Tidy up the threading implementation The organization of the source files is now much more rational. Old experiments that didn't work out are now deleted. Naming of things like files is now more intuitive.

Apply even more fixups - Finish cleaning up the stdio unlocked APIs - Make __cxa_finalize() properly thread safe - Don't log locks if threads aren't being used - Add some more mutex guards to places using _mmi - Specific lock names now appear in the --ftrace logs - Fix mkdeps.com generating invalid Makefiles sometimes - Simplify and fix bugs in the test runner infrastructure - Fix issue where sometimes some functions wouldn't be logged

Implement pthread_atfork() If threads are being used, then fork() will now acquire and release and runtime locks so that fork() may be safely used from threads. This also makes vfork() thread safe, because pthread mutexes will do nothing when the process is a child of vfork(). More torture tests have been written to confirm this all works like a charm. Additionally: - Invent hexpcpy() api - Rename nsync_malloc_() to kmalloc() - Complete posix named semaphore implementation - Make pthread_create() asynchronous signal safe - Add rm, rmdir, and touch to command interpreter builtins - Invent sigisprecious() and modify sigset functions to use it - Add unit tests for posix_spawn() attributes and fix its bugs One unresolved problem is the reclaiming of *NSYNC waiter memory in the forked child processes, within apps which have threads waiting on locks

#ifdef _NOPL0
Make mutex calling code 10x tinier Calls to lock/unlock functions are now NOPs by default. The first time clone() is called, they get turned into CALL instructions. Doing this caused funcctions like fputc() to shrink from 85 bytes to 45+4 bytes. Since the ANSI solution of `(__threaded && lock())` inlines os much superfluous binary content into functions all over the place.
