Modified files:
	winsup/cygwin  : autoload.cc hires.h ntdll.h path.cc times.cc 

Log message:
	* autoload.cc (winmm): Rremove time functions.  Don't treat
	unloadable wave functions as fatal.
	* hires.h (hires_ms::timeGetTime_ns): New private method.
	(hires_ms::dmsecs): Call timeGetTime_ns here.
	* ntdll.h (struct _KSYSTEM_TIME): Define.
	(KUSER_SHARED_DATA): Redefine to allow access to InterruptTime.
	(SharedUserData): Define here.
	(NtQueryTimerResolution): Declare.
	(NtSetTimerResolution): Declare.
	* path.cc (SharedUserData): Move to ntdll.h.
	* times.cc (hires_ms::timeGetTime_ns): New private method.
	Use throughout instead of timeGetTime.
	(hires_ms::resolution): Try a call to NtQueryTimerResolution
	to fetch current period.  Fall back to heuristic if that fails.
	(clock_setres): Align period to possible values per a call to
	NtQueryTimerResolution.  Explain why.  Replace calls to
	timeBeginPeriod and timeEndPeriod with underlying call to
	NtSetTimerResolution.
