sending LLAvatarName and std::string to become a name via the system...
Also a bit of a revert for llcallingcard.cpp in this regard, just allow it to use a callback along with the new support,
but still handle the actual name switching in LLAvatarNameCache.
Fixes a problem I was having with "[NAME] is Online" notifications appearing early on, only.
Only does that, dun believe me? Take a look, oh... it also corrects improper interpretations of the PhoenixNameSystem value: 1 is both, 2 is displays, 0 and anything else is Legacy.
Also replaces a bit of the display name support code with new system... by definition this shouldn't change the log file, only the title of the session..
because of my bad connection during week days, I can not confirm this working 100%,
but if it does end up changing the logs under certain unseen conditions, replace the new name check with gCacheName->getFullName(id, name) but this reallllly shouldn't happen!
Added LLObjectList::getAvatar(LLUUID) for type-safe and quicker lookup
Added F32 overload to LLSD because using F64 needlessly is silly.
(And its lack of F32 overload caused issues with LLCachedControl<F32>)
