(from Ryan Johnson) * sigproc.cc (child_info_fork::abort): Rename from handle_failure. Change arguments to allow passing in a printf-like message. * winsup.h (api_fatal): Delete macro definition. (api_fatal): Redefine from __api_fatal. (vapi_fatal): Declare new function. * include/sys/strace.h (strace_vprintf): Define new macro. * ntdll.h (_SYSTEM_INFORMATION_CLASS): Add SystemHandleInformation.

(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. Document entire functionality of timeGetTime in case we need it. (hires_ms::resolution): Try a call to NtQueryTimerResolution to fetch current period. Fall back to heuristic if that fails. Cast to DWORD in assignments to minperiod. (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. Use status code from NtSetTimerResolution to compute errno. Convert period to ULONGLONG and store 100ns value to simplify code.

(fast_cwd_version): New shared variable to store FAST_CWD version used on the system. (find_fast_cwd_pointer): Rename from find_fast_cwd_pointers. Don't set global fast_cwd_ptr pointer here. Return pointer value instead. (find_fast_cwd): New function to set fast_cwd_ptr and fast_cwd_version. (cwdstuff::override_win32_cwd): Call find_fast_cwd from here. Check for fast_cwd_version to differ between old and new FAST_CWD structure. Check old_cwd for NULL to avoid SEGV. Don't set CWD if we have neitehr a valid fast_cwd_ptr, nor a valid CWD handle in the process parameter block. (cwdstuff::set): Create Win32 path taking /proc/sys paths into account. * spawn.cc (spawn_guts): Recode creating runpath. Also take /proc/sys paths into account.
