Prevent folders from appearing to have -1 new messages. Prevent nonactive

2001-07-03  Peter Williams  <peterw@ximian.com>

	Prevent folders from appearing to have -1 new messages. Prevent
	nonactive folders from updating the title bar. Make the title
	bar update when switching to an already-opened folder.

	* mail-folder-cache.c (update_message_counts): Ignore the value for
	'unread' if it is -1.
	(get_mail_info_receive): Same
	(mail_folder_cache_note_folderinfo): Same.
	(get_folder_info): Initialize 'fb' to NULL.
	(mail_folder_info): Add 'fb' member.
	(mail_folder_cache_note_fb): Change note_message_list to this.
	(update_idle): Only update the ShellView if the active folder browser
	is the same as the one that the MFI references.
	(mail_folder_cache_set_folder_browser): New function. Use it to set
	the active folder browser. NULL is okay.
	(check_for_fb_match): Called from the above. If the MFI has the
	new folder browser as its view, queue an update.

	* mail-folder-cache.h: Fix prototypes.

	* mail-callbacks.c (create_folders): Check if fi->url is nonnull.

	* folder-browser.c (got_folder): Change to use note_fb instead of
	note_messge_list.

	* folder-browser-factory.c (control_activate): Set the folder browser
	(control_deactivate): Clear it here.
	(fb_get_svi): Kill some inappropriately cut-n-pasted code.
