    return x;
}
int * g(int x) {
    return f(&x);
}

Rikard Falkeborn a69a570505 Fix FP leakVarNotUsed with freopen() and stdin (#2034) 
One usecase for freopen() is to redirect input and output streams to
files. For that, the return value is not needed.

Scott Furry 88e2e82039 Correct Signal/Slot signatures (#2035) 
Previous commit had updated declarations in Code Editor Style Dialog to use
const QColor& and const QFont::Weight& variables. This change was not totally
complete as const usage was not propagated to Signal/Slot connect statements.

This commit corrects that oversight.

.travis.yml: Check more Python scripts with pylint (#2019) 
Use renamed pylintrc file that is only meant for Travis checks.

Check all Python scripts in 'addons', 'htmlreport' and 'tools'

Errors for `_socketobject` class are disabled, see
https://stackoverflow.com/questions/10300082/how-to-prevent-python-pylint-complaining-about-socket-class-sendall-method

Install imported modules `unittest2` and `pexpect` via pip.

Add "./addons" to search-path for modules because
"tools/compare-ast-clang-and-cppcheck.py" imports cppcheckdata.py from
addons. Pylint does not seem to evaluate
`sys.path.insert(0, '../addons')` in the script. So an `init-hook` is
necessary in pylintrc_travis.
