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.

autovarInvalidDeallocation: Fix fp with impossible value (#3604) 
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.

Example:

}

With that cppcheck.cfg file cppcheck will always run the "cert" addon. Explicit options such as --addon=cert will not be needed.

Fix handling of namespace scope with several bodystarts (#3438) 
Follow up to 0093452bed.
Give the proper end to getVariableList, since it might not be bodyEnd.

Before that, getVariableList would add the same variables in several
unrelated scopes, and all kind of false positive would follow.

For instance, with the case I added in the unit-tests, I had:
```
../code.cpp:15:18: warning: The struct 'is_A' defines member variable with name 'foo' also defined in its parent struct 'is_A_impl'. [duplInheritedMember]
static const int foo = 8;
                 ^

                 ^

Remove usage of std::vector and getArguments from getTokenArgumentFunction (#3435) 
getTokenArgumentFunction can be called many many times, and the vector
is not needed, but it can become quite costly.
This patch replaces getArguments with a function simply returning the
position of the token, if it is found in the arguments (thus saving the
cost of std::vector).
