Japanese Yahoo domains are missed. Add yahoo.co.jp, yimg.jp, and the

IRC has its best times well behind, but there are still some servers
using it.
We should try to simplify the detection logic, still based on OpenDPI
logic.
Let's start with some easy changes:
* try to detect TLS connection via standard hostname/SNI matching,
removing an old heuristic (we have never had any trace matching it);
* add some basic server names;
* once we detect that the flow is IRC, we don't have to perform
anything else;
* remove HTTP stuff; real HTTP flows never trigger that data path
* use `ndpi_memmem()` when possible

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.

* Added
size_t ndpi_compress_str(const char * in, size_t len, char * out, size_t bufsize);
size_t ndpi_decompress_str(const char * in, size_t len, char * out, size_t bufsize);
used to compress short strings such as domain names. This code is based on
https://github.com/Ed-von-Schleck/shoco
* Major code rewrite for ndpi_hash and ndpi_domain_classify
* Improvements to make sure custom categories are loaded and enabled
* Fixed string encoding
* Extended SalesForce/Cloudflare domains list

The basic idea is to have the following logic:
* pattern "DOMAIN" matches the domain itself (i.e exact match) *and* any
subdomains (i.e. "ANYTHING.DOMAIN")
* pattern "DOMAIN." matches *also* any strings for which is a prefix
[please, note that this kind of match is handy but it is quite
dangerous...]
* pattern "-DOMAIN" matches *also* any strings for which is a postfix
Examples:
* pattern "wikipedia.it":
* "wikipiedia.it" -> OK
* "foo.wikipedia.it -> OK
* "foowikipedia.it -> NO MATCH
* "wikipedia.it.com -> NO MATCH
* pattern "wikipedia.":
* "wikipedia.it" -> OK
* "foo.wikipedia.it -> OK
* "foowikipedia.it -> NO MATCH
* "wikipedia.it.com -> OK
* pattern "-wikipedia.it":
* "wikipedia.it" -> NO MATCH
* "foo.wikipedia.it -> NO MATCH
* "0001-wikipedia.it -> OK
* "foo.0001-wikipedia.it -> OK
Bottom line:
* exact match
* prefix with "." (always, implicit)
* prefix with "-" (only if esplicitly set)
* postfix with "." (only if esplicitly set)
That means that the patterns cannot start with '.' anymore.
