Sim apparently sends finish and start messages simultaneously in case of
scripted or experience teleports

Finally reverting the MAINT-4488 (see BUG-37693 for details)

MAINT-6385: Ensure that VMM initialization only happens once after login and that it will only happen after the region caps have been received.

--HG--
branch : RLVa

MAINT-5831: If there is a teleport request active and it has failed, teleport state will always return "None".

MAINT-5693: Consolidated the avatar appearance request into a coroutine.  If the request fails because of a stale COF, then rerequest with the corrected one.

--HG--
branch : MAINT-5575

Removed sdhandler from llagent.
Removed unused values from llacountingccostmgr
Fixed smart pontier creation in llfacebook

Changed language, appearance, and maturity to conform to use the adapter rather than the SDHandler

Added get/setRequestURL() to LLCore::HttpResponse
Removed URI from the HttpSDHandler.
