don't leak the SoupAddress.

don't leak the SoupAddress.

	* libsoup/soup-connection.c (soup_connection_connect_async): don't
	leak the SoupAddress.

	* libsoup/soup-dns.c (soup_dns_lookup_resolve_async): fix a leak
	when re-looking up an address

	* libsoup/soup-session.c (soup_session_abort): close all
	connections in addition to cancelling messages (needed because
	connections currently end up holding a ref on their session,
	preventing them from being destroyed).

	* tests/auth-test.c:
	* tests/ntlm-test.c:
	* tests/proxy-test.c:
	* tests/pull-api.c:
	* tests/ssl-test.c:
	* tests/xmlrpc-test.c: clean up more memory on exit, to help find
	leaks in the library

	* tests/libsoup.supp: add a zillion new suppressions so we
	can use --leak-resolution=med
