Fix ticket #3317 (same expression false positives)
...
Add a check for function calls that have no side effects. That means
known const methods and a list including strcmp, strlen, etc.
If the function is not known to be side effect-free then no style
warning is given.
Add test cases for the duplicate expressions.

Fix for same expression separated by commas

I've changed the test to use == instead. There was also a missing case
when the expression was followed by a comma instead of being preceded by
one.

Improved same expression check for ticket #3274

Expand the logic for the check for the same expression on both sides of
the || and && operators. Now expressions can be more complex, with the
"alt" variable helping to fudge operator precedence to avoid false
positives.

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.
Ticket: #3165 (Stop misusing the 'information' error severity!)

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.
