Vladislav Yaroshchuk 3b502b0e47 target/i386/hvf: add vmware-cpuid-freq cpu feature 
For `-accel hvf` cpu_x86_cpuid() is wrapped with hvf_cpu_x86_cpuid() to
add paravirtualization cpuid leaf 0x40000010
https://lkml.org/lkml/2008/10/1/246

Leaf 0x40000010, Timing Information:
EAX: (Virtual) TSC frequency in kHz.
EBX: (Virtual) Bus (local apic timer) frequency in kHz.
ECX, EDX: RESERVED (Per above, reserved fields are set to zero).

On macOS TSC and APIC Bus frequencies can be readed by sysctl call with
names `machdep.tsc.frequency` and `hw.busfrequency`

This options is required for Darwin-XNU guest to be synchronized with
host

Leaf 0x40000000 not exposes HVF leaving hypervisor signature empty

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.
