* 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.
* dcrt0.cc (dcrt0_1): Call here so that it will be possible to attach to
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.
(sigpacket::process): Rename from sig_handle. Use siginfo_t field from
sigpacket for everything.
(tty_min::kill_pgrp): Accommodate siginfo_t considerations.
(fhandler_termios::bg_check): Ditto.
* fhandler_tty.cc (fhandler_tty_slave::ioctl): Use killsys() to send signal.
* signal.cc (kill_worker): Rewrite to use siginfo_t second argument.
(kill_pgrp): Ditto.
(kill0): Define new function pulled from kill().
(kill): Rewrite as frontend to kill0.
(killsys): Define new function.
* sigproc.cc (sigelem): Eliminate.
(sigpacket): Move to sigproc.h. Subsume sigelem.
(pending_signals): Use sigpacket rather than sigelem for everything.
(sig_clear): Ditto.
(wait_sig): Ditto.
(sig_send): Rewrite to use siginfo_t argument.
(sig_send): New function wratpper to sig_send with siginfo_t argument.
(wait_subproc): Accommodate siginfo_t considerations.
* thread.cc (pthread_kill): Ditto.
* sigproc.h (sigpacket): Move here.
(sigpacket::process): Declare "new" function.
(sig_handle): Eliminate declaration.
(sig_send): Declare with new paramaters.
(killsys): Declare new function.
(kill_pgrp): Declare.
* winsup.h: Move some signal-specific stuff to sigproc.h.
* include/cygwin/signal.h: Tweak some siginfo_t stuff.
