This patch adds a videoram parameter (4MB is the default) to pv guests
too: if the pv guest is actually a stubdomain then the videoram size is
added to the initial required available memory.
This way there is no risk that a stubdom fails to populate the videoram
because the RAM freed for the videoram by dom0 has already been used to
create the stubdom.
