Log message:
	* cygwin/include/signal.h: Add copyright notice.
	* cygwin.din: Make clock SIGFE.  Add clock_gettime, sigwaitinfo, timer_create,
	timer_delete, timer_settime.
	* include/cygwin/version.h: Reflect above additions.
	* fork.cc (fork_child): Call fixup_timers_after_fork.
	* signal.cc (sigwait): Remove unused variable.
	* timer.cc: New file.
	(clock_gettime): Define new function.
	(timer_tracker): Define new struct used by timer functions.
	(timer_tracker::timer_tracker): New function.
	(to_us): New function.
	(timer_thread): New function.
	(timer_tracker::settime): New function.
	(timer_create): New function.
	(timer_settime): New function.
	(timer_delete): New function.
	(fixup_timers_after_fork): New function.
	* cygthread.cc: Bump thread count.
	* signal.cc (sigwaitinfo): Define new function.
	(sigwait): Redefine based on sigwaitinfo.
	* include/cygwin/signal.h (sigwaitinfo): Declare.
	(sigwait): Ditto.
	* dtable.cc (dtable::vfork_parent_restore): Avoid double close of ctty when
	ctty == ctty_on_hold.
	* cygtls.h (_threadinfo::threadkill): New element.
	(_threadinfo::set_threadkill): Declare new function.
	(_threadinfo::reset_threadkill): Declare new function.

	running process with #(*& Windows Me/9x.
	(initial_env): Try to initialize strace if uninitialized.
	* gendef: Don't zero signal if threadkill is set since that will happen in the
	called function.
	* signal.cc (sigwait): Ensure cleanup in error conditions.
	* sigproc.cc (sig_send): Clear packet mask storage.
	(wait_subproc): Fill in child exit code in siginfo_t structure.
	* thread.cc (pthread_kill): Set threadkill flag.
	* tlsoffsets.h: Regenerate.  Throughout, use siginfo_t to fill out all signal
	information for "kernel" signals.
	* cygtls.h (_threadinfo::set_siginfo): Declare new function.
	* cygtls.cc (_threadinfo::set_siginfo): Define new function.
	* dcrt0.cc (do_exit): Accommodate siginfo_t considerations.
	* exceptions.cc (handle_exceptions): Ditto.
	(sig_handle_tty_stop): Ditto.
	(ctrl_c_handler): Use killsys() to send signal.
