In recent versions of Boost, BOOST_THREAD_LIBRARY depends on
BOOST_SYSTEM_LIBRARY. In llcorehttp/CMakeLists.txt, these were
incorrectly ordered for Linux. Somewhat oddly, that appears to have
caused Linux link errors even in llmath. Fix at least this problem.

Sometimes it can be useful to have http_proxy set in the environment, but if
we leave it set while INTEGRATION_TEST_llcorehttp is running, the test hangs.
Suppress that variable for that integration test.

point to duplicated code. Replaced hard-coded tcmalloc link option with variable that is created in GooglePerfTools.cmake.

Cmake files not merged correctly and had to be done by hand. New memory
allocation made some memory usage tests in the llcorehttp integration
tests no longer valid. Would like to work on LLLog sometime and get
it to be consistent. Special flags needed for windows build of example
program.

Groundwork is used for the default class which currently represents
texture fetching. Class options implemented from API user into
HttpLibcurl. Policy layer is going to start doing some traffic
shaping like work to solve problems with consumer-grade gear.
Need to have dynamic aspects to policies and that starts now...

Initial version that should have enough of the plumbing to produce
a working adapter. Memory test is showing 8 bytes held after one
of the tests so I'm going to revisit that later. But basic
functionality is there going by the unit tests.

numbers.
This is a command-line utility to pull content down from a service through
the llcorehttp library to produce timings and resource footprints.

Implemented/modified PUT & POST to not used chunked encoding for the request.
Made the unit test much happier and probably a better thing for the pipeline.
Have a cheesy static & dynamic proxy capability using both local options and
a way to wire into LLProxy in llmessages. Not a clean thing but it will get
the proxy path working with both socks5 & http proxies. Refactoring to get
rid of unneeded library handler and unified an HttpStatus return for all
requests. Big batch of code removed as a result of that and more is possible
as well as some syscall avoidance with a bit more work. Boosted the unit
tests for simple PUT & POST test which revealed the test harness does *not*
like chunked encoding so we'll avoid it for now (and don't really need it
in any of our schemes).

This brings in a copy of llmessage's llsdmessage testing server. We run
a mocked HTTP service to handle requests and the integration tests run
against it by picking up the LL_TEST_PORT environment variable when running.
Add some checks and output to produce useful info when run in the wrong
environment and when bad status is received. Later will add a dead port
as well so we can test that rather than use 'localhost:2'.

Implemented first global policy definitions to support SSL CA certificate configuration
to support https: operations. Fixed HTTP 206 status handling to match what is currently
being done by grid services and to lay a foundation for fixes that will be a response
to ER-1824. More libcurl CURLOPT options set on easy handles to do peer verification
in the traditional way. HTTP POST working and now reporting asset metrics back to
grid for the viewer's asset system. This uses LLSD so that is also showing as compatible
with the new library.

Identified and reacted to the priority inversion problem we
have in texturefetch. Includes the introduction of a priority_queue
for the requests that are ready. Start some parameterization in
anticipation of having policy_class everywhere. Removed _assert.h
which isn't really needed in indra codebase. Implemented async
setPriority request (which I hope I can get rid of eventually along
with all priorities in this library). Converted to using unsigned
int for priority rather than float. Implemented POST and did
groundwork for PUT.

This is the first functional viewer pass with the HTTP work of the texture fetch
code performed by the llcorehttp library. Not exactly a 'drop-in' replacement
but a work-alike with some changes (e.g. handler notification in consumer
thread versus responder notification in worker thread).
This also includes some temporary changes in the priority scheme to prevent
the kind of priority inversion found in VWR-28996. Scheme used here does
provide liveness if not optimal responsiveness or order-of-operation.
The llcorehttp library at this point is far from optimally performing.
Its worker thread is making relatively poor use of cycles it gets and
it doesn't idle or sleep intelligently yet. This early integration step
helps shake out the interfaces, implementation niceties will be covered
soon.

hard stall
while allocating the first easy handle in a descent of the global initiailization
code but that doesn't seem to be a problem on TC machines. Perhaps the static
linking is creating multiple data copies. More work needed.

defenses in the delete functions of the allocation support. General
boost library renaming again. Linux builds in TC though it shouldn't
based on what Boost.cmake lookes like...

boost::thread and the easiest path to that was to go with the 1.48 Boost release
in the 3P tree (eliminating a fork for a modified 1.45 packaging). One unit test,
the most important one, is failing in test_httprequest but that can be attended
to later. This test issues a GET to http://localhost:2/ and that is hitting the
wire but the libcurl plumbing isn't delivering the failure, only the eventual
timeout. An unexpected change in behavior.

The unit/integration tests don't work yet as I'm still battling cmake/autobuild
as usual but first milestone passed.
