A heads up on this commit: if you're following -current and using any
perl modules that pull in threaded libraries from packages, such as
mysql/mariadb integration via DBD::mysql, then you may want to wait
the day or so until the ports package builds have caught up with the
change.  The perl in base built against libpthread.19.0 cannot load
the mysql.so shared object linked against libpthread.18.1

Log message:
Make pthread_atfork() track the DSO that called it like atexit() does,
unregistering callbacks if the DSO is unloaded.  Move the callback
handling from libpthread to libc, though libpthread still overrides the
inner call to handle locking and thread-library reinitialization.
Major version bump for both libc and libpthread.
