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.

Approved by:		portmgr (tcberner)

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.

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

mail/qmail-dk: Fix build with lld

/usr/bin/ld: error: duplicate symbol: scan_ulong
>>> defined at scan_ulong.c
>>>            scan_ulong.o:(scan_ulong) in archive fs.a
>>> defined at scan_ulong.c
>>>            scan_ulong.o:(.text+0x0)

http://beefy12.nyi.freebsd.org/data/head-amd64-default/p474767_s336359/logs/qmail-dk-0.54_1.log

scan_ulong.o is added to fs.a and appears twice in the link command
line (via fs.a and listed explicitly) which results in a duplicate
symbol error with lld.  Removing scan_ulong.o from the link command
line would result in an undefined reference error when linking
auto-int with ld.bfd, so remove it from fs.a instead.

Attempt to build on aarch64 again as the error message is the same.

PR:		221812
Reported by:	emaste, pkg-fallout

Mark these ports as broken on aarch64, and, where appropriate, armvX.

While here, pet portlint and modernize.

mail/qmail-dk: document SSL requirement and support its configuration

While here, remove a bunch of ineffective sed commands against the main
makefile.

Remove ${PORTSDIR}/ from dependencies, categories m, n, o, and p.

- Fix installation from non-root

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:*.

Pass maintainership of qmail ports and bsd.mail.mk to bdrewery@. It was funny,
but I'm not using qmail for a long time.

Mark all my ports as MAKE_JOBS_SAFE and MAKE_JOBS_UNSAFE

RESTRICTED is intended here instead of NO_PACKAGE
