SL-10297: Eliminate llerror.cpp's Globals::messageStream and bool.

Instead of a single std::ostringstream instance shared by all callers, even
those on different threads, make each of the relevant lllog_test_() and
llcallstacks macros instantiate independent (stack) std::ostringstream
objects. lllog_test_() is called by LL_DEBUGS(), LLINFOS(), LL_WARNS(),
LL_ERRS(), LL_VLOGS() et al.

Eliminate LLError::Log::out(), whose sole function was to arbitrate use of
that shared std::ostringstream. Amusingly, if the lock couldn't be locked or
if messageStreamInUse was set, out() would allocate a new (heap!)
std::ostringstream anyway, which would then have to be freed by flush().

Make both LLError::Log::flush() overloads accept const std::ostringstream&.
Make LL_ENDL pass the local _out instance. This eliminates the need to check
whether the passed std::ostringstream* references the shared instance and
(if so) reset it or (if not) delete it.

Make LLError::LLCallStacks::insert() accept the local _out instance as non-
const std::ostream&, rather than acquiring and returning std::ostringstream*.
Make end() accept the local instance as const std::ostringstream&.
