Add detection over TCP and fix detection over IPv6.
Rename some variables since Stun dissector is no more "udp-centric".
Stun dissector should always classified the flow as `STUN` or
`STUN/Something`.
Don't touch `flow->guessed_host_protocol_id` field, which should be
always be related to "ip-classification" only.

The host automa is used for two tasks:
* protocol sub-classification (obviously);
* DGA evaluation: the idea is that if a domain is present in this
automa, it can't be a DGA, regardless of its format/name.
In most dissectors both checks are executed, i.e. the code is something
like:
```
ndpi_match_host_subprotocol(..., flow->host_server_name, ...);
ndpi_check_dga_name(..., flow->host_server_name,...);
```
In that common case, we can perform only one automa lookup: if we check the
sub-classification before the DGA, we can avoid the second lookup in
the DGA function itself.

Add (basic) internal stats to the main data structures used by the
library; they might be usefull to check how effective these structures
are.
Add an option to `ndpiReader` to dump them; enabled by default in the
unit tests.
This new option enables/disables dumping of "num dissectors calls"
values, too (see b4cb14ec).

Since e6b332aa, we have proper support for detecting client/server
direction. So Tinc dissector is now able to properly initialize the
cache entry only when needed and not anymore at the SYN time; initializing
that entry for **every** SYN packets was a complete waste of resources.
Since 4896dabb, the various `struct ndpi_call_function_struct`
structures are not more separate objects and therefore comparing them
using only their pointers is bogus: this bug was triggered by this
change because `ndpi_str->callback_buffer_size_tcp_no_payload` is now 0.

Tcp retransmissions should be ignored.
Remove some unused protocol bitmasks.
Update script to download Whatsapp IP list.

Skype detection over TCP has been completely disable since 659f75138 (3
years ago!).
Since that logic was too weak anyway, remove it.
