Mesh code.
Pay correct attention to status codes coming back from services. Generate
better and consistent error messages when problems arise. There's more to
do in error handling, need a way to cleanly fail all request types, only
have that for LOD at this point. Do better keeping the HTTP pipeline between
the low and high water marks. This was made challenging because the outer
most code couldn't really see what's going on internally (whose actions are
delayed in a worker thread). More to do here, the debug-like requests don't
honor limits, that will come later. Made retry counts available from llcorehttp
which can be used by the throttle-anticipating logic to advance the count.
It helps but it reinforces the coupling between viewer and server which I
do not like.

Mesh repo is using three policy classes now: one for
large objects, one for GetMesh2 regions, one for
GetMesh regions. It's also detecting the presence
of the cap and using the correct class. Class
initialization cleaned up significantly in llappcorehttp
using data-directed code. Pulled in the changes to
HttpHeader done for sunshine-internal then did a
refactoring pass on the header callback which now
uses a unified approach to clean up and deliver
header information to all interested parties. Added
support for using Retry-After header information on
503 retries.

Header container moves from a vector of raw lines to a vector
of string pairs representing name/value pairs in headers. For
incoming headers, we normalize the name to lowercase and trim
it. Values are only left-trimmed. Outgoing headers are left
as-is. Simple find() method for the common case, forward and
reverse iterators for those few who need to do it themselves.
The HTTP status line (e.g. 'HTTP/1.1 200 Ok') is no longer treated
as a header to be returned to caller. Unit tests, as usual,
were a bear but they absolutely ensured outgoing HTTP header
conformance after the change. Grunt work paid off.
LLTextureFetch was also given a second options structure
for texture fetches. Same as the original but with header return
to caller requested. Baked textures should use this, the other
20,000 texture fetch requests should continue to use the original.

Added second mesh class as well as an asset upload class.
Refactored initialization to use less code and more data to
cleanly get http started. Modified mesh to use the new
http class for large requests (>2MB for now). Added additional
timeout setting to llcorehttp to distinguish connection timeout
from transport timeout and are now using transport timeout
values for large asset downloads that may need more time.

Introduce LLCoros::setStackSize(), with a compile-time default value we hope
we never have to use. Make LLAppViewer call it with the value of the new
settings variable CoroutineStackSize as soon as we've read settings files.
(While we're at it, notify interested parties that we've read settings files.)
Give CoroutineStackSize a default value four times the previous default stack
size. Make LLCoros::launch() pass the saved stack size to each new coroutine
instance.
Re-enable lleventcoro integration test. Use LLSDMap() construct rather than
LLSD::insert(), which used to return the modified object but is now void.

Bleh, had some old initialization code in place that meant I was using
32 connections. (Always verify with 'netstat'...) Logic is now to
use 1/4 of MeshMaxConncurrentRequests to head in the direction of 8
at a time. Full count is used to implement a high-water level keeping
llcorehttp in work.

Conversion was mostly trivial. Did some refactoring in the conversion
of Responders to Handlers which eliminated 5X code replication. More
will be done especially as this is extended to deal with the various
possible combinations of 200/206/416 status for ranged gets. There are
a lot of thread races in the existing code, that is going to need some
real attention. And the scheduling/liveness logic in the thread
management bounces around from thread to thread wasting a lot of time
and using expensive synchronization. Much can be done here. But the
result is that the 8 connections in the Mesh corehttp class now perform
as did the 32 connections of the original. And that 32 actually looks
like it could bleed to over 64. So, progress...

Pull cpu-based metrics into llcorehttp work to enable A/B
testing. Simple merge.

First version running with all five downloaders converted. Not certain
all are functional yet and the whole thing is slow but it is running.

Initial work completed on linux, moving over to windows to do debug
and refinement. This includes 5/6 handlers based on existing responders
and use of llcorehttp for the mesh header fetch.

Integrated as a ctor-time option to LLDeadmanTimer and have mesh

One of the metrics calls was running in an LLCurl-owned thread
doing responder invocation. Deleted that invocation and will
do with the other safe ones. Added a boost signal on the
TeleportStarted message which is now used to restart the metrics
timer. I think I'd like to move the metric blob into a free-
standing entity later...

Timer interface violated my design rules and I paid for it
with clumsiness and silent errors. Cleaned it up mainly
removing the evil default values. Found better integration
points in the mesh downloader and it's producing fairly
consistent numbers on the MeshTest2 test region (about
5500 downloads, ~90 seconds, +/- 10 seconds). Will review
with davep and do an early timer stop on teleport which
invalidates a timing sequence.

llviewerregion deletion. Avoid trying to send metrics when we're shutting down and it's too late anyway. Reviewed by Nyx
