New files to add HAX support

QEMU emulator interacts with the HAX kernel module. A HAX (Hardware-based Accelerated eXecution)
kernel module is required to use HAX support. Most guest instructions run in VMX non-root
(i.e. in hardware) mode and achieve near-native (relative to the host) performance.
QEMU still emulates PIO/MMIO instructions and non-PG (paging) mode operations.

HAX is supported only on Mac OS X and Windows hosts when Intel VT is present.
