                        determine which DS records should be published
                        in the parent zone, or which DLV records should be
                        published in a DLV zone, and queries the DNS to
                        ensure that it exists. (Note: This tool depends
                        on python; it will not be built or installed on
                        systems that do not have a python interpreter.)

- moved checkds.py from contrib to bin/python/dnssec-checkds.py
- moved tests from contrib to bin/tests/system/checkds
- set up configure to find the python path

Currently hard-coded to check for 'isc.org'; later this will
be a command line argument.
