- Update to version 4.40

- Support for WITH_SPF and WITH_SRS via libspf2/libsrs2, needs exiscan

- Note for 5.x users: the default location of the start/stop file has changed.
  Build WITH_RCORDER=yes when you depend on the old behaviour

- WITH_OPENLDAP_VER and WITH_MYSQL_VER does no longer imply the corresponding WITH_ variable.

- experimental support for optionsng from devel/portmk
