Update mpv and ffmpeg

Major user-visible changes:
- OSD overhaul: remove some of the old OSD/sub options, which did not or
  barely worked, and add new options that work properly. The OSD font is
  now slightly more configureable as well. Look for options starting
  with --osd-... on the manpage.
- Image subtitles (like DVD/vobsubs) are rendered in color (disable with
  --sub-gray), and image subtitle placement is a bit more correct.
- The 's' key now takes screenshots with subtitles by default, and
  'shift+s' takes screenshots without subtitles. (Assumes you don't have
  a custom input.conf, or that your input.conf doesn't overrides these
  keys.)
- vo_xv can now take screenshots without OSD or subtitles natively. It
  doesn't framestep anymore in certain situations (e.g. playing with OSD
  on screen -> pausing -> toggling fullscreen -> vo_xv used to play one
  video frame and some audio to redraw the OSD).
  (Subtitle colors should be more correct as well and behave the same
  as with vo_opengl and vo_vdpau.)
- Show video title in window title instead on the console when
  streaming with libquvi.
- Encoding audio breakage with newer ffmpeg versions has been fixed.
