This is now necessary since the curl thread no longer syncs with the
main thread: it is possible that a request finishes after a texture
fetch thread was shot down but before curl was stopped, and curl
calling BufferedCurlEasyRequest::processOutput while objects that the
responder uses were already destructed (most notably
LLTextureFetch itself).
Doing this resulted in a 404 on Aditi, and although that was a server
bug; it still doesn't seem to make much sense to do the request in the
first place.
We were using an indicator of whether there *was* a baked texture to whether we
were *using* a baked texture. Switched to one of the (several) proper indicators
of whether a baked texture was in use. This should allow local texture data to
get marked for download when we enter appearance mode.
Local testing confirms that old apperances linger for a second or two, but are
soon replaced by the correct local renders.
We suppress texture downloads for local textures not needed with server side
baking. We need to explicitly re-set texture priority for local textures
when entering appearance mode.
Wearable parsing error caused last texture in some assets to fail to parse.
Parser now does not throw an error if the wearable does not end in a newline
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.

This value really IS in bytes/s (not for the total), and apparently 56
kB/s is too optimistic. The value was used by LL for transfers that went
beyond the total download time (2 minutes?), adding enough seconds per
received bytes to the timeout to allow a download at 56 kB/s to finish.
Our meaning is different however: we time out immediately and whenever
the download drops below this speed.
Perhaps a better algorithm is where the speed demand is based on the
total size of the download, but I'm not sure we always know the size of
downloads at this point.
When uploading finishes, but is not detected, the timeout should be for
"reply delay", the time that the server takes before it replies, and not
CurlTimeoutLowSpeedTime. This patch adds code that takes this failure
into account (which happened only ONCE for me on Metropolis while flying
around and using trickle (not sure if that is relevant), so it's not
that likely to improvement anything in practise. Note that it is
detected by an assertion when it happens, so that we can safely assume
it normally never happened on SL).
* Generalized PUT / POST configuration by adding
CurlEasyRequest::setPut, which now also supports keep-alive (which
still isn't used).
* Upload content length is now stored in CurlEasyRequest::mContentLength
* CurlEasyRequest::has_stalled() now return false if it was possbile
that the 'upload finished' detect failed AND calls upload_finished()
itself in that case, so it is no longer 'const'.
* If low speed is detect exactly when the last bytes are being attempted
to be sent (unlikely scenario), then the upload gets 4 more seconds
after which is switches to CurlTimeoutReplyDelay.
* Added EDoesAuthentication and EAllowCompressedReply to replace
booleans, for readability and type-safety, as did EKeepAlive. Note
that this change inverts the meaning of the compression related parameter.
* Unrelated: removed an unnecessary #include "llurlrequest.h" from
llxmlrpcresponder.h
When a state machine is aborted after it switched to bs_initialize,
but before it executed initialize_impl(), then we should set the
state back to bs_reset and abort cleanly by switching to bs_killed
and then handle that. Before the state was set to bs_abort, resulting
in calling abort_impl(), finish_impl(), the call back and unref()
for an not initialized state machine! (detected by the assert that
makes sure that ref()/unref() are called in balance).
