Fix #10671: functionConst FN with begin/end and const_iterator (#3749) 
Check if the iterator is assigned to a const_iterator or
const_revese_iterator, in which case it is possible the function can be
const. Unfortunately, it is not possible to remove the hard coding of
cbegin, cend, crbegin and crend due to the need to handle auto, as in
the following code snippet:

    void cbegin_auto(void)
    {
        for (auto it = m_str.cbegin(); it != m_str.cend(); ++it) {;}
    }

Fix the ability to recognize return types when simplifying attributes. (#3637) 
* Fix the ability to recognize return types when simplifying attributes.

When parsing attributes to remove them, we have to allow for
the case where the return type of the function that follows
the attribute has a namespaced C++ type, like foo::bar .
That means that :: has to be recognized as a valid token.
Fix this in simplifyAttribute, and add tests for this as well.

daca reports new false positives after db4f94fdfe on the form:

	void f() {
	    char *ptr = malloc(10);
	    char *empty_str = "";
	    if (ptr == NULL)
	        ptr = empty_str;
	    if (ptr != empty_str)
	        free(ptr);
	}

Add a check that the value is not impossible to avoid this.
