MERGE NEW_PARSER branch into HEAD, fixed conflicts.
2000-04-20 NotZed <NotZed@HelixCode.com> * MERGE NEW_PARSER branch into HEAD, fixed conflicts. * gmime-content-field.c (_print_parameter): Duh, removed again (@@#$@ cvs merge). * camel-mime-utils.c (header_content_type_is): Constify. (header_content_type_unref): Killed a couple warnings. * camel-folder.c (_init): Removed more log crap. * providers/Makefile.am (SUBDIRS): Removed nntp, pending fixes for summary changes. * providers/mbox/camel-mbox-folder.c (_get_message_by_number): Fixed for new summary interface. Added a warning for using this broken api. (_get_message_by_uid): Fixed for message new with session vanishing. svn path=/trunk/; revision=2531
