Add a new suboption to -vo xv and -vo xvmc that allows selection

of XVideo adaptor to be used (instead of default one, which is #0).

This is useful for example if you'd rather like to use the original
Overlay renderer of your GPU instead of the texture blitting engine
(which is usually default), which is number one cause of nasty
video tearing effects.
