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.

Library configuration: Enable configuring the direction of arguments. (#1717)
This enhances the library configuration so the direction of function
arguments can be specified (in, out, inout).
isVariableChangedByFunctionCall() uses this information now to avoid
guessing.

library.cpp: WarnInfo: Fix crash (#1697)
If no 'alternatives' argument was specified and the `<warn/>` element
did not contain any text Cppcheck crashed because of a null pointer
access.
If there is no 'reason' and no 'alternatives argument and also no text loadFunction() returns with an error.

Paul Fultz II fd3c1fd040 Fix issue 1777: Undefined Behavior: Comparing pointers to different objects
This uses the lifetime analysis to check when comparing pointer that point to different objects:

```cpp
int main(void)
{
    int foo[10];
    int bar[10];
    int diff;

    if(foo > bar)   // Undefined Behavior
    {
       diff = 1;
    }

    return 0;
}
```
