Changes to existing files to add HAX support

HAX (Hardware-based Accelerated eXecution) employes hardware virtualization
technology to boost performance of the Android emulator on Mac OS X or Windows
hosts.
This changeset includes the changes required to the existing files. To pass
the compilation, hax.h is added, but CONFIG_HAX is disabled so that no
real changes added.
