526cf6f291 Zoom: remove "stun_zoom" LRU cache
Since 070a0908b we are able to detect P2P calls directly from the packet
content, without any correlation among flows

Remove "zoom" cache (#2420)
This cache was added in b6b4967aa, when there was no real Zoom support.
With 63f349319, a proper identification of multimedia stream has been
added, making this cache quite useless: any improvements on Zoom
classification should be properly done in Zoom dissector.

Tested for some months with a few 10Gbits links of residential traffic: the
cache pretty much never returned a valid hit.

Remove workaround for TCP flows with multiple SYNs (#2421)
Deciding when a session starts and ends is responsability of the
applicationi (via its flow manager)i, not of the library.
BTW, the removed code is incomplete at beast

Merge RTP and RTCP logic (#2416)
Avoid code duplication between these two protocols.

We remove support for RTCP over TCP; it is quite rare to find this kind
of traffic and, more important, we have never had support for RTP
over TCP: we should try to add both detecion as follow-up.

Fix a message log in the LINE code
