Not all "sub-playlists" are variant playlists (containing the same
content with a different bitrate, etc) in the current version of the HLS
specification. They can now also be alternative renditions, containing
e.g. alternative audio tracks etc.

Decouple playlists from variants to prepare for handling the new
features.

Some rare bink files include unused bytes between the frame table index
and first frame data.

Fixes ticket #3266.

This patch has also been tested with non-seekable protocols.

Replace "The segmenter muxer" with "This muxer". The "segmenter muxer"
was never defined before, and thus it is a slightly ambiguous term.

In particular, reference segment muxer and clarify difference between
segment filename number and playlist sequence number.

Should fix trac ticket #2601.

These are not supported by all compilers (gcc 2.95 but also older SPARC
compilers, see gcc bug #33304 for example), and there is no real need for them.
One use of this feature remains in libavdevice/v4l2.c which can't be
replaced quite as easily.

Add ff_id3v2_read_dict() for parsing without AVFormatContext, but
instead with AVIOContext and AVDictionary.

AVFormatContext is still used for logging, if available.

Chapter parsing is the only non-logging functionality that actually
needs AVFormatContext, and AFAICS it should be modified to write the
data to ID3v2ExtraMeta first, from where it can be implanted to
AVFormatContext by a separate function (like it is done with
read_apic() and ff_id3v2_parse_apic()). That is outside the scope of
this patch, though.
