Lib Cleaning - Cleaning up internal API

[mblenczewski]

Affecting mainly Connection.cs and UdpConnection.cs (that ive seen so far). In internal methods there are remenants of a write lock (in parameters and unused fields or properties). Im assuming this is from the now-obsolete connection locking feature. These should be removed (or at least marked Obsolete) for the next release, so as to simplify and clean up the internal API.
