legacy coding policy fix-up.

Replace LLEventPump's boost::scoped_ptr<LLStandardSignal> with
boost::shared_ptr. Take a local stack copy of that shared_ptr in post()
methods, and invoke the signal through that copy. This guards against scenario
in which LLEventPump gets destroyed during signal invocation. (See Jira for
details.) Re-enable Mani's test case that used to crash.
Introduce ll_template_cast<> to allow a template function to recognize a
parameter of a particular type.
Introduce LLListenerWrapper mechanism to support wrapper objects for
LLEventPump listeners. You instantiate an LLListenerWrapper subclass object
inline in the listen() call (typically with llwrap<>), passing it the real
listener, trusting it to forward the eventual call.
Introduce prototypical LLCoutListener and LLLogListener subclasses for
illustrative and diagnostic purposes. Test that LLLogListener doesn't block
recognizing LLEventTrackable base class bound into wrapped listener.

with an event API. In addition to the LLEventPump name on which to listen,
LLEventAPI accepts a documentation string for event API introspection.
Give every LLEventDispatcher::add() overload a new documentation string
parameter for event API introspection.
Convert every existing event API to new conventions, introducing suitable
documentation strings for the API and each of its operations.

For both the (so far unused) generic KEY form and the KEY = T* form, provide
key_iter, beginKeys(), endKeys().
Change instance_iter so that when dereferenced, it gives you a T& rather than
a T*, to be more harmonious with a typical STL container. (You parameterize
LLInstanceTracker with T, not with T*.)
Fix existing usage in llfasttimer.cpp and lltimer.cpp to agree.
For the KEY = T* specialization, add T* getInstance(T*) so client isn't forced
to know which variant was used.
Add unit tests for uniformity of public operations on both variants.

Fixed mac breakage.

Should now work out of the box on all 3 platforms and in the debugger.

Infrastructure changes for cleaning up Asset/Folder types.  Associated sim changes are only so that the sim still compiles.

Beginning work for DEV-41722 normalizing shared lib staging on all 3 platforms.  Renamed CopyWinLibs.cmake to Copy3rdPartyLibs.cmake.

* turn llnamevalue_tut into a llmessage unit test
* turn llsdserialize_tut into a llcommon integration test
* re-enable the (quite slow) llsdserialize test on win32 now that it doesn't have to run on every recompile
* re-enable all llmessage unit tests on linux viewer builds

DEV-41080 - I found out why llmath can't be unit tested and fixed it, this checkin is some harmless preparation for that...

Propagate QAR-1814 to trunk.

The problem arose because we were setting LL_COMMON_BUILD in
llcommon/CMakeLists.txt, not only for the library build itself but also for
its LL_ADD_INTEGRATION_TEST tests. This told all the headers compiled into the
INTEGRATION_TEST_lllazy executable that the executable was providing all the
llcommon symbols, rather than importing them.
The solution is to switch to the llcommon_EXPORTS symbol automagically defined
by CMake when building the llcommon shared library itself.

Includes:
* DEV-31909 VWR-13251: Revise lscript_library.cpp to allow localization of LSL editor hovertips
* DEV-21938 llSHA1String does not appear where expected in the dropdown "Insert" menu in the LSL editor
* Some cleanup to llerror so that it doesn't depend on llfixedbuffer
* A few misc. server specific changes not related to the texture-pipeline changes (llapp, lloptioninterface)

LL_ADD_INTEGRATION_TEST supports tests that may require linking against one or
more Linden libraries, or that should be executed with a wrapper script.
Use this to test lllazy.cpp, llsdmessage.cpp and llcapabilitylistener.cpp.

Some branch shenannigans in the pluginapi_05 branch caused this to become a two-part merge.

Attemt at fixing "doubleton" problems across shared lib boundaries.  Singletons now keep their SingletonInstaceData in a big global map in the llcommon module.

Resources subdir without requiring user to explicitly set DYLD_LIBRARY_PATH.
Engage the SHARED_LIB_STAGING_DIR mechanism for Mac as well as Windows and
Linux so unit-test executables, too, can find libllcommon.dylib. Perform the
POST_BUILD copy of libllcommon.dylib to SHARED_LIB_STAGING_DIR everywhere but
Windows -- but make it conditional on SHARED_LIB_STAGING_DIR.
