Create dedicated path resolver for the flat classpath representation

This commit adds dedicated FlatClassPathResolver loading classpath
entries as FlatClassPath.

Most of the common logic from PathResolver for the old classpath has
been moved to the base, separate class which isn't dependent on
a particular classpath representation. Thanks to that it was possible
to reuse it when creating an adequate path resolver for the flat
classpath representation.

This change doesn't modify the way the compiler works. It also
doesn't change nothing from the perspective of someone who already
uses PathResolver in some project or even extends it - at least as
long as he/she doesn't need to use flat classpath.

There are also added JUnit tests inter alia comparing entries created
using the old and the new classpath representations (whether the flat
one created using the new path resolver returns the same entries as
the recursive one).
