fuzz: some improvements and add two new fuzzers (#1881)
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.
