Two sleep() methods: one accepting F32Milliseconds, or in general any LLUnits
time class; the other accepting any std::chrono::duration.
The significant thing about each of these sleep() methods, as opposed to any
freestanding sleep() function, is that it only sleeps until the app starts
shutdown. Moreover, it returns true if it slept for the whole specified
duration, false if it woke for app shutdown.
This is accomplished by making LLApp::sStatus be an LLScalarCond<EAppStatus>
instead of a plain EAppStatus enum, and by making setStatus() call set_all()
each time the value changes. Then each new sleep() method can call
wait_for_unequal(duration, APP_STATUS_RUNNING).
Introducing llcond.h into llapp.h triggered an #include circularity because
llthread.h #included llapp.h even though it didn't reference anything from it.
Removed. This, in turn, necessitated adding #include "llapp.h" to several .cpp
files that reference LLApp but had been depending on other header files to
drag in llapp.h.

LLThread::currentID() used to return a U32, a distinct unsigned value
incremented by explicitly constructing LLThread or by calling LLThread::
registerThreadID() early in a thread launched by other means. The latter
imposed an unobvious requirement on new code based on std::thread. Using
std::thread::id instead delegates to the compiler/library the problem of
distinguishing threads launched by any means.
Change lots of explicit U32 declarations. Introduce LLThread::id_t typedef to
avoid having to run around fixing uses again if we later revisit this decision.
LLMutex, which stores an LLThread::id_t, wants a distinguished value meaning
NO_THREAD, and had an enum with that name. But as std::thread::id promises
that the default-constructed value is distinct from every valid value,
NO_THREAD becomes unnecessary and goes away.
Because LLMutex now stores LLThread::id_t instead of U32, make llmutex.h
#include "llthread.h" instead of the other way around. This makes LLMutex an
incomplete type within llthread.h, so move LLThread::lockData() and
unlockData() to the .cpp file. Similarly, remove llrefcount.h's #include
"llmutex.h" to break circularity; instead forward-declare LLMutex.
It turns out that a number of source files assumed that #include "llthread.h"
would get the definition for LLMutex. Sprinkle #include "llmutex.h" as needed.
In the SAFE_SSL code in llcorehttp/httpcommon.cpp, there's an ssl_thread_id()
callback that returns an unsigned long to the SSL library. When LLThread::
currentID() was U32, we could simply return that. But std::thread::id is very
deliberately opaque, and can't be reinterpret_cast to unsigned long.
Fortunately it can be hashed because std::hash is specialized with that type.

A level of preprocessor indirection lets us later change the implementation if
desired.

This also introduces LLContinueError for exceptions which should interrupt
some part of viewer processing (e.g. the current coroutine) but should attempt
to let the viewer session proceed.
Derive all existing viewer exception classes from LLException rather than from
std::runtime_error or std::logic_error.
Use BOOST_THROW_EXCEPTION() rather than plain 'throw' to enrich the thrown
exception with source file, line number and containing function.

replace llinfos, lldebugs, etc with new LL_INFOS(), LL_DEBUGS(), etc.

cleaning up build
moved most includes of windows.h to llwin32headers.h to disable min/max macros, etc
streamlined Time class and consolidated functionality in BlockTimer class
llfasttimer is no longer included via llstring.h, so had to add it manually in several places
