Exceptions were logged at level NOTICE while the stack traces were logged
at level DEBUG. That produced useless noise in the output with `-v5`
or `-v6`, where there were exception headings logged, but no details.
Fix that by placing the exceptions and traces at level DEBUG, but prefix
them with `TRACE:` for easy grepping.
Most of the events associated with BEESLOGTRACE either never happen,
or they are harmless (e.g. trying to open deleted files or subvols).
Reassign them to ordinary BEESLOGDEBUG, with one exception for
unrecognized Extent flags that should be debugged if any appear.

While investigating https://github.com/Zygo/bees/issues/282 I noticed that
we're doing at least one unnecessary extra copy of the functor in BEESTRACE.
Get rid of it with a const reference.

Since we're now using weak symbols for dodgy libc functions, we might
as well do it for gettid() too.
Use the ::gettid() global namespace and let libc override it.

libcrucible can deal with the Linux kernel and/or libc's thread name
limitations. No need to duplicate that work in bees.

In 15ab981d9e "bees: replace uncaught_exception(), deprecated in C++17",
uncaught_exception() was replaced with current_exception(); however,
current_exception() is only valid after an exception has been captured
by a catch block.
BeesTracer wants to know about exceptions _before_ they are caught,
so current_exception() is not useful here.
Instead, conditionally compile using uncaught_exception() or
uncaught_exceptions(), selected by C++ standard version, and make
bees stack traces work again.

This allows these components to be used by test executables without
pulling in all of bees, and more rapidly iterate their code.
