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.

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.
