COLLECTION Functions to deal with hash

The hashing logic was internal to the collection item.
But if someone wants to effectively deal with
the items and compare the property to a string
he should compare hashes first. But it was not possible
without the provided functions. As a result some
of the ELAPI modules had to take advantage of
knowledge of the item structure. This is bad.
So this patch lays foundation for refactoring
of the ELAPI code that was using internals of the item
directly (file_util.c mostly).
Also patch adds a unit test that was required for
testing new functionality and for ticket #83
