(vm-use-spam-filter)

(rsf-min-region-length-added-to-spam-list): New	variables.
(rsf-bbdb-auto-delete-spam-bbdb-entries): Renamed from
rmail-bbdb-auto-delete-spam-entries.  Added cc: to recipients for
spam testing.  Don't delete spam message if automatic deletion
after output via variable rmail-delete-after-output is turned on.
(rsf-bbdb-dont-create-entries-for-deleted-messages): Renamed from
rsf-bbdb-dont-create-entries-for-spam.
(check-field): New function, extracted from code in
rmail-spam-filter to ease addition of header fields like
content-type.
(message-content-type): New variable to check the content-type:
field added, also in defcustom of rsf-definitions-alist.
(rmail-spam-filter): Replace repeated test code for header fields
by calls to check-field; change the call to
rmail-output-to-rmail-file such that rmail-current-message stays
the same to avoid wrong deletion of unseen flags.
(rsf-add-contents-type): New function to convert old format
of rmail-spam-definitions-alist into new one.
Changed prefixes of all variables and functions from
rmail-spam-filter- or spam-filter- or rmail-spam- to rsf-.
