As the start of work to add remote support, I'm taking a close look at the protocol layer in the library. These are some small cleanups. Rich.

I've been taking a long hard look at the protocol layer. It has evolved over a long time without any particular direction, and the result is, to say the least, not very organized. These patches take a first step at cleaning up the mess by abstracting out socket operations from the rest of the code. The purpose of this is to allow us to slot in a different connection layer under the
