Log Message:
Updated to version 3.1.2.

Pkgsrc changes:
  - The updates for rule files go into $VARBASE/spamassassin/.
  - This above directory and the directory sa-update-keys for the GPG keys
    are now handled automatically by OWN_DIRS.
  - The growing number of *.pre files are managed in a loop in the Makefile.
    They are no longer contained in the static PLIST.
  - Removed some unnecessary trailing slashes.
  - Patching init.pre in order to disable the SPF plugin broke the spf.t
    test. This is now fixed, although in a rather ugly way :-/.
  - patch-ab no longer needs to use BSD_INSTALL_DATA_DIR because we create
    the directories through INSTALLATION_DIRS.
  - patch-ad and patch-az were removed (changes integrated upstream).
  - patch-bb fixes a small documentation error.
  - Fixed some warnings by pkglint about the SUBST framework in Makefile
    and options.mk.
