	Fixes for GnuTLS support on Win32. #528752, patch from Marc Maurer

	* libsoup/soup-gnutls.c (soup_ssl_wrap_iochannel): add an argument
	saying whether or not the socket is non-blocking, since there's no
	way to determine this from the fd in WinSock.
	(do_handshake, soup_gnutls_read, soup_gnutls_write): Update for
	that.

	* libsoup/soup-socket.c (soup_socket_start_proxy_ssl): Update for
	that

	* libsoup/soup-nossl.c (soup_ssl_wrap_iochannel): update the
	declaration here too

	* tests/ssl-test.c: Some updates to get this closer to working on
	Windows...
