MFC r326276:

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

MFC r314659,r314676:

r314659:

usr.sbin: normalize paths using SRCTOP-relative paths or :H when possible

This simplifies make logic/output

r314676:

Fix build after r314656

Some of the changes I introduced to use .ALLSRC were correct in spirit,
but incorrect in reality -- in particular, ../Makefile.inc hadn't been
pulled in via bsd.init.mk (via bsd.lib.mk, bsd.prog.mk), so the value
of .ALLSRC (evaluated immediately) was empty. .include bsd.init.mk
explicitly so we can be certain that the values used as dependencies in
the targets are defined when the target recipe has been evaluated.

Reminder: thou shalt separate out separate functional changes before
committing them.

Convert absolute links to relative links.
Style.Makefile(9) has been ignored to produce minimal diffs.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Create the /bin/rmail symlink (which mailers such as postfix
and Exim can use).

This is something I thought I committed MONTHS ago, but it appears
that I fatfingered it and made a local commit.

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

Markup fixes.

Update NetBSD and OpenBSD SCM tags to match the reality. Note that
NetBSD revisions 1.8 and 1.9 are not actually applied to our code base
because we have solved the problem differently, therefore, these changes
can be safely skipped.

Merge all applicable NetBSD and OpenBSD improvements over this manpage
till NetBSD mailwrapper.8,v 1.11 and OpenBSD mailwrapper.8,v 1.8:

- Separate exit status out from diagnostics section.
- Fix typos.

Cleanups for mailwrapper(8):
- K&R -> ANSI prototype [O]
- Do not bother to do free right before exit() or execve() [O]
- Remove some dead code in addarg()
- Make additional parameters specified in mailer.conf(5)
actually work and document the fact. [N]
- Avoid using __progname but instead use getprogname()
and setprogname() to provide more sensible messages. [O, N]
- Update $OpenBSD$ and $NetBSD$ to reflect the fact that we
have sync'ed with their code.

Don't free memory that was never allocated. This fixes a core dump in

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.

Remove whitespace at EOL.

You can't free a string and then use it as the error message to
errx. Instead use warn to print the string, then cleanup and exit
normally.

This fixes a core dump if the executable to be run doesn't exist.

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

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

remove trailing periods from SEE ALSO.

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.

Do not add progname in err() strings, it will be printed twice

Submitted by: Brian Handy <handy@physics.montana.edu>

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Merge from OpenBSD:
o Realloc memory leak fixed which won't matter but would trigger purify
o Default to sendmail when no mailer.conf exists.

Fixed bugs in OpenBSD version:
o Add NULL termination in the right place.

Also put back the err. free shouldn't touch errno.

Pointed out by: theo de raadt (except the NULL bug :-)

Fix mysterious sendmail coredump on systems where malloc.conf pointed to
a string containign 'J'.

o Properly terminate argv list with a NULL entry.
o Use warn() to report the exec failure because free could change errno and
err would report the wrong reason.
o Don't terminate string to err with ':' since this results in two colons.

/etc -> /etc/mail

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.

Move mailer.conf to /etc/mail at obrien's request.
