pixfmt: remove misleading and broken documentation

This was probably broken some time ago. The breakage is now part of the
ABI. For example, we have:

    AV_PIX_FMT_XYZ12BE
    AV_PIX_FMT_NV16
    AV_PIX_FMT_NV20LE

AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian
format it should be even. This must have been quite obvious when these
formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but
nobody cared or knew about this.

The future libavutil major bump will also break this additionally,
because disabling FF_API_VDPAU will remove an odd number of entries from
the middle of the enum.

Apparently it can happen that a mp3 file has junk data between id3 tag

(Two packets had the same timestamps, because the mp3 parser failed to
compute a frame duration.)

In this case, the junk consisted of 1044 bytes of zero, which
incidentally is the same size as normal mp3 frames in this stream. I
suspect the mp3 was edited with some tool which wiped the Xing/LAME
