Log message:
Packages have no business modifying PKG_DEFAULT_OPTIONS -- it's a
user settable variable.  Set PKG_SUGGESTED_OPTIONS instead.  Also,
make use of PKG_OPTIONS_LEGACY_VARS.

Log message:
- Sort PLIST.
- Share MASTER_SITES and HOMEPAGE with poppassd package with introducing
  QPOPPER_MASTER_SITES and QPOPPER_HOMEPAGE in Makefile.common.

No functional change.

Log message:
RCD_SCRIPTS_EXAMPLEDIR is no longer customizable.
And always is defined as share/examples/rc.d
which was the default before.

This rc.d scripts are not automatically added to PLISTs now also.
So add to each corresponding PLIST as required.

This was discussed on tech-pkg in late January and late April.

Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere
and remove the RCD_SCRIPTS_EXAMPLEDIR itself.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add RMD160 digests.

Log message:
Update qpopper package to 4.0.5nb7.

- Explicitly add "--disable-ipv6" when inet6 is disabled.
- Fix compile error when inet6 is disabled.  This should fix PR pkg/28805.

Log message:
Remove inet6 from PKG_DEFAULT_OPTIONS. When USE_INET6 is defined it will set
inet6.
Move to calling all such flags 'inet6'.

Log message:
The default location of the pkgsrc-installed rc.d scripts is now
under share/examples/rc.d. The variable name already was named
RCD_SCRIPTS_EXAMPLEDIR.

This is from ideas from Greg Woods and others.

Also bumped PKGREVISION for all packages using RCD_SCRIPTS mechanism
(as requested by wiz).

Log message:
qpopper supports reloading config files with SIGHUP, so enable the
"reload" command.

Log message:
move ssl and ipv6 options to new options.mk framework (no change to
existing defaults) and while here, add QPOPPER_SPOOL_DIR to define spool
directory (no change to existing default).
