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) {;}
    }

std.cfg: Add configuration and tests for std::bind() (#2207)
TODO:
Somehow Cppcheck fails to print an ignoredReturnValue message when the
return value is not used (see ticket 
https://trac.cppcheck.net/ticket/9369 )
2019-09-24 12:16:13 +02:00
Paul Fultz II ba037837c9 Track lifetime across multiple returns
This will now warn when doing something like this:

```cpp
template <class T, class K, class V>
const V& get_default(const T& t, const K& k, const V& v) {
    auto it = t.find(k);
    if (it == t.end()) return v;
    return it->second;
}
const int& bar(const std::unordered_map<int, int>& m, int k) {
    auto x = 0;
    return get_default(m, k, x);
}
```

The lifetime warning is considered inconclusive in this case.

I also updated valueflow to no tinject inconclusive values unless `--inconclusive` flag is passed. This creates some false negatives because library functions are not configured to not modify their input parameters, and there are some checks that do not check if the value is inconclusive or not.
