Thomas Niederberger d122b1c722 Fix issue with __declspec and final (#2107)
* Add missing Qt macros

Add two Qt macros that were missing

* Fix issue with __declspec and final

This change is a bit naive but it fixes the issues I was having when combining __declspec(dllexport) and final classes. Without the fix I get errors along the line of "The code 'class x final :' is not handled. You can use -I or --include to add handling of this code. "

Rikard Falkeborn fd3cb24973 leakNoReturnVar: Don't break early (#2095)
There seems to be no reason for stopping checking the scope if a call to
free() is seen (or fclose() or realloc()), so just continue checking.
Also, if there are multiple arguments, check all, perhaps there are more
memory leaks to warn about.

Paul Fultz II ee7fe3aaa1 Fix FP: Unitialized variable when using a pointer
This fixes the FP in cases like this:

```cpp
void f() {
    bool b;
    bool * x = &b;
    if (x != nullptr)
        x = 1;
}
```

It tracks the indirection of the uninit value in valueflow.

Rikard Falkeborn fc1d5b187f leakNoVarFunctionCall: Use AST more (fix #9252) (#2086)
Use the AST a little bit more to improve the check. In order to do so,
rewrite the check to work from the outer function first and then check
the arguments, instead of the other way around.

It also fixes Trac ticket #9252, no warning is now given for

	void* malloc1() {
		return(malloc1(1));
	}

This FP seems to be common in daca results.

It also makes it possible to improve handling of casts, for example
cppcheck now warns about

	void f() {
		strcpy(a, (void*) strdup(p));
	}

But not for

	char* f() {
		char* ret = (char*)strcpy(malloc(10), "abc");
		return ret;
	}

These FP/FN were introduced when the check was switched to use the
simplified token list.
