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

Previously, "dar" and "a" were documented like "input display aspect
ratio", but their actual value was "in_w/in_h".
In order to avoid to break scripts which rely on the "a" variable, the
patch keeps the same semantics but fixes the corresponding docs, and
fixes the semantics of the recently added "dar" variable, which
now correctly expresses the input Display Aspect Ratio value as
"(inw_w/in_h)*sar".
The licence was changed from GPL to LGPL with explicit approval from
the original author.
