Extend tests coverage (#1476)

Now there is at least one flow under `tests/pcap` for 249 protocols out
of the 284 ones supported by nDPI.

The 35 protocols without any tests are:

* P2P/sharing protocols: DIRECT_DOWNLOAD_LINK, OPENFT, FASTTRACK,
EDONKEY, SOPCAST, THUNDER, APPLEJUICE, DIRECTCONNECT, STEALTHNET

* games: CSGO, HALFLIFE2, ARMAGETRON, CROSSFIRE, DOFUS, FIESTA,
FLORENSIA, GUILDWARS, MAPLESTORY, WORLD_OF_KUNG_FU

* voip/streaming: VHUA, ICECAST, SHOUTCAST, TVUPLAYER, TRUPHONE

* other: AYIYA, SOAP, TARGUS_GETDATA, RPC, ZMQ, REDIS, VMWARE, NOE,
LOTUS_NOTES, EGP, SAP

Most of these protocols (expecially the P2P and games ones) have been
inherited by OpenDPI and have not been updated since then: even if they
are still used, the detection rules might be outdated.

However code coverage (of `lib/protocols`) only increases from 65.6% to
68.9%.

Improve Citrix, Corba, Fix, Aimini, Megaco, PPStream, SNMP and Some/IP
dissection.
Treat IPP as a HTTP sub protocol.
Fix Cassandra false positives.

Remove `NDPI_PROTOCOL_QQLIVE` and `NDPI_PROTOCOL_REMOTE_SCAN`:
these protocol ids are defined but they are never used.

Remove Collectd support: its code has never been called. If someone is
really interested in this protocol, we can re-add it later, updating the
dissector.

Add decoding of PPI (Per-Packet Information) data link type.
