mail: make The Dragonfly Mail Agent (dma) the default mta.

dma accepts mail from a local Mail User Agent (MUA) and delivers it
locally or to a smarthost for delivery. dma does not accept inbound
mail (i.e., it does not listen on port 25) and is not intended to
provide the same functionality as a full MTA like postfix or sendmail.
It is intended for use cases such as delivering cron(8) mail. which
is the default configuration and usage of sendmail in the default
setup of the base system.

In order to switch the default from sendmail to dma, we teach
mailwrapper to fallback on dma directly if the mailer.conf file cannot
be opened.
We install by default a mailer.conf file which points at dma
We install a mailer.conf file for sendmail in the examples.

mailwrapper: create mailwrapper symlinks for dma(8)

The Dragonfy Mail Agent (dma) can be used with mailwrapper as a
replacement for sendmail(8)

Even if mailwrapper and sendmail are disabled from the build but
dma is not create all the expect symlinks on mailwrapper and make
mailwrapper a symlink to dma, the same way it was done before when
mailwrapper is disabled by sendmail was not.

Discussed with: emaste

mailwrapper: switch mailer.conf to CONFS

This matches what was already being done in dma(8), and should again make
this merge with etcupdate/mergemaster.

pkgbase: resolve mailer.conf conflict WITHOUT_SENDMAIL

When WITHOUT_SENDMAIL is set, we end up with two different mailer.conf that
conflict, and hilarity ensues. There's currently three different places that
we might install mailer.conf:

- ^/etc/Makefile (package=runtime, contingent on MK_MAIL != no)
- ^/libexec/dma/dmagent/Makefile (package=dma, contingent on MK_SENDMAIL !=
no)
- ^/usr.sbin/mailwrapper/Makefile (package=utilities, contingent on
not-installed)

The mailwrapper installation will effectively never happen because the ^/etc
one will first.

This patch simplifies the whole situation; remove the ^/etc/Makefile version
and install it primarily in mailwrapper if MK_MAILWRAPPER != "no". The
scenarios covered in mailwrapper are:

- sendmail(8) is installed, dma(8) may or may not be installed
- neither sendmail(8) nor dma(8) is installed

In the first scenario, sendmail(8) is dominant so we can go ahead and
install the version in ^/etc/mail. In the unlisted scenario, sendmail(8) is
not installed but dma(8) is, we'll let ^/libexec/dma/dmagent do the
installation. In the second listed scenario, we still want to install an
example mailer.conf so just install the base sendmail(8) version.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

The last big commit: let usr.sbin/ use WARNS=6 by default.

- Import the HEAD csup code which is the basis for the cvsmode work.

- Do not bother to do free right before exit() or execve() [O]

actually work and document the fact. [N]
- Avoid using __progname but instead use getprogname()

have sync'ed with their code.

If NO_MAILWRAPPER is set, and sendmail is still enabled, then install
a direct symlink to sendmail.

Add the missing hoststat and purgestat commands. These are normally
symlinks to the sendmail binary but in FreeBSD's case, they are

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

Install mailer.conf as ${BINOWN}, ${BINGRP}, rather than root:wheel. This
lets unprivileged installworld: almost work first try and always work second.

BINOWN isn't quite right for this, but it's not really worth creating
a MAILOWN for this.

Preempt one brucification - I was missing a ${DESTDIR}. I hate merging
two sets of changes from different trees.

As a special case, deal with a missing mailer.conf at install time. I
don't particularly like doing this here, but the alternative (loosing mail)
is worse.
