	* libsoup/soup-message-client-io.c (parse_response_headers): if we
	receive an HTTP/1.0 response to an HTTP/1.1 request, downgrade the
	message's http_version so the keep-alive handling is correct.
	Fixes a problem noticed almost simultaneously by Rodrigo and Joe.

	* libsoup/soup-message.c (soup_message_restarted, etc): Add a
	"restarted" signal as suggested by Joe.

	* libsoup/soup-message-io.c (soup_message_io_finished): emit

	"restarted" and run the queue if a message gets restarted

	* libsoup/soup-status.h: Remove a stray comma that gtk-doc doesn't
	like.
