Rework configure stage. Previously this worked (and in pkgsrc it still
does work) by chance if it did...

Log message:
Re-import dk-milter and dkim-milter. Old versions of these packages
are already in pkgsrc, but since they changed quite a bit I think it's
less invasive to test them first in pkgsrc-wip. The main reason for
this is that dkim-milter requires OpenSSL >=0.9.8 to obey RFC 4871,
but that's not yet available in pkgsrc. I'll import an updated OpenSSL
package to pkgsrc-wip shortly...

Log message:
dk-milter is now in main pkgsrc.

Log message:
Converted USE_GNU_TOOLS to USE_TOOLS.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
The dk-milter package is an open source implementation of the DomainKeys
sender authentication system proposed by Yahoo!, Inc.  It consists of a
library that implements the DomainKeys service, and a milter-based filter
application that can plug in to the sendmail MTA to provide that service
to sufficiently recent sendmail MTAs.

An optional asynchronous resolver library is also provided to work around
limitations of the basic BIND resolver which comes installed on most
systems.
