This avoids having to do one pass to calculate the full length to allocate
followed by a second pass to actually append values.

It also adds the missing depenencies on the file and pipe protocols
and the framecrc muxer.

Tests using the transcode and stream_remux functions have some common
requirements (namely the file and pipe protocols as well as the framecrc
muxer) and also other commonalities: The create a file and read it
immediately afterwards, so that they typically rely on a corresponding
muxer+demuxer pair which typically shares the same name; for transcode
(if it does not use stream copy) the same is true for encoders and
decoders. This means that using special Makefile-functions instead
of the general ALLYES is worthwhile. This commit adds such functions.
These functions allow to add arbitrary CONFIG-checks on top of the
aforementioned ones in order to satisfy special needs (for e.g. parsers,
filters) that several intended users have.

The size of the ICC chunk has already been accounted for when
the packet's buffer was initially set in ff_mpv_encode_picture()
and the header (including the ICC chunk) has already been written
at this point.

It is a remnant of the old way for user-supplied buffers;
it is always-true since 93016f5d1d.

If one encodes MJPEG with a single slice and uses input with
AV_FRAME_DATA_ICC_PROFILE side data, the current allocation code
in ff_mpv_encode_picture() will always increase the size of the
temporary buffer used for allocating packets by the size needed
for to write the ICC chunk even when the current buffer is actually
large enough. This commit fixes this.

MJPEG is the only mpegvideo-based encoder making use of it.
Fixes linking failures in case mpegvideo_enc.c is compiled
with AMV, LJPEG and MJPEG encoders disabled.

PATH_MAX is posix. Some compilers (MSVC) don't define this
thus failing to compile the ipfsgateway file.
Defining it fixes the compile.

It works, but it is not documented to work.

This field is currently used by checks
- skipping packets before the first keyframe
- skipping packets before start time
to test whether any packets have been output already. But since
frame_number is incremented after the bitstream filters are applied
(which may involve delay), this use is incorrect. The keyframe check
works around this by adding an extra flag, the start-time check does
not.
Simplify both checks by replacing the seen_kf flag with a flag tracking
whether any packets have been output by do_streamcopy().
