fuzz: improve coverage and remove dead code ( #2135 )
...
We are not able to remove custom rules: remove the empty stubs (which
originate from the original OpenDPI code).
`ndpi_guess_protocol_id()` is only called on the first packet of the
flow, so the bitmask `flow->excluded_protocol_bitmask` is always empty,
since we didn't call any dissectors yet.
Move another hash function to the dedicated source file.

Test multiple ndpiReader configurations ( #1931 )
...
Extend internal unit tests to handle multiple configurations.
As some examples, add tests about:
* disabling some protocols
* disabling Ookla aggressiveness
Every configurations data is stored in a dedicated directory under
`tests\cfgs`
