This makes the code simpler to understand, though it results in an
unnecessary call to avcodec_find_decoder() if the stream won't be
decoded.

libmp3lame if available, ac3 otherwise.

libvorbis/libx264 for video if available, otherwise ac3/mpeg4.

Clarify with an example what the user should use instead of the
deprecated (and no longer working) -s/-pix_fmt options.

This fixes the situation when there are not enough entries in the index
(e.g. on initial seek there's only one index entry in the index) and index
search returns just the last known entry. That causes seeking function just to
seek there instead of trying harder to get at the requested position.

Currently for multichannel audio position for the last block position is
stored in index (and used for seeking), which is obviously not correct.

The current check on MMCO parameters prohibits a "max long term frame index
plus 1" of 16 (frame idx of 15) for the "set max long term frame index" MMCO.
Fix this off-by-one error to allow the full range of legal values.

Long term it would be nice to support error resilient reconfiguration
but right now setting this every frame does more harm than help.

By replacing
if (foo)
    <do stuff>

with
if (!foo)
    continue;
<do stuff>

It's equivalent to -g 0.

Allows us to get rid of forward InputStream declaration.
