Bring in Oz's tweaks to the way BugSplat is engaged and tested, plus a few
other miscellaneous goodies.

NickyD discovered that the substitute default allocator used for llcorehttp
tests was returning badly-aligned storage, which caused access violations on
alignment-sensitive data such as std::atomic. Thanks Nicky!!
Moreover, the llcorehttp test assertions regarding memory usage, well-
intentioned though they are, have been causing us trouble for years. Many have
already been disabled.
The problem is that use of test_allocator.h affected *everything* defined with
that header file's declarations visible. That inevitably included specific
functions in other subsystems. Those functions then (unintentionally) consumed
the special allocator, throwing off the memory tracking and making certain
memory-related assertions consistently fail.
This is a particular, observable bad effect of One Definition Rule violations.
Within a given program, C++ allows multiple definitions for the same entity,
but requires that all such definitions be the same. Partial visibility of the
global operator new() and operator delete() overrides meant that some
definitions of certain entities used the default global allocator, some used
llcorehttp's. There may have been other, more subtle bad effects of these ODR
violations.
If one wanted to reimplement verification of the memory consumption of
llcorehttp classes:
* Each llcorehttp class (for which memory tracking was desired) should declare
class-specific operator new() and operator delete() methods. Naturally,
these would all consume a central llcorehttp-specific allocator, but that
allocator should *not* be named global operator new().
* Presumably that would require runtime indirection to allow using the default
allocator in production while substituting the special allocator for tests.
* Recording and verifying the memory consumption in each test should be
performed in the test-object constructor and destructor, rather than being
sprinkled throughout the test<n>() methods.
* With that mechanism in place, the test object should provide methods to
adjust (or entirely disable) memory verification for a particular test.
* The test object should also provide a "yes, we're still consuming llcorehttp
memory" method to be used for spot checks in the middle of tests -- instead
of sprinkling in explicit comparisons as before.
* In fact, the llcorehttp test object in each test_*.hpp file should be
derived from a central llcorehttp test-object base class providing those
methods.

Hopefully this is temporary until we solve the problem of crashy llcorehttp
test executable on Mac.

cmake -E copy does only one file at a time, and older CMake versions don't
handle wildcards. But cmake -E copy is specifically for portability. When the
copy operation itself is Darwin-only, we can count on having 'cp' available.

since we no longer support 32-bit Mac builds.
The old build-darwin-i386 directory name appeared in a shocking number of
files. Change CMake paths to use ${CMAKE_BINARY_DIR} -- or, when trying to
find the packages subdirectory, ${AUTOBUILD_INSTALL_DIR}. Change the rest to
at least look for build-darwin-*.

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.

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.
