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.
