In standard DNS format, the first thing on an A, NS or DS definition line is a domain label relative to the zone, which in our case is a TLD. However, the generate_zone_files command prints out fully qualified host and domain names, resulting in a discrepancy when compared to the contents of the DNS subsystem. This CL removes the TLD suffix, which should remove one preprocessing step before file comparison.

Previously, GenerateZoneFilesAction mapreduced its way through all domains and hosts for the specified TLD(s), emitting information for each matching domain and host (subject to constraints like not being deleted and so on). This resulted in host information (aka glue records) for all hosts subordinate to domains in the specified TLD(s). This is incorrect. DNS glue records should only be present for hosts which act as nameservers for their superordinate domains.
The new version of the mapreduce iterates only over domains. When a matching domain is found, a check is made to see whether any subordinate hosts are also nameservers for the domain, in which case host information is generated.
The test was updated to reflect the new reality, and check for a couple additional nuances.

Attending to this old bug will improve our ability to perform zone comparisons between Datastore and the DNS provider. Right now, zone comparison finds some bogus differences, because the TTL we send to the DNS subsystem doesn't match the TTL we use when generating our local dump files.

This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.
