* Revert "Added fix for handling Server Hello before CLient Hello"
This reverts commit eb15b22e7757cb70894fdcde440e62bc40f22df1.
* 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

We can do definitely better, but this change is a big improvements
respect the current broken code

On extra-dissection data-path we only need to look for the hash (the
flow is already classified as Bittorrent).
As a nice side-effect, the confidence is now always with the right
value.

The Train Real Time Data Protocol (TRDP) is a UDP/TCP-based communication protocol designed for IP networks in trains, enabling data exchange between devices such as door controls and air conditioning systems. It is standardized by the IEC under IEC 61375-2-3 and is not related to the Remote Desktop Protocol (RDP).

ISO/IEC 14908-4 defines how to tunnel Control Network Protocol (CNP) over IP networks. It encapsulates protocols like EIA-709, EIA-600, and CNP, making it a versatile solution for building automation and control systems.

If the flow is classified (via DPI) after the first packet, we should
use this information as FPC
|
| |
|
|
|
|
| |
Add printing of fpc_dns statistics and add a general cconfiguration option.
Rework the code to be more generic and ready to handle other logics.

Use DNS information to get a better First Packet Classification.

Let's start with some basic helpers and with FPC based on flow addresses.

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

The original code handled also TCP/TLS, but it was removed in 6fc29b3ae

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.

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.

other_address parsing
Added code to ignore invalid STUN realm
Extended JSON output with STUN information

* Add Label Distribution Protocol support
* Fix typo
* Update unit test results

Microsoft UDP traffic over port ~3478 is voip traffic, using some kind
of proprietary STUN-like protocol: so use the most specific protocol id.
More important, we definitely want `Stun/Skype_TeamsCall` and not
`Stun/Skype_Teams`
