Where possible, CLOCK_MONOTONIC_RAW should be implemented in terms or
rdtscp. It will provide the highest accuracy time source tha

These two assessments are partly just wrong, partly fail to see the

This replaces all of the QEMU timer code with GHRTimer, dramatically simplifying
time keeping in QEMU while making it possible to use QEMUTimer code outside of
the main loop. The later is critical to building unit tests.
This is an RFC because I'm sure this breaks things as it changes things. QE
