[Development] TLS extensions and supplemental data

[Scott Deboy]

I wanted to give folks a heads-up that I'm starting work on defining an API which will give Qt the ability to retrieve and set TLS extension data sent in OpenSSL's extended hello.  

I will also be adding support for the ability to send and retrieve supplemental data messages.

A Wiki topic has been created to work through the process of defining the API - please feel free to update/add questions or contribute to the discussion:

Thanks much,

Scott
