Added camel-imap-utils.[c,h]

2000-07-27  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/Makefile.am: Added camel-imap-utils.[c,h]

	* providers/imap/camel-imap-utils.[c,h]: Utilities for parsing
	server responses for use in both camel-imap-store.c and
	camel-imap-folder.c

	* providers/imap/camel-imap-folder.c (imap_get_summary_internal):
	Free all the pointers in the headers array.
	(imap_get_subfolder_names_internal): Updated to use
	imap_parse_list_response
	(imap_parse_subfolder_list): Removed in favor of
	imap_parse_list_response

	* providers/imap/camel-imap-store.c (camel_imap_command_extended):
	Free all the pointers in the data array.
	(imap_connect): Updated to use imap_parse_list_response and fixed
	a leak
	(folder_is_selectable): Updated.
