errno must be accessed by a macro from errno.h.

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.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

qmail.org is gone, link to cr.yp.to/qmail.html instead

qmail.org has disappeared and there's no evidence it is coming back.

- Switch to options helpers
- Cosmetic fixes

Farewell qmail. You were good but the lack of an upstream maintainer or
ecosystem maintainers makes this not a viable mail system today. Personally
I am moving to postfix and have so far found it incredibly easy to setup and
already prefer it over qmail.

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

This is a small utility for checking and repairing the qmail queue
structure.  It will fix uid/gid settings and permissions.  It will
rename the message files to match their inodes.  It will even create
directories and files that don't exist that should be there (you can
even create a queue from scratch).  It will also print warnings for
any files it finds that should not exist.
