* Add The Elder Scrolls Online support
* Use ndpi_memmem instead of memmem from libc
* Add protocol description
* Change selection bitmask to V4_V6
* Update protocols.rst
Enable parsing of Mapped-Address attribute for all STUN flows: that
means that STUN classification might require more packets.
Add a configuration knob to enable/disable this feature.
Note that we can have (any) STUN metadata also for flows *not*
classified as STUN (because of DTLS).
Add support for ipv6.
Restore the correct extra dissection logic for Telegram flows.
Tradeoff between key comparison efficiency (i.e. no `memcmp`) and key
length.
At least in the ipv4 cases, we have no more different entries with the
same key.
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.

Follow up of 31c706c3db and
75485e177c.
Allow fast classification by ip, but give time to other dissectors to
kick in (for example, the TLS code for the Telegram Web flows).
Even if we don't classify it anymore at the very first packet (i.e. SYN)
we fully classify Telegram traffic at the first packet with payload, as
*any* other protocol.
This way, we always have the proper category, the proper confidence
for the UDP flows and we don't overwrite previous classifications (TLS
or ICMP)
Remove old and stale identification logic for TCP flows
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.
