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 )

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.

Library configuration: function argument direction fixes and enhancements (#1722) 
* std.cfg: Add further argument directions (in, out, inout).

* testlibrary.cpp: Add test for function argument direction configuration.

* std.cfg: runastyle and add some more direction configurations.

* library.h: Add documentation for function argument direction enum.

* Do not use "direction" library information for pointer arguments.

Also fix further unmatched uninitvar messages in std configuration
tests.

* std.cfg: Add more argument direction configurations.

* test/cfg/std.c: Add test for argument direction configuration.

* astutils.cpp: Only ignore pointer arguments for out/inout arguments.

* library.h: Use suggested documentation for argument direction enum.
