Igor Mammedov 87511341c3 add cpu_test_interrupt()/cpu_set_interrupt() helpers and use them tree wide The helpers form load-acquire/store-release pair and ensure that appropriate barriers are in place in case checks happen outside of BQL. Use them to replace open-coded checkers/setters across the code, to make sure that barriers are not missed. Helpers also make code a bit more readable.

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 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.
Removal of apic_page and hyperv-related functionality.
More relaxed use of bql_lock.
