        NpgsqlTypes/NpgsqlTypesHelper.cs : - store protocol version as an enum, keep numbers as protocol specific
        - split more protocol handlers between version 2 and version 3
        - split MessageTypes class on ver2/ver3 and add remaining types for ver3        - removed handlers for deprecated protocol message types
        - store BackendKeyData in its own member on Mediator
        - Store ParameterStatus objects in a key map on Mediator
        - Get backend version now from the Mediator if possible
        - Rewrite parsers for server version and connection string
        - Store server version numericially (in a new class ServerVersion)
        - As usual, lots of code cleanup/commenting/etc.

        Thanks very much Glen Parker (glenebob@nwlink.com) for this patch.
