Log message:
qmail: mark as NOT_FOR_UNPRIVILEGED

Although the package itself builds when pkgsrc is bootstrapped in
unprivileged mode, the pkgsrc +INSTALL/+DEINSTALL scripts fail, causing
bulk build noise:

=> Creating binary package /wrk/mail/qmail/work/.packages/qmail-1.03nb49.tgz
fatal: unable to find user alias
===========================================================================

ERROR: instchown exited 111.

Permissions are likely wrong, and/or the queue may be uninitialized.

===========================================================================
pkg_add: install script returned error status
pkg_add: 1 package addition failed

Log message:
Retire 'djbware-errno-hack' and associated options.mk cleverness.
Instead:

1. Package makefiles including their own options.mk
2. Packages say "SUBST_CLASSES+=djberrno" to get the hack, if needed
3. Packages adjust SUBST_FILES.djberrno, if needed

Should fix bulk build failures due to multiple inclusions of options.mk
and/or incorrect definitions of DJB_ERRNO_HACK.

Approved during the freeze by wiz@.

Log message:
Update to notqmail 1.08 (as qmail-1.03nb49). From the changelog:

## Fix bugs

- Vulnerabilities we've inherited from qmail 1.03, reported by Qualys.
    - CVE-2005-1515: fix signedness wraparound in `substdio_{put,bput}()`.
    - CVE-2005-1514: fix possible signed integer overflow in `commands()`.
    - CVE-2005-1513: fix integer overflow in `stralloc_readyplus()`.
    - Fix several other places where variables could overflow.
- `qmail-pop3d`: instead of running as root if root authenticates (and
  being a vector for a dictionary attack on the root password), exit 1
  to look just like a failed `checkpassword` login.
- `qmail-inject`: do not parse header recipients if `-a` is given.
- Correctly detect multiple IP addresses on the same interface.
- Remove workaround for ancient DNS servers that do not properly
  support CNAME.
- Fix possible integer overflow in `alloc()`.

## Reduce bug likelihood

- Remove `dnscname` and `dnsmxip` programs that were being built but not
  installed.
- Remove `systype` and related platform detection.
- Remove unused variable in `maildir.c`.
- Reduce variable scope in `tcpto.c`.
- Avoid local variables shadowing same-named globals.
- Avoid needing `exit.h` in named-pipe bug check.
- Add a `test` target and some unit tests, using Check.
- Add missing function declarations in `cdbmss.h`, `scan.h`.
- Add missing return types to `main()`.
- Add `hier.h` for inclusion in `instcheck.c`, `instchown.c`, `instpackage.c`.
- Use system headers and types instead of the `HASSHORTSETGROUPS` check.
- Use system headers instead of redeclaring `exit()`, `read()`,
  `write()`, `malloc()`, `free()`, `fork()`, `uint32_t`.
- Use C89 function signatures for code we've touched so far.
- Automated builds:
    - TravisCI: move setting `MAKEFLAGS` out of the script and into
      the matrix.
    - Add FreeBSD builds with CirrusCI.
    - Add a GitHub Actions build.

## Other changes

- Remove DJB's TODO.
- Replace many `pobox.com` URLs.
- Acknowledge Erik Sjölund's `qmail-local.c` bugfix that we've
  inherited from netqmail.
- Avoid generating catted manpages by building with `NROFF=true`.
- Optionally create a `systemd` service file.
- Run an alternate `qmail-remote` by setting `QMAILREMOTE` in
  `qmail-send`'s environment.

## Intent to remove

In the course of developing this release, we found programs that we
intend to remove in the next release. We believe none of these remains
necessary or useful enough to be worth the cost of maintaining. If you
disagree, please let us know!

- Remove `qsmhook`, long since replaced by `preline`.
- Remove inefficient `maildirwatch`.
- Remove obsolete mail client wrappers.
- Remove `qmail-pop3d`, since Maildir is well supported by actively
  maintained POP3 servers.

Log message:
mail/qmail: doesn't need the errno hack anymore

notqmail-1.07 correctly includes <errno.h> instead of declaring errno as
a process-global variable.
