The handling of audio stream numbering was handled in the stream
selection property was a total mess. The most important issue was
confusion between values used as index for demuxer->audio_streams[]
array (consistently stored in demuxer->audio->id) and values stored
in sh_audio->aid and used as "-aid N" option values. Now demuxer audio
switch control functions and demuxer_switch_audio() are supposed to
return the new value for the "-aid" option (internal MPEG demuxers
still don't; the demuxer requirement could perhaps be dropped as it
can be easily calculated afterwards). That is also the value
returned for the "switch_audio" property. The main changes are:
- Make command.c mp_property_audio() consistently use and return the
"-aid" values. Before it used that as input but the array index as
output, with extra mess related to demuxer_switch_audio() return
value. Don't modify the audio_id option field any more.
- Make demuxer_switch_audio() always return "-aid" values (like it
takes as input). There are two changes for this: picking this
return value in case the demuxer doesn't support switching, and
overriding demuxer return value (for internal MPEG demuxers).
- Make demux_lavf return "-aid" values from DEMUXER_CTRL_SWITCH_AUDIO
code. This isn't actually necessary because of the override part
above.
Here's some history of the relevant behavior that I looked up:
* For most demuxers array index and "-aid" values are the same. At
least demux_mkv, (some of?) the internal MPEG demuxers and demux_ogg
have differed for a long time. demux_ogg doesn't matter because it
doesn't support stream switching.
* Old code seemed to assume that demuxer_switch_audio() return value was
array index, but this wasn't true at least for demux_mkv.
* In svn r19951 reimar mostly removed use of the return value.
* In r20162 ptt added mp_property_audio(). This set the global
audio_id variable (-aid option value) to the return value of
demuxer_switch_audio() and treated the global as the persistent
value of the property, apparently assuming that it would be set to
the "-aid" value, not array index. This was false for internal
MPEG.
* In r30124 reimar changed the property code so that even though it
still modified the option value it didn't use that as the value of
the property any more; instead it incorrectly used the array index.
This meant that for demux_mkv the return value didn't match -aid any
more (though input still did, so setting the property and querying
it didn't match as they used different value systems).
* In r31129 aurel made demux_lavf changes that resulted in its -aid
and array index values no longer matching either. He didn't change
the return value from audio switch when changing -aid, so it now
matched array index only. The latter part didn't cause additional
problems from r20162 though because either choice would have been
broken anyway after r30124 as long as they weren't the same value.
Before "-chapter 1" did nothing even if the first chapter didn't start
at the beginning of file. Fix it.
Before all chapter property commands (including chapter seek keys)
failed if the current playback position was before the start of the
first chapter. Now they'll work. Relative chapter seeks will go to the
first chapter (even if that's in the wrong direction for backward
seeks).
Only try to use the dvd/dvdnav stream seek hack with those stream
types. Generally demuxers can not be expected to cope with the stream
suddenly seeking under them. In principle it would be more correct to
make the test demuxer-based (instead of assuming that using stream
seeks in this manner is OK with whatever demuxer that will be used
with these streams), but that'd be more work.
Move code for resetting decoders after seeks, chapter seeks and angle
changes out of demuxer.c. This functionality belongs on a higher
level; the demux layer can't always know what kind of reinitialization
is required.
These functions return void*, which is compatible with any pointer,
so there is no need for casts.

Change the demuxer_add_attachment() and demuxer_add_chapter()
functions to take a length argument for various name strings, so those
strings do not need to be 0-terminated. This will make it easier to
directly pass demuxed data without first making a copy just to add
0-termination. Also allocate the struct demuxer data structures for
attachments and chapters with talloc.

Parsing can be done at the demuxer stage (currently disabled) or at the decoder

Reimar's previous commit ("Unbreak the demuxer-specific code in
video.c with e.g.") added the new field "non_interleaved" in
demux_stream structs, but this field was not initialized anywhere.
Under suitable circumstances this could cause a "Too many
video/audio packets in the buffer" error and failing playback. Fix
the problem by cleaning up the code that creates new instances of the
struct. Now fields will be initialized to 0 by default.
