This way it's easier for the programmer to look-up for a specific

This fixes the warning:
    libavformat/oggenc.c:75:7: warning: missing braces around initializer [-Wmissing-braces]

This fixes the warning:
    libavformat/avidec.c:81:5: warning: missing braces around initializer [-Wmissing-braces]

This fixes the two following warnings:
    libavdevice/alsa-audio-dec.c:62:26: warning: unused variable ‘sw_params’ [-Wunused-variable]
    libavdevice/alsa-audio-dec.c:109:15: warning: unused variable ‘st’ [-Wunused-variable]

This is consistent, allows custom handlers to print more info
(since they probably know about the AVFormatContext class
but not a demuxer-specific one) and also avoids issues due
to the class pointer being NULL for non-raw mpegts.

This will allow the incoming -timecode option to be handled in both
encoders (mpeg12enc in that case) and demuxers (dv, mxf, etc.).

It's called from avcodec_register() anyway, so there's no reason for it
to be public.

Move bit counting to the bit allocation function. Move exponent grouping to
after bit allocation. This will allow for adjustment of bandwidth parameters
during bit allocation without having to do exponent grouping multiple times.

Old version was based on lots of guesswork which had different hacks based on
32-bit version field instead of splitting it into major/minor/micro version.
RV2 picture header parser also had a few places where it deviated from binary
decoder.

The gradfun filter was already integrated natively in libavfilter.
Both filters issue the same output, and have a comparable performance.
