7297b17a84 tests/Makefile: Add auxiliary functions for transcode and stream_remux 
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.

202da3bf48 avcodec/mjpegenc: Don't unnecessarily grow buffer 
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.

c3047da646 avcodec/mpegvideo_enc: Fix unnecessary linear growth of buffer 
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.
