New function to copy a header_references structure.

	* camel-mime-utils.c (header_references_dup): New function to copy
	a header_references structure.

	* camel-folder-summary.c (camel_message_info_dup_to): New function
	to (deep) copy the data from one CamelMessageInfo into another.
	(camel_message_info_free): And free the data.

	* providers/vee/camel-vee-folder.c (vee_sync): Implement. (empty).
	(vee_search_by_expression): belatedly update for
	camel_folder_search change.
	(vee_folder_build): belatedly update for camel_folder_search
	change. Use camel_message_info_dup_to and camel_message_info_free
	(in particular, so that we get message_id and references info so
	vfolders can be threaded).
	(vee_folder_build_folder): Ditto.
