Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

dns/dnshistory: fix build on recent current

Remove libpcre.so.3 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

USE_BDB cleanup.

- USE_BDB=4x+ -> USES=bdb.
- USE_BDB=yes -> USES=bdb.
- USE_BDB=xx  -> USES=bdb:xx.

Other modernisations when I see them.

Remove ${PORTSDIR}/ from dependencies, categories d, e, f, and g.

The website for dnshistory is alive again. Restore it to MASTER_SITES. In
the period during which the website did not exist, the codebase also appeared
on launchpad.net, so add that as a backup MASTER_SITE.

Pass maintainership to Chris Hutchinson.

Upstream has disappeared, so I'm hosting this file on MASTER_SITE_LOCAL.
It is the DNS caching system designed to work with www/awffull so it is
worth keeping this port alive.

Also, switch to USE_BDB=yes instead of 42+.

Drop maintainership of this port. It's stable with no known failures, and
is unlikely to ever see another release.

Berkeley DB cleanup, remove versions 4.0 ... 4.7.
- Mk/bsd.database.mk rewrite, new default to db5.
- db6 is eligible by default only if installed on the system.
- Bump PORTREVISION of all ports that directly depend on BerkeleyDB or
  where USE_BDB is found in the port's directory
- Patch a few ports such that they will pick up or work with newer
  versions.
- Add UPDATING entry
- Drive-by format fix for pks
- Drop BerkeleyDB option from mail/popular for now, requires more work.
- Exp-run logs linked from the PR below.
- Ports that do not build (IGNORE, BROKEN, etc.) have pro-forma changes
  for new Berkeley DB, but are untested.

NOTE: please read UPDATING and the Wiki page before proceeding!

Fix typo.

This port requires libdb.so, so change USE_BDB to 4.2+.

Add dns/dnshistory. It caches DNS lookups into a BDB database. It's designed
to be used with awffull.

Provide a means for storing a history of DNS/Name changes for the IP Addresses
extracted from web log files. The major target being that multiple analyses of
older log files do not require re-lookups of IP Address to FQDNs, and
additionally maintain the accuracy of the lookup as it was then and not as it
is now.
