DNS: Make AFS go to the DNS for AFSDB records for unknown cells
Add DNS query support for AFS so that it can get the IP addresses of Volume
Location servers from the DNS using an AFSDB record.
This requires userspace support. /etc/request-key.conf must be configured to
invoke a helper for dns_resolver type keys with a subtype of "afsdb:" in the
description.

If you say Y here, you will get an experimental Andrew File System
driver. It currently only supports unsecured read-only AFS access.
