Cameron Esfahani 9fedbbeeee hvf: remove TSC synchronization code because it isn't fully complete 
The existing code in QEMU's HVF support to attempt to synchronize TSC
across multiple cores is not sufficient.  TSC value on other cores
can go backwards.  Until implementation is fixed, remove calls to
hv_vm_sync_tsc().  Pass through TSC to guest OS.

OS X Hypervisor.framework support in QEMU

These sources (and ../hvf-all.c) are adapted from Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor) (last known location: https://github.com/veertuinc/vdhh) with some minor changes, the most significant of which were:

  1. Adapt to our current QEMU's CPUState structure and address_space_rw API; many struct members have been moved around (emulated x86 state, xsave_buf) due to historical differences + QEMU needing to handle more emulation targets.
  2. Removal of apic_page and hyperv-related functionality.
  3. More relaxed use of qemu_mutex_lock_iothread.
