To facilitate creation of new clients using XDR RPC services, pull alot of the remote driver code into a set of reusable

objects.
- virNetClient: Encapsulates a socket connection to a remote RPC server. Handles all the network I/O for reading/writing RPC messages. Delegates RPC encoding and decoding to the registered programs
- virNetClientProgram: Handles processing and dispatch of RPC messages for a single RPC (program,version). A program can register to receive async events from a client
- virNetClientStream: Handles generic I/O stream integration to RPC layer
Each new client program now merely needs to define the list of RPC procedures & events it wants and their handlers. It does not need to deal with any of the network I/O functionality at all.

A few places throughout this series, I've noticed double-spaces mid-sentence in comments. Not fatal, but might be worth a cleanup pass later on. Looks like a reasonable refactoring overall; most of the code seems to be copied from elsewhere already existing (so I'm assuming later patches clean up existing code to use these new objects).
