Remove the "status" field from here, since it's mostly used by

	* libsoup/soup-message-private.h (SoupMessagePrivate): Remove the
	"status" field from here, since it's mostly used by SoupSession,
	which shouldn't need access to SoupMessagePrivate.

	* libsoup/soup-message.h (SoupMessage): Move it here.
	(SoupCallbackFn): Remove this alias for SoupMessageCallbackFn.
	(soup_message_set_uri): also moved from soup-message-private.h

	* libsoup/soup-message.c: s/msg->priv->status/msg->status/.

	* libsoup/soup-message-handlers.c:
	s/SoupCallbackFn/SoupMessageCallbackFn/ everywhere.

	* libsoup/soup-message-io.c (soup_message_io_client,
	soup_message_io_server, soup_message_io_unpause): Don't set up an
	idle handler, just jump right in to reading/writing; if this is a
	synchronous socket, then the caller wants to block, and if it's
	not, then we'll quickly get an EAGAIN anyway.

	* libsoup/soup-session.c: (queue_message): Likewise.
	(*) Update for SoupMessageStatus move and remove
	soup-message-private.h include.

	* libsoup/soup-server-message.c: Remove soup-message-private.h
	include.

	* libsoup/soup-server.c: Likewise.

	* libsoup/soup-connection.c (soup_connection_is_connected,
	soup_connection_is_new): Remove these, since they weren't being
	used.

	* libsoup/soup-md5-utils.c: Moved from md5-utils.c and renamed, to
	avoid namespace pollution.

	* libsoup/soup-auth-digest.c: Update for that.
	* libsoup/soup-server-auth.c: Likewise

	* tests/auth-test.c: Remove soup-message-private.h include
