Hypervisor.framework Support for QEMU

The idea of the project is to add support for macOS’s native hypervisor through the Hypervisor.framework API. This API exposes to user applications the processor's Virtual-Machine Extensions (VMX), which allows fast and transparent virtualization in user space by allowing guest software to execute directly and unmodified on the processor, avoiding costly and complicated emulation. Hypervisor.framework is part of Mac OS frameworks since OS X Yosemite (version 10.10).
