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.

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

Improve pledge() usability and consistency - We now kill the program on violations like OpenBSD - We now print a message explaining which promise is needed - This change also fixes a linkage bug with thread local storage - Your sigaction() handlers should now be more thread safe A new `__pledge_mode` global has been introduced to make pledge() more customizable on Linux. For example: __attribute__((__constructor__)) static void init(void) { __pledge_mode = SECCOMP_RET_ERRNO | EPERM; } Can be used to restore our old permissive pledge() behavior.
