Rikard Falkeborn 5b5d943976 Remove testfiles.pri (#2106) 
qmake is not used to build tests. The only user of testfiles.pri was
removed in 392cda8bce in december 2015.

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.

Paul Fultz II c0c6f92221 Fix issue 8431 and 8776: Size of constant string 
Fixes these cases:

```cpp
void f(void) {
        const std::string msg="xyz";
        if(!msg.empty()){} // Always true
}
```

And out of bounds access:

```cpp
#include <string>
char fstr1(){const std::string s = "<a><b>"; return s[42]; }
wchar_t fwstr1(){const std::wstring s = L"<a><b>"; return s[42]; }
```

Rikard Falkeborn cd36f8ed0a Fix #9253: leakNoVarFunctionCall: do not warn if freopen opens standard stream (#2076)

reopen a standard stream. There is no longer a warning for

	void f() {
		assert(freopen("/dev/null", "r", stdin));
