New API for doing socket IO. Works both synchronously and asynchronously,

	* libsoup/soup-socket.c (soup_socket_read,
	soup_socket_read_until, soup_socket_write): New API for doing
	socket IO. Works both synchronously and asynchronously, and
	buffers data to prevent the "100 Continue" problem.
	(soup_socket_set_flag): Replaces formerly-private
	soup_set_sockopts. (primarily to let the caller turn off
	SOUP_SOCKET_FLAG_NONBLOCKING).

	* libsoup/soup-transfer.c (soup_transfer_read,
	soup_transfer_write, soup_transfer_write_simple): Take a
	SoupSocket instead of a GIOChannel. Use the new socket IO api.
	Changed the prototypes of some of the callbacks to be less
	hackish.

	* libsoup/soup-connection.c (soup_connection_get_socket): Replaces
	soup_connection_get_iochannel.

	* libsoup/soup-message.c: Fix up for soup-transfer changes

	* libsoup/soup-queue.c: Likewise

	* libsoup/soup-server.c: Likewise

	* tests/revserver.c: A slightly more complicated replacement for
	timeserver. (Does both reads and writes)
