add gobject-2.0 to the PKG_CHECK_MODULES call

	* configure.in (GLIB): add gobject-2.0 to the PKG_CHECK_MODULES
	call

	* libsoup/soup-address.c: Make this a GObject.
	(soup_address_ref, soup_address_unref): Gone.
	(soup_address_copy): Gone. Wasn't being used anyway.

	* libsoup/soup-dns.c: Move all of the DNS code and caching stuff
	here from soup-address.c, so that soup-address doesn't need to
	worry about trying to cache zero-ref addresses.

	* libsoup/soup-socket.c: Make this a GObject. Use "guint"
	consistently for port numbers.
	(soup_socket_ref, soup_socket_unref): Gone.

	* libsoup/soup-private.h: Change the SoupSocket definition to be
	SoupSocketPrivate. (Still need to keep this here since soup-server
	pokes around in its internals.)
	(SOUP_MAKE_TYPE): Copied from gal's E_MAKE_TYPE.

	* libsoup/soup-server.c (read_done_cb, write_done_cb): Unref the
	reader/writer rather than leaking them.

	* libsoup/*: Use GObject methods for socket/address refcounting

	* tests/auth-test.c (main)
	* tests/timeserver.c (main): Call g_type_init.

	* tests/get.c (main): Call g_type_init.
	(get_url, got_url): Fix some bugs that could make -r mode get into
	infinite loops downloading the same files over and over. Plug some
	memory leaks to make this more useful for valgrinding libsoup.

	* tests/simple-httpd.c (main): Call g_type_init. Set up a signal
	handler for SIGINT so we can exit cleanly, since valgrind won't
	give a leak report if you don't. Plug a few memory leaks.

	* tests/simple-proxy.c (main): Likewise
