This patch adds convenience functions to work with absolute paths.
The function is_absolute_path() should help the efforts to integrate
the MinGW fork.
Note that make_absolute_path() returns a pointer to a static buffer.

I am in the middle of so many things, otherwise I would have
tried to find all places that can use these functions. But
maybe a helpful soul out there wants to do that?
