Fix detection of WebDAV and Gnutella (over HTTP) Fix detection of z3950 Add two fuzzers to test `ndpi_memmem()` and `ndpi_strnstr()` Remove some dead code: * RTP: the same exact check is performed at the very beginning of the function * MQTT: use a better helper to exclude the protocol * Colletd: `ndpi_hostname_sni_set()` never fails Update pl7m code (fix a Use-of-uninitialized-value error)
