Log Message:
Change the default directory for the various pid files to be
${COURIER_STATEDIR}/tmp, which defaults to /var/courier/tmp.  This
allows some of the servers which drop root privileges too soon to still
write the pid file into a courier-owned directory instead of the
root-owned /var/run.

In mail/courier-mta, de-list ${COURIER_STATEDIR}/webmlm from the list
of owned directories.  In fact, webmlmd expects that path to be a
socket file, and breaks horribly if the "webmlm" directory is present
instead.

Bump PKGREVISIONs for the following packages:

	mail/courier-imap	--> 2
	mail/courier-mta	--> 9
	mail/sqwebmail		--> 4
	meta-pkgs/courier	--> 5
