Create reverse DNS zone for /24 IPv4 subnet and /64 IPv6 subnet by
default instead of using the netmask from the --ip-address option.
Custom reverse DNS zone can be specified using new --reverse-zone
option, which replaces the old --ip-address netmask way of creating
reverse zones.
The reverse DNS zone name is printed to the user during the install.

The changes include:
* Change license blobs in source files to mention GPLv3+ not GPLv2 only
* Add GPLv3+ license text
* Package COPYING not LICENSE as the license blobs (even the old ones)
mention COPYING specifically, it is also more common, I think
