Paul Fultz II 7ef119cbfc Fix FPs in lifetime checker
This fixes several FPs in the lifetime checker. It also fixes issue [8846](https://trac.cppcheck.net/ticket/8846):

```cpp
int * f(int a[])
{
        return a;
}
```

several improvements to help with users that have a development workstation without a native version of astyle with the expected version

patch 2 is the most important and less intrusive change towards that objective but the whole series completes the feature, including parts of patch 4 that will allow for example users with spaces on their username to point to a binary no their home directories.

I decided against splitting the changes on 2 patches for simplicity and because I was expecting the whole series might be squashed for merging anyway
