Since 070a0908b we are able to detect P2P calls directly from the packet
content, without any correlation among flows

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.

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

eDonkey is definitely not as used as >10 years ago, but it seems it is
still active.
While having a basic TCP support seems easy, identification over UDP doesn't
work and it is hard to do it rightly (packets might be only 2 bytes long):
remove it.

We are able to demultiplex RTP packets in STUN flows since 3608ab01b, at
least; no need to explicity call the RTP dissector

The basic idea is to have the following logic:
* pattern "DOMAIN" matches the domain itself (i.e exact match) *and* any
subdomains (i.e. "ANYTHING.DOMAIN")
* pattern "DOMAIN." matches *also* any strings for which is a prefix
[please, note that this kind of match is handy but it is quite
dangerous...]
* pattern "-DOMAIN" matches *also* any strings for which is a postfix
Examples:
* pattern "wikipedia.it":
* "wikipiedia.it" -> OK
* "foo.wikipedia.it -> OK
* "foowikipedia.it -> NO MATCH
* "wikipedia.it.com -> NO MATCH
* pattern "wikipedia.":
* "wikipedia.it" -> OK
* "foo.wikipedia.it -> OK
* "foowikipedia.it -> NO MATCH
* "wikipedia.it.com -> OK
* pattern "-wikipedia.it":
* "wikipedia.it" -> NO MATCH
* "foo.wikipedia.it -> NO MATCH
* "0001-wikipedia.it -> OK
* "foo.0001-wikipedia.it -> OK
Bottom line:
* exact match
* prefix with "." (always, implicit)
* prefix with "-" (only if esplicitly set)
* postfix with "." (only if esplicitly set)
That means that the patterns cannot start with '.' anymore.

Skype has been using standard protocols (STUN/ICE or TLS) for a long,
long time, now. Long gone are the days of Skype as a distribuited
protocol.
