* cygerrno.h (geterrno_from_nt_status): Declare.

Browse Source 
* errno.cc (geterrno_from_nt_status): Define.
	* flock.cc: Fix copyright dates.
	* ntdll.h (enum _TIMER_TYPE): Define.
	(PTIMER_APC_ROUTINE): Define.
	(NtCancelTimer): Declare.
	(NtCreateTimer): Declare.
	(NtSetTimer): Declare.
	* posix_ipc.cc (ipc_cond_timedwait): Rewrite to make interruptible and
	restartable.  Call pthread_testcancel in case of timeout to enable
	pthread_cancel on waiting thread.  Replace WFMO timeout with waiting
	for a waitable timer.  Explain why.  Replace single call to WFMO with
	two calls, one for the event, one for the mutex.  Don't lock mutex in
	case of error.
	(ipc_cond_signal): Make void function.
	(ipc_cond_close): Ditto.
	(_mq_send): Immediately return -1 in case of error from
	ipc_cond_timedwait.
	(_mq_receive): Ditto.
