[Libguestfs] [PATCH v3] perl: Add explicit close() method (RHBZ#602592).

This contains some minor improvements on the previous iteration. The only significant change is that we no longer construct the whole hash from the XS code, since that's quite complex and error-prone. Instead the C _create function returns a plain IV and we construct the hashref on the Perl side.
