* fuzz: extend fuzzing coverage (#2040)Ivan Nardi2023-07-11
| | | | | | | | | Some notes: * libinjection: according to https://github.com/libinjection/libinjection/issues/44, it seems NULL characters are valid in the input string; * RTP: `rtp_get_stream_type()` is called only for RTP packets; if you want to tell RTP from RTCP you should use `is_rtp_or_rtcp()`; * TLS: unnecessary check; we already make the same check just above, at the beginning of the `while` loop
