* Add new function winpr_GetTickCount64NS for high resolution tick count with (up to) nanosecond resolution * Add new function winpr_GetUnixTimeNS for high resolution system time as nanoseconds since 1.1.1970 * Replace use of clock_gettime and gettimeofday in whole project with these new functions * Add new macros WINPR_TIME_NS_TO_* and WINPR_TIME_NS_REM_* to convert the nano second count to less resolution or get the remainder in the desired resolution
