node_memory: Wire up the RPC protocol

* src/rpc/gendispatch.pl: (virNodeSetMemoryParameters is the
  the special one which needs a connection object as the first
  argument, improve the generator to support it).
* daemon/remote.c: (Implement the server side handler for
  virDomainGetMemoryParameters)
* src/remote/remote_driver.c: (Implement the client side handler
  for virDomainGetMemoryParameters)
* src/remote/remote_protocol.x: (New RPC procedures for the two
  new APIs and structs to represent the args and ret for it)
* src/remote_protocol-structs: Likewise
