Log message:
Fixed pkglint warnings. The warnings are mostly quoting issues, for
example MAKE_ENV+=FOO=${BAR} is changed to MAKE_ENV+=FOO=${BAR:Q}. Some
other changes are outlined in

Log message:
Set PKGNAME instead of PKGBASE, as required by
../../mail/courier-maildir/Makefile.common.

Log message:
Update mail/courier-imap to 4.0.6.  Changes from version 4.0.4 include:

	* Use PCRE for pattern-matching.

	* When autopurging messages from a folder based on their
	  timestamp, scan 'new' in addition to 'cur', otherwise mail
	  delivered to the folder directly never gets purged, unless
	  the folder is open.

	* Fix handling of invalid sequence number of 0.

	* NOT operator on content searches.

Log message:
Update mail/courier-imap to 4.0.4.  Changes from version 4.0.1 include:

	* imap: Implemented account groups, administrator group.
	* imapd.c: New OUTBOX_MULTIPLE_SEND option.
	* imap: add LOGGEROPTS and SSLLOGGEROPTS configuration settings
	which are passed to courierlogger to set the application name for
	syslog.

	* tcpd/tcpd.c: Added --accesslocal option.

	* smap: SMAP EXPUNGE >100 msg ranges was broken.

	* PROXY_HOSTNAME: new setting in imap and pop3 config file overrides
	gethostname() when checking if a proxy connection is required.

	* msgbodystructure.c (msgbodystructure): Fix MSGBODYSTRUCTURE response
	for a corrupted content-type of "text".

Log message:
Get rid of USE_PERL5.  The new way to express needing the Perl executable
around at either build-time or at run-time is:

	USE_TOOLS+=	perl		# build-time
	USE_TOOLS+=	perl:run	# run-time

Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.

Log message:
Remove USE_GNU_TOOLS and replace with the correct USE_TOOLS definitions:

	USE_GNU_TOOLS	-> USE_TOOLS
	awk		-> gawk
	m4		-> gm4
	make		-> gmake
	sed		-> gsed
	yacc		-> bison

Log message:
For packages that use GNU configure, don't bother adding "TOOL"
variables into CONFIGURE_ENV if the new tools framework already takes
care of adding them automatically.

Log message:
The courier-imap and sqwebmail packages embed ${SETENV} into scripts, so
pass the real "env" command path to the configure script.  This avoids
the configure script just detecting "env" in the tools directory and
assuming that's the path to the real thing.  This fixes PR pkg/30282.

Log message:
Pass the install-time definition of sysconfdir through to sub-make
processes.  Since courier-imap uses GNU automake, we need to set
AM_MAKEFLAGS to the correct value.  This fixes the installation of
the example config files into ${PREFIX}/share/examples/courier.

Log message:
Sort.
