Log message:
Document config-fast-pkgsrc in README.pkgsrc, too.

Log message:
Update from netqmail 1.06 (2007) to notqmail 1.07 (just released). From
the changelog:

- code: remove incorrect usage of vfork()
- code: detect and prefer utmpx where available
- code: removed idedit, install-big. var-qmail packages are no more
- portability problem: explicitly initialize strerr_sys and
  define BIND_8_COMPAT to work around Mac OS X
- code: add instchown to set ownership and mode on installed files
- code: add instpackage to install without root access
- doc: rename INSTALL, SENDMAIL to INSTALL.md, SENDMAIL.md to
  support building on case-insensitive filesystems
- code: lookup uid/gid at runtime
- code: use DESTDIR environment variable as root directory in install

pkgsrc changes:

- If hostname isn't FQDN, config-fast-pkgsrc wouldn't produce a working
  config, so don't run it; tell user what to do instead
- Stage QMAIL_QUEUE_DIR into DESTDIR/tmp, to be more obvious that it's
  not being packaged up (and is not how a queue gets created at
  pkg_add time)
- Drop custom destdir, qbiffutmpx, and Darwin patches
- Rebase TLS-onlyremote, QMAILREMOTE, and SRS patches
- Require latest ucspi-ssl and ucspi-tcp6 for IPv4 fixes
- Move MESSAGE.tls to README.tls, and remove other MESSAGE*
- Set PKG_HOME even for non-default values of QMAIL_ALIAS_USER
- Check whether alias/.qmail-foo exist before trying to remove

Bump PKGREVISION.

Log message:
qmail's queue is expected to work just fine on a case-insensitive FS.
Remove the INSTALL check and warning.

Log message:
BIGDNS_PATCH has been reliably reachable; remove from MASTER_SITE_LOCAL.
OUTGOINGIP_PATCH needs to come from a qmail.org mirror, as the original
domain has lapsed; get it from mine.

Log message:
qmail.org domain lapsed. netqmail.org has not, as yet.

Log message:
Use CPPFLAGS, not CFLAGS, for consistency with ucspi-tcp6 and djbdns.

Log message:
Keep it simple: libtai does not futz with PKG_SYSCONFSUBDIR.

Log message:
Update to tlsonlyremote 20190408, cut from upstream TLS patch with the
same date. Fixes build with OpenSSL 1.1 and includes pkgsrc's #ifdef
guards for non-TLS builds. Bump PKGREVISION.

Log message:
Apply the "tai-leapsecs" patch iff the 'tai-system-clock' option is set
(off by default). Bump PKGREVISION.

Log message:
Add Toby Betts' "tai-leapsecs" patch to handle leap seconds correctly
when the system clock is set to TAI (and a libtai dependency to get
leapsecs.dat). While here, catch up to his latest maildiruniq patch.

Let an installed ucspi-tcp6 satisfy the ucspi-tcp dependency for
non-'inet6' builds.

Bump PKGREVISION.
