Add a HAXM interface for QEMU API version
Add a HAXM interface so that QEMU can communicate its API version to HAXM.
With this, HAXM can keep better backward compatibility, for example, masking
of the new features if qemu does not support new features.

Check HAXM capability in QEMU
Checking HAXM capability to check if emulator can use HAXM virtalization.
Currently two possibility that HAXM not work. Firstly is VT/NX is not enabled
in the system, seconly is HAXM have used up the memory quota. See code comemnts
for the memry quota explaination.
Checking the capability in advance can give user more information that why HAXM
is not working and be more user friendly.

Fix the vmid issue in HAX
This patch is lost when submit the HAX patchset. Without this patch, only one emulator instance can use HAXM.

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.
