	* camel-tcp-stream-openssl.c (ssl_verify): use
	X509_STORE_CTX_get_ex_data to get at the SSL* - don't use the
	X509_STORE_CTX to look up our stream, since it's not what we used
	to insert our stream into the hashtable.
	(open_ssl_connection): insert the stream into the hashtable before
	calling SSL_connect, as this can cause ssl_verify to be called,
	and we need to look up the stream there.  remove the stream from
	the hashtable if there's an error connecting.
	(stream_connect): pass the CamelTcpStreamOpenSSL* to
	open_ssl_connection since it handles the hashtable stuff.  remove
	hashtable stuff from here.
