  Add generated messages that can work without using IPC::Connection

Reviewed by Alex Christensen and Chris Dumez.

We want to auto generated messages to our daemons, but they don't use IPC::Connection.

This patch gives generated messages and message handlers the ability to bypass using IPC::Connection.

The MessageSender implements a few new custom methods to take a completed Encoder and ship it across its
own transport, as well as create a Decoder for replies.
The MessageReceiver implements a custom method to create its own Encoder from tranport and its own reply
handler that will be called by automatically generated code.

This just lays the groundwork and exercises it using the script tests.

Coming up next will be generating messages for webpushd
