We need at least a few bits of entropy to determine the start index of each queue, in order to let filters run in parallel as much as possible, and rand() is not thread safe and disrupts any external API's usage of rand, so instead replace it with av_get_random_seed. While it has more overhead than rand, we only run it once per filter upon init.

Up until now, the HLS muxer uses av_strtok() to split an input string controlling parameters of the VariantStreams and then duplicates parts of this string containing parameters such as the language or the name of the VariantStream. But these parts are proper zero-terminated strings of their own that are never modified lateron, so one can simply use the substring as-is without creating a copy. This commit implements this. The same also happened for the string controlling the closed caption groups. Furthermore, add const to indicate that the pointers to these substrings are not used to modify them and also to indicate that these strings are not allocated on their own.

Up until now, the HLS muxer duplicated a string for every VariantStream, although neither the original nor the copies are ever modified. So use the original directly and stop copying. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

high resolutions with only small blocks appear to be rather slow with the fuzzer + sanitizers. A solution which makes this run faster is welcome.

The old resync logic had some bugs, for example the packet size could stuck into 192 bytes, because pos47_full was not updated for every packet, and for unseekable inputs the resync logic simply skipped some 0x47 sync bytes, therefore the calculated distance between sync bytes was a multiple of 188 bytes. AVIO only buffers a single packet (for UDP/mpegts, that usually means 1316 bytes), so for every ten consecutive 188-byte MPEGTS packets there was always a seek failure, and that caused the old code to not find the 188 byte pattern across 10 consecutive packets. This patch changes the custom logic to the one which is used when probing to determine the packet size. This was already proposed as a FIXME a long time ago...

then ff_h264_free_tables() and h264_decode_end() can be removed in h264_decode_init() if it's failed.
