Avoid a double call of `ndpi_guess_host_protocol_id()`.
Some code paths work for ipv4/6 both
Remove some never used code.

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.

Content-matched sub-protocols (DASH, IPP, MPEGDASH...) shouldn't
ovewrite the previous master protocol (if any; usually HTTP).
Furthermore. the HTTP dissector shouldn't update the classification
(in the extra-dissection code path) if a content-matched sub-protocols
has already been found.
This commit should address the first part of the changes described in #1687.

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.

Remove some unused protocol bitmasks.
Update script to download Whatsapp IP list.
