[RFC 0/2] qemu-sem-posix: use monotonic clock instead

[Longpeng(Mike)]

The qemu_sem_timedwait() uses system time as default, it would be affected by
changes to the system time. In the real scenario, the time that goes faster or
slower is a common case and the NTP service could help us to sync time
periodically.

This patchset uses monotonic clock instead of the realtime clock, this could
make sure we would not be affected by the system time anymore.

Longpeng (Mike) (2):
  sem-posix: remove the posix semaphore support
  sem-posix: use monotonic clock instead
