Add new port dns/dnstable

[truckman]

Summary

dnstable implements an encoding format for passive DNS data. It
consists of a C library, libdnstable, and several command line
utilities for creating, querying, and merging dnstable data files.

It stores key-value records in Sorted String Table (SSTable) files
and provides high-level interfaces for querying or iterating over
the stored records. dnstable encodes individual records using a
format tailored for efficiently storing passive DNS data and can
quickly perform both "forward" and "inverse" searches.

Test Plan

Fetch distfiles from both MASTER_SITES.

Build on FreeBSD 8.4, 9.3, 10.1, and 11.0-CURRENT, both amd63 and i386.

We usually do this a bit more the make way, something like:

.for i in 1 3 5 7
	${INSTALL_MAN} ${WRKSRC}/man/*.${i} ${STAGEDIR}/${PREFIX}/man/man${i}/
.endfor

Hmn ... never used that make feature before.

[truckman]

Use a make .for loop to install man pages instead of shell for loop.

Looks all good. As a side note, as you're upstream, you could release the sources tarballs as .tar.xz to save up on download bandwidth for your users :-)

Yeah, I'll suggest that. At least they are pretty small to begin with. Way faster to download than openoffice.
