This patch adds to the configure script the code to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported.
