Went through all the code and tried to document lock and thread usage
in the module. There's a huge comment block introducing all of this
at the beginning and I believe it's correct (though not quite complete).
Keep it updated, people. Added a new state, WAIT_HTTP_RESOURCE, that's
sort of a side-state of SEND_HTTP_REQ. If we hit a high-water mark
for HTTP requests, the extra are shunted to the new state once. Once
levels fall to a low-water mark, we run through a wait list of UUIDs,
sort the valid ones by priority and release them for service. This
keeps the HTTP layer busy while leaving the active queue shallow enough
that requests can still be re-prioritzed cheaply. Priority model
changed. The new state uses the PRIORITY_LOW mask, the old users
of _LOW are now at PRIORITY_NORMAL and sleepers woken up after an
external event are kicked off at PRIORITY_HIGH. This combination
along with the new state should avoid priority inversion and keep
things running without resorting to an infinite pipeline. New
state displays as "HTW" with green text in the texture console.
Request cancelation and worker run-down should now be more
correct but this edge case may need more attention.
changed ordering of template loading relative to constructor setting of params
moved a lot of constructor-set params to template files

EXT-8445 Reduce baked texture timeout fro 120sec to 60sec default
Also did some minor infrastructure cleanup, added code comments, etc. There is now separate logic for determining how to handle update (versus upload) requests.
Also made a trivial change to llvoavatar to properly encapsulate mAppearanceAnimating.
Also reduced the baked texture timeout to 60s (in settings.xml)
EXT-7504 WIP Force decloud after timeout using lower res textures
Better formatting for baked texture information.
Also added exponential timeout for sending low res baked textures.
EXT-7526 FIXED Add baked texture information to texture view
First attempt at low res textures after timeout.
Added debug setting to control whether low res texture timeout is used.
Added baked texture load information to texture view debug display.
Trivial name changes to some variables.
* Fixed bug in llqueuedthread.cpp causing unnecesssary sleeeping
* Fixed an issue that was preventing retries on 503 errors
* Added number of pending creates to Texture View
* Increased time allocated for texture creates
