Delayed loading of IMAP message parts.

	* camel-types.h: typedef CamelMessageInfo and
	CamelMessageContentInfo here

	* camel-folder-summary.h: Add a "size" field to
	CamelMessageContentInfo.

	* camel-folder-summary.c (camel_folder_summary_content_info_new,
	camel_folder_summary_content_info_free): Renamed and made
	non-static for providers that construct their own content info.
	(content_info_load, content_info_save): load/save size

	* camel-data-wrapper.c (camel_data_wrapper_is_offline): New
	function to return if a data wrapper's contents are "offline". (So
	that, for example, we don't make thumbnails of images that haven't
	been loaded off the IMAP server yet.) Defaults to FALSE.

	* providers/imap/camel-imap-folder.c (camel_imap_folder_selected):
	Fix a bug in re-selecting a folder when messages have been
	expunged from it by another client in the meantime.
	(imap_get_message): Rewrite. If the message is larger than a
	certain size, just create a skeleton message containing
	CamelImapWrappers that will read parts as needed. This way, large
	attachments only need to be downloaded if the user looks at them,
	and multipart/alternative alternatives that aren't used will never
	be downloaded at all.
	(imap_update_summary): Rewrite this a bunch too to make the
	parsing more robust.

	* providers/imap/camel-imap-summary.c
	(CAMEL_IMAP_SUMMARY_VERSION): bump.
	(camel_imap_summary_new): Set build_content to TRUE.
	(content_info_load, content_info_save): Only save/load the content
	for messages that have it. (The content info gets created as a
	side effect of imap_get_message.)

	* providers/imap/camel-imap-utils.c (imap_parse_body): New routine
	(and helpers) to parse an IMAP 'body' FETCH response and fill in a
	CamelMessageContentInfo from it.

	* providers/imap/Makefile.am (libcamelimap_la_SOURCES,
	libcamelimap_la_HEADERS): add camel-imap-wrapper.
