Moving from 4.8 to 4.10 (and so, from 4.9 to 4.11 for development builds)
made some paths one character longer; that triggers an error with tar
when running `verify_dist_tarball.sh` script:
```
tar: libndpi-4.11.0/fuzz/corpus/fuzz_filecfg_config/flow_risk.anonymous_subscriber.list.protonvpn.load.txt: file name is too long (max 99); not dumped
```
As a quick fix, reduce the length of that file name.
Some changes in the parameters names.
Add a fuzzer to fuzz the configuration file format.
Add the infrastructure to configuratin callbacks.
Add an helper to map LRU cache indexes to names.
