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

PKEuS 8f79dc3ff8 Cleaned up includes and forward declarations in checkers: 
- Removed definitely unnecessary forward declarations (e.g. "class Token"; token.h is already included by check.h, so a definition is unnecessary)
 - Removed unused includes
