A few days ago ossfuzz stoped testing new FFmpeg as it run out of diskspacee

https://oss-fuzz-build-logs.storage.googleapis.com/index.html

An alternative would be to revert the API.

This changes for example
-rwxr-x--- 1 michael michael 144803654 May 14 12:54 tools/target_dec_ac3_fixed_fuzzer*
to
-rwxr-x--- 1 michael michael  30333852 May 14 12:51 tools/target_dec_ac3_fixed_fuzzer*

Which should massively decrease space requirements

My conversation from AVFormatContext->filename to AVFormatContext->url was
wrong in this case because get_chunk_filename uses filename as an output

This does require libmysofa with today's latest commit (https://github.com/hoene/libmysofa/commit/08f243d1ec35f6f794aedeb4b187d9f9353bdbc1).
They already had a pkg-config file, but the dependencies weren't setup right. Until now.

This should be included as `<lilv/lilv.h>`, same as is done in af_lv2.c.
Forcing the extra lilv-0 breaks platforms where the include dir is
`/usr/include/lilv/lilv.h` rather than
`/usr/include/lilv-0/lilv/lilv.h`.

The new include path works for both, because the `pkg-config --cflags`
includes `-I/usr/include/lilv-0`.

Fixes PMT parsing in some mpegts streams which contain
multiple tables within the PMT pid. Previously, the parser
assumed only one table was present in each packet, and discarded
the rest of the section data after attempting to parse the first
table.

A similar issue was documented in the BeyondTV software[1], which
helped me diagnose the same bug in the ffmpeg mpegts demuxer. I also
tried DVBInspector, libdvbpsi's dvbinfo, and tstools' tsinfo to
help debug. The former two properly read PMTs with multiple tables,
whereas the last has the same bug as ffmpeg.

I've created a minimal sample[2] which contains the combined PMT.
Here's what ffmpeg probe shows before and after this patch:

Before:

    Input #0, mpegts, from 'combined-pmt-tids.ts':
      Duration: 00:00:01.08, start: 4932.966167, bitrate: 741 kb/s
      Program 1
      No Program
        Stream #0:0[0xf9d]: Audio: ac3, 48000 Hz, mono, fltp, 96 kb/s
        Stream #0:1[0xf9b]: Audio: mp3, 0 channels, fltp
        Stream #0:2[0xf9c]: Unknown: none

After:

    Input #0, mpegts, from 'combined-pmt-tids.ts':
      Duration: 00:00:01.11, start: 4932.966167, bitrate: 718 kb/s
      Program 1
        Stream #0:0[0xf9b]: Video: mpeg2video ([2][0][0][0] / 0x0002), none(tv, top first), 29.97 fps, 29.97 tbr, 90k tbn, 90k tbc
        Stream #0:1[0xf9c](eng): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, 5.1(side), fltp, 384 kb/s
        Stream #0:2[0xf9d](spa): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, mono, fltp, 96 kb/s

With the patch, the PMT is parsed correctly so the streams are
created in the correct order, are associated with "Program 1",
and their codecs are set correctly.

This allows remuxing streams from one mpegts container to another,
without requiring avformat_find_stream_info() (or using `ffmpeg
