correct parameter decl (const)

1999-09-07  bertrand  <Bertrand.Guiheneuf@aful.org>

	* camel/md5-utils.c (md5_get_digest_from_file):
	correct parameter decl (const)

	* camel/md5-utils.h: typo.

	* camel/providers/MH/mh-uid.c
	More work on UID stuff for MH.
	(mh_save_uid_list):
	(mh_load_uid_list):
	(mh_generate_uid_list):
	new funcs. Manage on-disk uid list.

	* camel/providers/MH/mh-utils.c (mh_is_a_message_file):
	Util routines live here now.
