rikardfalkeborn 869e4ba6ab Add check for return value of boolean function (#1451)
* Add check for return value of boolean function

The rule for converting an integer to a boolean is that 0 is mapped to
false and everything else is mapped to true. There is nothing wrong with
the following code (according to the standards):

    bool f()
    {
        return -1;
    }

and neither gcc nor clang will warn about it. However, it's a bit
confusing. This commit adds a check that warns when a value other than 0
or 1 is returned from a boolean function (similar to the existing check
that functions with boolean arguments are only passed 0 or 1). Since the
code is perfectly legal, set the severity to "Style".

* Use early continue and remove some braces

* Add testcase with multiple returns

* Avoid null pointer dereference in case of return without operand

* Skip lambdas

Add TODO-test cases that shows FPs when the return type of lambdas are
specified explicitly (this is a problem with findLambdaEndToken).

* Enable testcases

Markus Elfring 02c2018f25 Addition of a null pointer check in ProjectFileDialog::removeSuppression() (#1457)
The function “QListWidget::takeItem” is documented in the way
that a null pointer can be returned. This result was not checked
by the function “ProjectFileDialog::removeSuppression” so far.
Thus add a corresponding check so that an inappropriate pointer access
should not happen any more here.

Daniel Marjamäki ab08801dc4 Remove header tests from testconstructors, because they were invalid (using preprocessor directive)
The checker does not care if it's a header or source file. So I guess these tests were added to test
some parsing problem. Nowadays, #line is removed by simplecpp::preprocess, but there is no proper
testing for it in simplecpp.. I will add some testing for #line asap.

IOBYTE 0763fdbfad Copy template default argument values from forward declaration to declaration. (#1447)
It is possible to define default template parameter values in forward
declarations and not define any in the actual declaration.  Cppcheck
ignores forward declarations and only uses the default values in the
actual declaration so default values in forward declarations are copied
to the actual declaration when necessary.
