Also include it into the doxygen documentation

Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.

Additionally, this commit streamlines some spelling and appearances.

convert the comment that documents the metadata API to use
the doxygen markup

av_open_input_stream used to allow this, even though it makes no sense.
Make it just print a warning instead of failing, thus restoring
compatibility.

Note that avformat_open_input() will still reject this combination.

EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes
the stream position without resetting current_id.  The next
matroska_parse_cluster  fails due to calculation of incorrect pos.  So clear
current_id when avio_seek happens in matroska_read_seek.

This fixes this compilation warning, by making endptr a non-const
pointer, as required by strtol:
In function ‘udp_open’:
warning: passing argument 2 of ‘strtol’ from incompatible pointer type

ogg_save() copies streams[], but doesn't keep track of free()'ed
struct members. Thus, if in between a call to ogg_save() and
ogg_restore(), streams[].private was free()'ed, this would result
in a double free -> crash, which happened when e.g. playing small
chained ogg fragments.

These blocks don't report audio stream parameters and they are not needed
for decoding.

Calling Make from subdirectories is not supported and config.mak has
multiple inclusion guards anyway, so the top-level include is enough.

For a unicast udp stream to localhost:1234, currently
ffplay udp://:1234?localport=1234
works, but
ffplay udp://:1234
doesn't work.

This helps catching cases where the format string doesn't
match what is passed in, or injection bugs where user data
is passed in as format string.

This eliminates a warning about a set-but-unused variable.

This fourcc is used by the "mpegable AVC" codec and files encoded with
this codec decode correctly with our H.264 decoder.

av_get_bits_per_sample_fmt() is deprecated.

Needed for proper behaviour in our old API compatibility code.

It supports more convenient setting of AVOptions.

Deprecate the last remaining member of AVFormatParameters.

Add support for demuxer private options.

In this case, the string that was passed couldn't contain
user-defined data and thus there was no risk for injection
bugs, but it's safer this way, if we later change the
content of the options string.
