(_pinfo::initialize_lock): Ditto.
* pinfo.cc (set_myself): Use initialize_lock method to initialize myself lock.
Set "exec" fields in _pinfo to zero to indicate that we've started
successfully. Set start time here when appropriate.
(_pinfo::commune_send): Use pinfo lock/unlock methods.
(proc_waiter): Remove special case for non-cywin processes. Reinstitute
handling for PID_NOCLDSTOP.
* sigproc.cc (proc_subproc): Set proper EAGAIN errno when process table is
filled.
(sig_send): Use exec_* fields from _pinfo for sending signals if the the _pinfo
sendsig never materializes.
(child_info::child_info): New constructor, renamed from init_child_info.
Zeroes child_info structure and sets appropriate fields in structure based on
chtype.
(child_info::~child_info): New destructor. Closes subproc_ready if it exists.
(child_info_fork::child_info_fork): New constructor.
(child_info_spawn::child_info_spawn): New constructor.
(child_info::ready): New function. Signals parent when child is ready.
(child_info::sync): New function. Wait for child to signal us or process to
die.
(remove_proc): Remove closing of hProcess since this should now be handled
shortly after process creation.
* spawn.cc (spawn_guts): Use child_info_spawn constructor rather than
init_child_info. Save exec_sendsig and exec_dwProcessId in execing _pinfo.
Rely on child_info constructor to properly set parent_wr_proc_pipe in ciresrv.
Revert to previous determination on whether to start a process in suspended
mode. Remove reparenting stuff. Just keep a stub around if starting a
non-cygwin process.
