Merge r17574, r17575, r17584, r17585, r17628, r17639 from trunk to delete deprecated cgi-bin configuration interfaces

The CGI interfaces have not been maintained; the interfaces available through
the Admin -> Server Administration menu in the staff client are the recommended
method for setting up new libraries in the organizational hierarchy,
permissions, copy statuses, and circulation rules.

Note that an adjustment to eg.conf is recommended to point to the
offline.pl script, which is the only remaining CGI script in use; this
should avoid conflicting Apache definitions for the /cgi-bin/ alias.

Most modern systems will install Class::DBI::Frozen::301 to avoid
conflicts with incompatible Class::DBI packages. We need to teach
offline.pl how to use Class::DBI::Frozen::301 if it is available.

Note that we're using "use parent" instead of "use base" per the
recommendation of "perldoc base"; accordingly, we're adding the
system prerequisite for the parent pragma.
