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.
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.

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.

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.

* Add detection of Gaijin Entertainment games
* Short NDPI_PROTOCOL_GAIJINENTERTAINMENT to NDPI_PROTOCOL_GAIJIN
* Add default UDP port for Gaijin Entertainment games
* Remove NDPI_PROTOCOL_CROSSOUT protocol id
Avoid collisions between user-ids and internal-ids protocols in the
`example/protos.txt` file.
Add a new value for the classification confidence:
`NDPI_CONFIDENCE_CUSTOM_RULE`
With `./example/ndpiReader -p example/protos.txt -H` we now see also the
custom protocols and their internal/external ids:
```
nDPI supported protocols:
Id Userd-id Protocol Layer_4 Nw_Proto Breed Category
0 0 Unknown TCP X Unrated Unspecified
...
387 387 Mumble UDP X Fun VoIP
388 388 iSCSI TCP Acceptable Unspecified

399 2049 CustomProtocolF TCP Acceptable Unspecified
400 2050 CustomProtocolG TCP Acceptable Unspecified
401 65535 CustomProtocolH TCP Acceptable Unspecified
```
We likely need to take a better look in general at the iteration between
internal and external protocols ids...
