Bugfix (introduced: Postfix 2.6): the Milter SMFIR_CHGFROM
(replace sender) request lost the sender_bcc_maps address.
Fixed by moving some record keeping to the sender output
function.  Files: cleanup/cleanup_envelope.c,
cleanup/cleanup_addr.c, cleanup/cleanup_milter.c,
cleanup/cleanup.h, regression tests.

Bugfix (introduced: Postfix 2.6): the "bad filetype"
header_checks pattern falsely rejected Content-Mumble headers
with ``name="example"; x-apple-part-url="example.com"''.
Fixed by respecting the ";" separator between content
attribute values.  Reported by Cedric Knight.  File:
proto/header_checks.

Portability: OpenBSD 6.0. Files: makedefs, util/sys_defs.h.
