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.
