	winsup/cygwin  : ChangeLog fhandler_disk_file.cc 
	                 fhandler_proc.cc fhandler_registry.cc hires.h 
	                 posix_ipc.cc resource.cc times.cc winsup.h 

Log message:
	Streamline time/times functionality.  Remove last remains of former
	Windows 9x compatibility.
	* fhandler_disk_file.cc (fhandler_base::fstat_helper): Drop now unneeded
	casts in calls to_timestruc_t.
	(fhandler_base::utimens_fs): Ditto for timespec_to_filetime.
	* fhandler_proc.cc (format_proc_stat): Ditto for to_time_t.
	* hires.h (class hires_ms): Remove unused member initime_ns.
	Remove declarations for timeGetTime_ns and prime.
	(hires_ms::uptime): Remove.
	* posix_ipc.cc (ipc_cond_timedwait): Ditto for timespec_to_filetime.
	* fhandler_registry.cc (fhandler_registry::fstat): Add cast.
	* resource.cc (fill_rusage): Call NtQueryInformationProcess rather than
	GetProcessTimes to deal with LARGE_INTEGER rather than FILETIME.
	* times.cc: Simplify time handling.  Throughout, use LARGE_INTEGER
	rather than FILETIME to simplify computations.  Throughout use
	{u}int64_t rather than {unsigned} long long.  Drop unneeded casts since
	NSPERSEC is 64 bit anyway.
	(systime_ns): Remove.
	(times): Call NtQuerySystemInformation to fetch boot time.  Call
	NtQueryInformationProcess rather than GetProcessTimes to deal with
	LARGE_INTEGER rather than FILETIME.  Call GetSystemTimeAsFileTime.
	(totimeval): Use constant 1000000 as in other functions.
	(time_t_to_filetime): Remove.
	(to_time_t): Change return type to time_t.
	(time_as_timestruc_t): Rename filetime to systime.
	(time): Ditto. Add cast.
	(hires_ns::nsecs): Fix return type cast.
	(hires_ms::timeGetTime_ns): Remove.
	(hires_ns::prime): Remove.
	(hires_ms::nsecs): Drop call to prime.  Call GetSystemTimeAsFileTime
	directly.  Subtract FACTOR here since it's the only function needing
	to do so.
	(minperiod): Cosmetically change to ULONG.
	(hires_ns::resolution): Fix return type cast.
	(hires_ms::resolution): Simplify, rely on NtQueryTimerResolution.
	* winsup.h: Align time related prototypes to above changes.
