cbf111059d avcodec/avcodec: Allow up to seven codec ids per parser
ff_pnm_parser and ff_vp3_parser already hit the current limit;
an addition to the former (to handle pfm) is planned.

9faf3f8bb0 avcodec/parser: Don't return pointer to stack buffer
When flushing, the parser receives a dummy buffer with padding
that lives on the stack of av_parser_parse2(). Certain parsers
(e.g. Dolby E) only analyze the input, but don't repack it. When
flushing, such parsers return a pointer to the stack buffer and
a size of 0. And this is also what av_parser_parse2() returns.

Fix this by always resetting poutbuf in case poutbuf_size is zero.

3735d55af3 avcodec/parser: move parsers list and related API to its own file
And add it to the CONFIGURABLE_COMPONENTS list in Makefile. This way, changes
to the new file will be tracked and the usual warning to suggest re-running
configure will be shown.

948f3c19a8 lavc: Make AVPacket.duration int64, and deprecate convergence_duration
Note that convergence_duration had another meaning, one which was in
practice never used. The only real use for it was a 64 bit replacement
for the duration field. It's better just to make duration 64 bits, and
to get rid of it.
