The general demuxing API uses bitstream filters to extract extradata
and the muxing API uses them in order to transform packets into
the format desired by the target format. Therefore FFStream contains
pointers to AVBSFContexts and lavf/internal.h includes lavc/bsf.h.
Yet actually, only a few files files are supposed to use these,
namely avformat.c, demux.c and mux.c. For all the other files,
it should be an opaque type that they should not touch and that
they need not know anything about. This can be achieved by not
including these headers and using the structs instead of the
corresponding typedefs.
This also forces translation units that really use the BSF API
themselves to include lavc/bsf.h directly instead of relying on
indirect inclusions (a few other files also use the BSF API;
they already abided by this).
Of course, it also avoids unnecessary rebuilds when bsf.h changes.

The general decoding API uses bitstream filters and an AVFifo
and therefore AVCodecInternal contains pointers to an AVBSFContext
and to an AVFifo and lavc/internal.h includes lavc/bsf.h and
lavu/fifo.h.
Yet actually, only two files are supposed to use these, namely
avcodec.c and (mainly) decode.c. For all the other files,
it should be an opaque type that they should not touch and that
they need not know anything about. This can be achieved by not
including these headers and using the structs instead of the
corresponding typedefs.
This also forces translation units that really use the BSF
and the FIFO APIs themselves to include the relevant headers
directly instead of relying on indirect inclusions (up until now,
even avcodec.c and decode.c relied on fifo.h to be included
by internal.h).
Of course, it also avoids unnecessary rebuilds when bsf.h or fifo.h
change.

Left shifts of signed types are UB unless the results fit
into the type. (Furthermore the value to be shifted need to be
nonnegative.)

Several encoders (roqvideo, svq1, snow, and the mpegvideo family)
currently call ff_get_buffer(). However this function is written
assuming it is called by a decoder. Though nothing has been obviously
broken by this until now, that may change in the future.
To avoid potential future issues, introduce a simple encode-specific
wrapper around avcodec_default_get_buffer2() and enforce its use in
encoders.
av_get_pix_fmt_name() is used in an ff_tlog(), which is only
compiled if TRACE is defined. Fixes a regression caused by
f2b79c5b85.

An auxiliary function for AVFormatContexts (mainly muxers,
but potentially (e.g. rtsp) also demuxers).

It is only used by demuxers (and it is generally demuxers
who have to translate format-specific IDs to stream indices).

They are also needed by the MMSH and MMST protocols and therefore
the file they are in is pulled in when these protocols are enabled
and used. By moving them to a separate file, linking statically to
libavformat while only using AVIO no longer pulls in all the
muxers/demuxers (and also no longer any AVCodecs when linking
statically to libavcodec).

It is not forbidden to call this with a muxer, so it is moved to
avformat.c and not demux_utils.c. ff_find_decoder(), which is used
by av_find_best_stream() is also moved as well, despite being even
more geared towards demuxers.

While it is clearly written with demuxers in mind,
it is not forbidden to call it with muxers, hence avformat.c
and not demux_utils.c.

It is not explicitly forbidden to call these functions with muxers
(although it is probably intended to be only called by demuxers;
av_guess_sample_aspect_ratio even says that "the stream aspect ratio
is set by the demuxer").

This file will contain the AVFormatContext-specific parts
that are used by both demuxers and muxers.

It is only used by demuxers (although it is hypothetically
possible that some day e.g. a protocol might need it, but
that is unlikely given that they don't deal with AVCodecParameters).
