(pinfo_fixup_after_fork): Delete.
(proc_waiter): Don't close vchild.hProcess here.  Do that when we are remove
the vchild from procs.  Save hProcess as pid_handle only on first reparent
operation.
(pinfo::wait): Don't set pid_handle here.
(pinfo::alert_parent): Always try to send signal.  If unsuccessful then close
and zero wr_proc_pipe.

zeroed on construction.

kept around so that the pid will not be reused.
* pinfo.h (_pinfo::pid_handle): Move.
(pinfo::pid_handle): to here.
* spawn.cc (spawn_guts): Create a pid_handle in cygheap prior to spawning to
ensure that the pid does not get reused during the lifetime of the "cygwin
pid".

* exceptions.cc (sig_handle_tty_stop): Use alert_parent to send "signals" to
parent.

exit code and use value from GetExitCodeProcess.  Reluctantly implement
__SIGREPARENT.
(pinfo::alert_parent): Define.

* spawn.cc (spawn_guts): Send reparent signal to parent on exec.  Always create
process in suspended state to avoid races.  Remove cygthread.h in favor of
cygtls.h throughout since cygtls now includes cygthread.h.  Eliminate
ppid_handle usage throughout.

myself->ppid_handle to see if we were started by a cygwin process.
* exceptions.cc (open_stackdumpfile): Ditto.
(handle_exceptions): Ditto.
(ctrl_c_handler): Ditto.
(sig_handle_tty_stop): Ditto.  Let parent send signal to itself on STOP.
(sigpacket::process): Comment out vfork test.

* fork.cc: Remove VFORK cruft.
(per_thread::set): Delete.
(fork_child): Remove perthread stuff.
(fork_parent): Remove obsolete subproc_init.  Accommodate new method for

(procs): New.
(my_parent_is_alive): Just check that the parent pid exists.
(mychild): Just use pinfo methods to determine if child is mine.
(proc_subproc): Revamp PROC_ADDCHILD to use pinfo::wait.  Remove
PROC_CHILDTERMINATED logic.  Use different method to remove processes from list
when SIGCHLD == SIG_IGN.
(proc_terminate): Gut.
(subproc_init): Delete.
(init_child_info): Remove setting of pppid_handle.
(checkstate): Revamp to only scan procs array.
(remove_proc): Rename from remove_zombie.  Don't close hProcess or pid_handle.

array.
(wait_subproc): Delete.
* sigproc.h: Remove obsolete EXIT_* defines.
