AVOutputFormat has default codecs for audio, video and subtitle
and often these are the only codecs of this type allowed.
So add a flag to AVOutputFormat so that this can be checked generically.

More exactly: Not more than one stream of each type for which
a default codec (i.e. AVOutputFormat.(audio|video|subtitle)_codec)
is set; for those types for which no such codec is set (or for
which no designated default codec in AVOutputFormat exists at all)
no streams are permitted.
Given that with this flag set the default codecs become more important,
they are now set explicitly to AV_CODEC_ID_NONE for "unset";
the earlier code relied on AV_CODEC_ID_NONE being equal to zero,
so that default static initialization set it accordingly;
but this is not how one is supposed to use an enum.

This commit does for AVInputFormat what commit
59c9dc82f4 did for AVOutputFormat:
It adds a new type FFInputFormat, moves all the internals
of AVInputFormat to it and adds a now reduced AVInputFormat
as first member.
This does not affect/improve extensibility of both public
or private fields for demuxers (it is still a mess due to lavd).
This is possible since 50f34172e0
(which removed the last usage of an internal field of AVInputFormat
in fftools).
(Hint: tools/probetest.c accesses the internals of FFInputFormat
as well, but given that it is a testing tool this is not considered
a problem.)

Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

It only uses an AVIOContext and an AVBPrint.
When doing so, it turned out that several non-users of
ff_read_line_to_bprint_overwrite() and ff_bprint_to_codecpar_extradata()
relied on libavformat/internal.h to include bprint.h or avstring.h
for them. In order to avoid a repeat of this and in order to reduce
unnecessary dependencies, a forward declaration of struct AVBPrint is
used instead of including bprint.h.

Enforcing num_chunks == 1 only makes sense when demuxing from an ASF
file. When embedded in a BRP file, an ASF stream can have multiple chunks.

Version 1.1 (FX Fighter) files all have a sample rate of 44100
in the header, but only play back correctly at 22050.
Force the sample rate to 22050 when reading, and restrict it
when muxing.

It has no bearing on structure. Determined by looking at the ASF
files from several Argonaut games:
- FX Fighter,
- Croc,
- Croc 2,
- The Emperor's New Groove, and
- Disney's Aladdin in Nasira's Revenge
The only versions that appear are 1.1, 1.2, and 2.1, and their
structure is identical.
