SSL clients

Having a self-signed certificate at level zero is considered an error
in the OTP SSL application. That is rather silly (I did it), for then
you could not use SSL as a top CA, for instance. I will record it as
a bug to the fixed for R9. 

I attach the following certificate files so you can easily continue
testing.  The certificates are not self-signed and are used in the OTP SSL
test suites. They do work with verify = 0 (the client does not even need

	file			use for option
	----			--------------
	ssl_server.pem		certfile
	ssl_client.pem		certfile

I also attach a set of certificate and key files for true verifying.   

	file			use for option
	----			--------------
	allcacert.pem 		cacertfile
	servcert.pem		certfile
	servkey.pem		keyfile
	clntcert.pem		certfile
	clntkey.pem		keyfile	

Note however that the option `cacertfile' does not work due to a bug in
SSLeay (maybe it works in OpenSSL), so you have to set the OS environment
variable SSL_CERT_FILE to "<path>/allcacert.pem". This sad fact is 
documented in the release notes. 

For R9 I will abandon SSLeay for OpenSSL, and try to sort out the
