1. config/output: Pick among all 8-bit and 10-bit formats …

   The usual 8-bit and 10-bit formats have a lot of variations:
   
           XRGB, XBGR, RGBX, BGRX, ARGB, ABGR, RGBA, BGRA
   
   A particular display is likely to support multiple of these, and as we
   need to allocate a buffer of a particular type to test it, we'd like to
   avoid doing too many unnecessary tests.
   
   If we go off on the assumption that a display device generally supports
   a subset of format variations but otherwise support each variation
   equally well - that is, if both RGB and BGR is supported, they will
   either both succeed or both fail at any given time - then instead of
   trying all formats, we can simply pick one supported format within each
   format group to try. For example, XBGR2101010 and XRGB8888.
   
   By being conservative in how many formats we try, we can aggressively
   expand the list of candidate formats to handle odd hardware.
   
   We can get rid of the the conservative aspect if KMS ever grows the
   ability to commit-test a buffer format without allocating the buffer
   first, allowing us to quickly test every format under the sun.
