Vladislav Yaroshchuk 027ac0cb51 target/i386/hvf: add rdmsr 35H MSR_CORE_THREAD_COUNT 
Some guests (ex. Darwin-XNU) can attemp to read this MSR to retrieve and
validate CPU topology comparing it to ACPI MADT content

MSR description from Intel Manual:
35H: MSR_CORE_THREAD_COUNT: Configured State of Enabled Processor Core
  Count and Logical Processor Count

Bits 15:0 THREAD_COUNT The number of logical processors that are
  currently enabled in the physical package

Bits 31:16 Core_COUNT The number of processor cores that are currently
  enabled in the physical package

Bits 63:32 Reserved

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.
