Remove some old protocols (#1832)

These protocols:
* have been addeded in the OpenDPI era
* have never been updated since then
* we don't have any pcap examples [*]

If (and it is a big if...) some of these protocols are still somehow
used and if someone is still interested in them, we can probably
re-add them starting from scratch (because the current detection
rules are probably outdated)

Protocols removed: DIRECT_DOWNLOAD_LINK, APPLEJUICE, DIRECTCONNECT,
OPENFT, FASTTRACK, SHOUTCAST, THUNDER, AYIYA, STEALTHNET, FIESTA,
FLORENSIA, AIMINI, SOPCAST

PPSTREAM dissector works (...) only on UDP.

[*]: with do have an AIMINI test pcap but it was some trivial http
traffic detected only by hostname matching, on domains no more
available...
