Remove `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` define from `fuzz/Makefile.am`; it is already included by the main configure script (when fuzzing). Add a knob to force disabling of AESNI optimizations: this way we can fuzz also no-aesni crypto code. Move CRC32 algorithm into the library. Add some fake traces to extend fuzzing coverage. Note that these traces are hand-made (via scapy/curl) and must not be used as "proof" that the dissectors are really able to identify this kind of traffic. Some small updates to some dissectors: CSGO: remove a wrong rule (never triggered, BTW). Any UDP packet starting with "VS01" will be classified as STEAM (see steam.c around line 111). Googling it, it seems right so. XBOX: XBOX only analyses UDP flows while HTTP only TCP ones; therefore that condition is false. RTP, STUN: removed useless "break"s Zattoo: `flow->zattoo_stage` is never set to any values greater or equal to 5, so these checks are never true. PPStream: `flow->l4.udp.ppstream_stage` is never read. Delete it. TeamSpeak: we check for `flow->packet_counter == 3` just above, so the following check `flow->packet_counter >= 3` is always false.
