 Change the way video graphics adapter is selected

 Instead of having (current)three command line switches -std-vga,
 -cirrusvga and -vmwarevga, provide one -vga switch which takes
 an argument, so that:
 qemu -std-vga   becomes qemu -vga std
 qemu -cirrusvga becomes qemu -vga cirrus
 qemu -vmwarevga becomes qemu -vga vmware

I'd prefer a more generic syntax, like -drive options:
-displayhw model=vga,type=std
-displayhw model=vga,type=std
-displayhw model=vga,type=std
-displayhw model=tcx,type=hardwarecursor

I think this would quickly rat hole since it requires rewriting a huge amount of code.

Then this option would be useful for non-VGA targets. I don't see -vga
xxx as an improvement over -xxx-vga.

If the next steps are creating a mechanism to register VGA hw emulation, then I think this is a step in the right direction.

I think we have to get to a place where most hardware devices are registered within a generic frame work before we start trying to expose that to the user.

Also, there should be compatibility support for previous syntax, like
-cdrom or -hda implies some -drive options.
