Refactor the same expression check
...
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.
The pointer to symbol database and ref to list of const functions are
temporarily stored in the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.
Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.

Move "information" errors to "style" errors.
...
"information" severity is documented in lib/errorlogger.h as:
Checking information.
Information message about the checking (process) itself. These
messages inform about header files not found etc issues that are
not errors in the code but something user needs to know.
It IS NOT for errors in the code. All the current "information"-
severity errors fit nicely into description of the "style"-
severity.
We definitely need to separate processing information and actual
errors in the code. It is highly confusing for users to mix these
two different things. Hence all current "information" code error
messages are moved to "style" category.

Use "enabled" list for the style checking.
...
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.
Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.
