#13334 (Improved Video timing and Synchronization) breaks macOS compilation

Guys,
FYI
Pls see error below…

Some googling tells that TIMER_ABSTIME and clock_nanosleep are not supported on Mac OS but just on Linux.

Maybe good pointer is here: https://code.i-harness.com/en/q/4ed8a5 ?

I see some internet articles saying that clock_gettime and
clock_nanosleep are not supported in MACOS. Your compile shows an error
in 'TIMER_ABSTIME'. I cannot find any MACOS documentation and I have no
way of testing it, so I will create some alternative code that uses only
QT functions and will be used when TIMER_ABSTIME is not defined.
Playback may be less smooth than the code that uses the linux functions.

Peter

Please try the attached patch. This changes the avsync2 to use QT
timers, including for Linux. It does not seem to make any difference to
playback and will be better supported.
