Tls out of order (#2561)
* Revert "Added fix for handling Server Hello before CLient Hello"

This reverts commit eb15b22e77.

* TLS: add some tests with unidirectional traffic

* TLS: another attempt to process CH received after the SH

Obviously, we will process unidirectional traffic longer, because we are
now waiting for messages in both directions

FPC: add DPI information (#2514)

526cf6f291 Zoom: remove "stun_zoom" LRU cache

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.

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

eDonkey: improve/update classification (#2410)
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.

Remove PPStream protocol and add iQIYI (#2403)
P2P video player PPStream was discontinued shortly after the purchase of PPS.tv by Baidu (iQIYI) on 2013 (see https://www.techinasia.com/report-baidu-acquires-video-rival-pps)
So we remove the old `NDPI_PROTOCOL_PPSTREAM` logic and add `NDPI_PROTOCOL_IQIYI` id to handle all the iQIYI traffic, which is basically video streaming traffic.

A video hosting service, called PPS.tv, is still offered by the same company: for the time being we classified both services with the same protocol id.

STUN: improve extraction of Mapped-Address metadata (#2370)
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.

STUN: major code rework (#2116)
Try to have a faster classification, on first packet; use standard extra
dissection data path for sub-classification, metadata extraction and
monitoring.

STUN caches:
* use the proper confidence value
* lookup into the caches only once per flow, after having found a proper
STUN classification

Add identification of Telegram VoIP calls.

Remove special handling of some TCP flows without SYN (#1965)
This piece of code has multiple problems:
* nDPI is able to detect some TCP protocols even with mid-flows (i.e.
without the initial packets of the session); TLS is the most
significative example
* since e6b332aa4a it is perfectly valid
to not pass the TCP Handshake packets to nDPI
* in any case, we shouldn't call `ndpi_detection_giveup()`. That
function is usually called by the application and we end up calling it
twice in some cases.

The simple solution is to completely remove that code: process these
kinds of flows like everyone else.

Note that the application can always avoid to pass to nDPI any TCP flows
without the initial handshake; the flow managemnt is always up to the
application.

Looking at the CI results, some rare flows are now processed significantly
longer. As a follow-up we could look into that.
