Log message:
Update net/couriertcpd to 0.56.0.  Changes from version 0.53.2 include:

+ Remove BDB_LIB workaround which should already be handled by the wrapper
  scripts and db1.builtin.mk.
+ Remove unnecessary patch-aa and patch-ab.

* Setting protocol to SSL3 will now disable SSL2.
* Send a dummy EHLO before STARTTLS (gmail wants it).
* Allow setting the max # of connections on a per-IP address basis.

Log message:
Fix botched migration of PKG_OPTIONS from courier-mta/Makefile.common
into the Makefiles of the packages that include it:

(1) PKGNAME and PKG_SUPPORTED_OPTIONS clearly no longer need to be
    defined since the only code that used it in Makefile.common was
    removed.

(2) Package Makefiles need to properly define PKG_OPTIONS_VAR and
    PKG_SUPPORTED_OPTIONS prior to including bsd.options.mk.  Set
    them to the appropriate values to match the orginal names from
    before the botched migration.

Log message:
This package has no options, but uses a Makefile.common which includes
bsd.options.mk. Therefore, an empty PKG_SUPPORTED_OPTIONS is needed.

Log message:
Made an error message friendlier (patch-ab).

Fixed pkglint warnings.

Log message:
Fix build on Linux.  Replace link to -ldb with BDB_LIBS.  Avoid automake
refresh.  This addresses PR#33802

Log message:
Install couriertcpd into sbin, which is the location expected by stock
courier-mta and courier-imap.  Bump the PKGREVISION on all three
packages.

Log message:
Add a buildlink dependency on openssl to couriertcpd, which needs the
SSL libraries to build couriertls, which encapsulates the logic for
handling SSL connections for Courier services.  Drop the dependency
on openssl from both courier-imap and courier-mta, which only need
the "openssl" tool instead.  Bump the PKGREVISIONs for all three
packages due to the changed dependencies.  Problem noted by Ondrej
Tuma in private email.

Log message:
Import couriertcpd and couriertls from courier-mta-0.53.2 as
net/couriertcpd.

This package contains couriertcpd(1), used to daemonize the Courier
services, and couriertls(1) used to provide TLS support for the Courier
services that support them.
