thrkill(2), rolling the kill(2) syscall number with the ABI change to
avoid breaking binaries during during the transition.  thrkill(2) includes
a 'tcb' argument that eliminates the need for locking in pthread_kill()
and simplifies pthread_cancel().  Switch __stack_smash_handler() to use
thrkill(2) and explicitly unblock SIGABRT.

which results in tame() code placements being much more recognizeable.
tame() can be moved to unistd.h and does not need cpp symbols to turn the
bits on and off.  The resulting API is a bit unexpected, but simplifies the
mapping to enabling bits in the kernel substantially.

that should never have been installed.

What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time.  This makes the
tree safe for /usr/include/tzfile.h removal.  The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree.  Actual removal of tzfile.h is pending
a ports build.  Based on a diff from deraadt@

No actual change, but makes it easier to reuse the code elsewhere.

This hides the unavoidably cruddy sys/param.h namespace in some programs.
Little impact, because many programs are cruddy and still get it via
other includes.
