The hooks we have that call us after reset, init and loadvm really all just want to say "The reference of all register state is in the QEMU vcpu struct, please push it". We already have a working pushing mechanism though called cpu->vcpu_dirty, so we can just reuse that for all of the above, syncing state properly the next time we actually execute a vCPU. This fixes PSCI resets on ARM, as they modify CPU state even after the post init call has completed, but before we execute the vCPU again. To also make the scheme work for x86, we have to make sure we don't move stale eflags into our env when the vcpu state is dirty.

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:
- Adapt to our current QEMU's
CPUState
structure andaddress_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. - Removal of
apic_page
and hyperv-related functionality. - More relaxed use of
qemu_mutex_lock_iothread
.
