In order to replace QXL with Standard_VGA in small steps, bisectably,
first just introduce the Standard_VGA constructor.
Extend the string_of_video function at once ("stdvga"). The value returned
by this function is only used for debug logging (indirectly, via the
string_of_guestcaps and string_of_requested_guestcaps functions).
The virt-v2v build flags turn "non-exhaustive pattern matching" warnings
into errors. Match the new "Standard_VGA" constructor with a constant
false assertion wherever an expression of type "guestcaps_video_type" is
matched, in order to make this patch bisectable. These assertions will be
gradually replaced with actual logic in the rest of this patch set.
