These protocols:
* have been addeded in the OpenDPI era
* have never been updated since then
* we don't have any pcap examples [*]
If (and it is a big if...) some of these protocols are still somehow
used and if someone is still interested in them, we can probably
re-add them starting from scratch (because the current detection
rules are probably outdated)
Protocols removed: DIRECT_DOWNLOAD_LINK, APPLEJUICE, DIRECTCONNECT,
OPENFT, FASTTRACK, SHOUTCAST, THUNDER, AYIYA, STEALTHNET, FIESTA,
FLORENSIA, AIMINI, SOPCAST
PPSTREAM dissector works (...) only on UDP.
[*]: with do have an AIMINI test pcap but it was some trivial http
traffic detected only by hostname matching, on domains no more
available...

We already performed exactly these lookups in the generic code to
populate `flow->guessed_protocol_id_by_ip`: use it!
This code probably needs a deeper review, since it is basicaly a simple
matching on ip + port.

Basically:
* "classification by-ip" (i.e. `flow->guessed_protocol_id_by_ip` is
NEVER returned in the protocol stack (i.e.
`flow->detected_protocol_stack[]`);
* if the application is interested into such information, it can access
`ndpi_protocol->protocol_by_ip` itself.
There are mainly 4 points in the code that set the "classification
by-ip" in the protocol stack: the generic `ndpi_set_detected_protocol()`/
`ndpi_detection_giveup()` functions and the HTTP/STUN dissectors.
In the unit tests output, a print about `ndpi_protocol->protocol_by_ip`
has been added for each flow: the huge diff of this commit is mainly due
to that.
Strictly speaking, this change is NOT an API/ABI breakage, but there are
important differences in the classification results. For examples:
* TLS flows without the initial handshake (or without a matching
SNI/certificate) are simply classified as `TLS`;
* similar for HTTP or QUIC flows;
* DNS flows without a matching request domain are simply classified as
`DNS`; we don't have `DNS/Google` anymore just because the server is
8.8.8.8 (that was an outrageous behaviour...);
* flows previusoly classified only "by-ip" are now classified as
`NDPI_PROTOCOL_UNKNOWN`.
See #1425 for other examples of why adding the "classification by-ip" in
the protocol stack is a bad idea.
Please, note that IPV6 is not supported :( (long standing issue in nDPI) i.e.
`ndpi_protocol->protocol_by_ip` wil be always `NDPI_PROTOCOL_UNKNOWN` for
IPv6 flows.
Define `NDPI_CONFIDENCE_MATCH_BY_IP` has been removed.

Avoid a double call of `ndpi_guess_host_protocol_id()`.
Some code paths work for ipv4/6 both
Remove some never used code.

Add detection over TCP and fix detection over IPv6.
Rename some variables since Stun dissector is no more "udp-centric".
Stun dissector should always classified the flow as `STUN` or
`STUN/Something`.
Don't touch `flow->guessed_host_protocol_id` field, which should be
always be related to "ip-classification" only.

If we have seen Application Data blocks in both directions, it means we
are after the handshake. At that point, extra dissection is useless.
Useful feature with TLS mid-sessions, i.e. sessions without initial
packets.

Add (basic) internal stats to the main data structures used by the
library; they might be usefull to check how effective these structures
are.
Add an option to `ndpiReader` to dump them; enabled by default in the
unit tests.
This new option enables/disables dumping of "num dissectors calls"
values, too (see b4cb14ec).

Skype detection over TCP has been completely disable since 659f75138 (3
years ago!).
Since that logic was too weak anyway, remove it.

If the extra callabck is not set, calling the extra dissection is only a
waste of resources...

* #1532 did fx TLS appdata detection only partially
* use flow->l4.tcp.tls.message.buffer_used instead of packet->payload
