1617d1a752 fftools/ffmpeg: pass subtitle decoder dimensions to sub2video 
Restores behavior from before 20cacfe493.
Eventually this should be handled similarly to audio/video - with a
filtergraph reset or a manual scaler.

88f80977eb fftools/ffmpeg: use AVFrame to pass subtitles from decoders to filters 
Allows to use the same buffering code for all media types. Will also be

e89a6d1089 fftools/ffmpeg_dec: move InputStream.prev_sub to Decoder

a45b9d35b9 fftools/ffmpeg: move fix_sub_duration_heartbeat() to ffmpeg_dec 
This way ffmpeg.c does not need to access InputStream.prev_sub and it
can be made private.

01897c1788 fftools/ffmpeg_dec: move decoding to a separate thread 
This is only a preparatory step to a fully threaded architecture and
does not yet make decoding truly parallel - the main thread will
currently submit a packet and wait until it has been fully processed by
the decoding thread before moving on. Decoder behavior as observed by
the rest of the program should remain unchanged. That will change in
future commits after encoders and filters are moved to threads and a
thread-aware scheduler is added.

5293adb1a7 fftools/ffmpeg: attach bits_per_raw_sample information to frames

7d4e00ccf0 fftools/ffmpeg_dec: stop using Decoder.pkt 
It is only used for flushing the subtitle decoder, so allocate a
dedicated packet for that.

Keep Decoder.pkt unused for now, it will be repurposed in future
commits.

174cb3accf fftools/ffmpeg_dec: remove pointless InputStream.hwaccel_retrieve_data 
It is always set to hwaccel_retrieve_data() from ffmpeg_hw.c, so that
function can just be called directly instead.

Make the function process just one input stream at a time and save an
indentation level. Also rename it to ist_add() to be consistent with an
analogous function in ffmpeg_mux_init.

Other than save a few bytes, it also has the benefit to show the
AV_OPT_TYPE_CONST value in help, e.g.,

  -profile           <int>        E..V....... Profile (from 0 to INT_MAX) (default 0)
     baseline        66           E..V....... Baseline Profile
