New syntax contains an optional stream type, allowing to refer to n-th
stream of specific type.

Omitting stream number now maps all streams of the given type.

They are confusing, irregular and redundant -- -map already contains all
the information.  Stream maps can now be parsed in opt_output_file().

Add a more user-friendly default behavior in case no maps are present.

Breaks -programid for now, but it never worked properly anyway. A better
solution will be written soon.

The output of the x264 commandline tool contains the most uptodate
description of the possible values for the -preset, -tune and -profile
options.

Before, it took an input and output file index, now it only takes an
input file and applies to the next output file.

Stream/chapter/program specification is now part of the option name and
the delimiter was changed from ',' to ':' to be consistent with the
similar feature for AVOptions.

This is consistent with how all the other options work.

It will be further developed with a few incompatible changes.

ffmpeg.c will stay as is for some time, so any scripts using it won't be
broken.

Use 'auto' as the default value.

This removes all valgrind-reported invalid writes with one
specific test file.

This is faster than using the clip_coefficients() function. Also,
clipping the coordinates before determining reuse is better since it
will compare coordinates that are closer to their final encoded values.

bits_per_raw_sample is used in video as well, where sample_fmt is not used.

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

channel.

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.
