Do not use a timer for HTTP get in LLTextureFetchWorker::doWork

All HTTP timing is done by AIHTTPTimeoutPolicy.

Inside LLTextureFetchWorker::doWork when mState == SEND_HTTP_REQ,
mCanUseHTTP is true, throttling is not in effect and mURL is not empty,
mLoaded is set to FALSE, mState is set to WAIT_HTTP_REQ and
LLHTTPClient::request is called that starts the download by curl.
A call back to LLTextureFetchWorker::callbackHttpGet is guaranteed,
which causes mLoaded to be set to TRUE (HTTPGetResponder::completedRaw
calls LLTextureFetchWorker::callbackHttpGet which sets mRequestedSize to -1
(if there was an error) and mLoaded to TRUE).

Being in state WAIT_HTTP_REQ, once mLoaded == TRUE (and mRequestedSize
is -1), the different timeout errors are handled.
Avoid assertion in ~AIStateMachine upon viewer exit.

Force the state to bs_killed before clearing the list of statemachines
in AIEngine::flush().
Stabbed some blendfunc state issues. This fixes some ui flicker which popped up recently (perhaps after merging, or I just never noticed it before then)
Clamp LLMeshSkinInfo::mJointNames to a max of 64 entries. Also checking size in lldrawpoolavatar(Redundant checks added to just match similar logic LLRiggedVolume::update more closely.)
Added blendfunc checks when RenderDebugGL is TRUE.
Commented out a spammy llinfos message.

SH-4044 FIX voice dot is offset vertically if using avatar height offset

Added the height offset in one too many places. fixing.
SH-4050 FIX camera goes below ground when avatar offset set to 0

Added a constraint to ensure that the avatar's height (with offset)
does not go below 0.1 meters. Camera was getting confused since the avatar's
effective height was negative.

Note the avatar is mostly underground/contorted even at 0.1 meters, but
most users setting values this low will be making ultra-tinies and would
be hiding the avatar mesh. Camera stays above ground when height is at 0.1.

SH-4059 FIX other's hover parameters affects your avatar's setting

Added an additional sanity check to make sure that other avatars don't
affect your wearables.
