Introduce AbstractPos
This makes the position object used in exceptions abstract, with a method getSource() to get the source code of the file in which the error originated. This is needed for lazy trees because source files don't necessarily exist in the filesystem, and we don't want to make libutil depend on the InputAccessor type in libfetcher.
