Standardise server structure

[coffeepots]

Ensure all server functions conform to an agreed signature.
For example:

• init()
• start()
• pause()
• resume()
• stop()
• shutdown()

Currently we have different nomenclature for different operations within the two existing servers (for example I'm using serve() instead of start().

@zah, @yglukhov We'll need to settle on these as soon as possible.
For the record, I'm happy with the above, suggested by @cheatfate
