Implement RFC 5077 Session Tickets

[ryhaberecht]

BouncyCastle still does not really support RFC 5077, half of it is missing. Someone apparently already wrote a fix for this, but never came around to a PR: http://bouncy-castle.1462172.n4.nabble.com/RFC-5077-SESSION-TICKETS-td4657411.html

Thanks for bringing the patch back to our attention, I'll take a look.

Hi. I am that "someone". I will send a pull request for review.

[partheinstein]

Assuming we want backwards compatibility, I guess I shouldn't use any Java8 features like default methods. Right?

[peterdettman]

Yes, please try to avoid "fancy" language features.

[partheinstein]

I am using Eclipse to write Java code. Is there a code formatting template that I should conform to?

[partheinstein]

I've submitted a pull request: #126

[ryhaberecht]

Pull request still not accepted. Is this because TLS 1.3 will obsolete RFC 5077? Maybe we should rework the patch to conform to TLS 1.3 instead?
