Xen devel - Dec 2007 - PATCH: Add QEMU BIOS menu for choosing boot device

The attached patch implements a mini BIOS menu for choosing a non-default
boot device. When a guest starts it''ll display 

   ''Press F10 to select boot device''

And wait 3 seconds, before continuing with the normal boot device. If they
press the F10 key, a menu is shown allowing a choice between floppy,
harddisk, cdrom and network (PXE).

I can''t take credit for this originally - Jeremy Katz wrote it for KVM,
I merely re-diffed the patch to work against Xen''s QEMU/BIOS code tree.
It has been tested in Fedora successfully against 3.1.x and 3.2.x

If more than one boot device has been selected, the currently selected
number displayed in the menu is wrong.
The tiny patch I am attaching makes sure that only the first boot device
is considered.
The patch has to be applied on top of the original patch.
