vo_vdpau: use new EOSD for OSD, remove support for old OSD format

This allows vo_vdpau to render OSD directly, without the indirection
through the old OSD API, and without the additional conversions.

Remove support for the old OSD format. Only the mplayer DVD subtitle
decoder still generates this format. Although the new OSD interface does
support this format, remove it from vo_vdpau. It would be relatively
hard to support it in the EOSD code, as it requires two surfaces. (These
two surfaces are blended on top of each other to emulate the mplayer OSD
format.) The correct way to implement direct support for DVD subs would
consist of adding a paletted image format of some sort. But even sd_lavc
converts paletted subtitle images to RGBA, so doing something special
just for DVD subs is not worth it.

This means the frontend (sub.c) converts the subtitles to RGBA if it
detects that vo_vdpau does not support them natively.
