* exceptions.cc (signal_exit): Move captive process termintation...

(_cygtls::interrupt_setup): ...into here.
(sigpacket::process): Simplify setting of handler when have_execed.
(_cygtls::interrupt_setup): Don't call proc_subproc when we've execed.
* globals.cc (exit_states): Delete unneeded ES_EXEC_EXIT.
* pinfo.cc (pinfo::exit): Change debugging output.  Call proc_terminate rather
than the now-obsolete sigproc_terminate.  Don't set exit_state to ES_EXEC_EXIT.
Set exit_state to ES_FINAL later.
* sigproc.cc (sigproc_terminate): Delete function.
(wait_sig): Don't call proc_subproc if have_execed.
* sigproc.h (sigproc_terminate): Delete declaration.
* sync.h (lock_process::lock_process): Don't set exit_state to
ES_PROCESS_LOCKED.
(lock_process::operator LONG): Define.
