Fix 11579: false negative: knownConditionTrueFalse with non-bool as bool parameter ( #5349 )
...
This adds a new checker to check for pointer to bool conversions that
are always known. I removed the previous knownConditionTrueFalse checks
since this was too noisy.

removed unnecessary `Settings` parameter from `Check::runChecks()` and made `Tokenizer` a reference ( #5308 )
...
There was no need for the `Tokenizer` parameter to be a pointer as it
could never be `nullptr` and was also dereferenced without checking
first.
As a reference to the `Settings` was already available via the
`Tokenizer` there was no need to pass it separately. In the production
code there will only be one instance of it but in the tests we could
have accidentally passed a different one.

* cppcheck.cpp: Check for JSON error when parsing addon .json files
This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().
