[libvirt] [PATCH] qemu: Allow setting boot menu on/off

Add a new element to the <os> block: <bootmenu enable="yes|no"/> Which maps to -boot,menu=on|off on the QEMU command line. I decided to use an explicit 'enable' attribute rather than just make the bootmenu element boolean. This allows us to treat lack of a bootmenu element as 'use hypervisor default'.
