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 Update documentation accordingly. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5335 c046a42c-6fe2-441c-8c8c-71466251a162
