Introduces an API for encoding the header field for outgoing messages
allowing some duplicated code to be eliminated

* qemud/dispatch.c, qemud/dispatch.h: add remoteEncodeClientMessageHeader
  for encoding message header. Update remoteDispatchClientRequest to
  use this method.
* qemud/remote.c: Update remoteDispatchDomainEventSend to use the
  generic remoteEncodeClientMessageHeader() for encoding event
  message hedaders. Push some logic from remoteRelayDomainEvent
  down into remoteDispatchDomainEventSend.

Separate the decoding of incoming request header out from the
dispatch code. This will allow later code to making dispatcher
routing decisions based on the header field data.

* qemud/dispatch.c, qemud/dispatch.h: Add remoteDecodeClientMessageHeader
  API for decoding the header of a client message. Update the
  remoteDispatchClientRequest method to assume a pre-decoded
  header.
* qemud/qemud.h: Include a 'remote_message_header' field in
  'struct qemud_client_message' for pre-decoded header data
* qemud/qemud.c: Decode the incoming client message header before
  invoking remoteDispatchClientRequest

* po/POTFILES.in: Add qemud/dispatch.c
* qemud/dispatch.c, qemud/dispatch.h: Generic code handling dispatch of
  RPC messages.
* qemud/Makefile.am: Add dispatch.c to build
* qemud/qemud.c: Include dispatch.h
* qemud/qemud.h: Remove remoteDispatchClientRequest, remoteRelayDomainEvent
  now in dispatch.h
* qemud/remote.c: Remove remoteDispatchClientRequest, remoteRelayDomainEvent
  now in dispatch.c, and dispatch_args, dispatch_ret, dispatch_fn & dispatch_data
  now in remote.h
* qemud/remote.h: Add typedefs for dispatch_args, dispatch_ret,
  dispatch_fn, dispath_data. Add remoteGetDispatchData() API

	* qemud/Makefile.am, qemud/dispatch.c, qemud/dispatch.h,
	  qemud/internal.h, qemud/protocol.c,
	  qemud/protocol.h, qemud/protocol.x, qemud/qemud.c:
	  libvirt_qemud server-side modifications to use
	  XDR-based protocol instead of homebrew (Dan Berrange).
	  QEMUD server modified to dispatch calls from remote
	  clients (Richard Jones).  Added TLS support (Richard Jones).
	  Added TCP & IPv6 support (Richard Jones).
	  Additional configuration file, command-line handling, and
	  usage (Richard Jones).
	* qemud/conf.c: Remove unnecessary header file.

* docs/*: fixed the api extractor script and regenerated
Daniel

        * qemud/protocol.h: add the (domain/network)(Get/Set)Autostart
        requests and replies to the protocol.

        * src/qemu_internal.c: hookup the qemu driver autostart
        methods

        * qemud/dispatch.c, qemud/driver.[ch], internal.h: add
        the daemon side, but just set an in-memory autostart
        flag for now.

        * qemud/driver.[ch], qemud/dispatch.c: fix the fact that
        qemudDispatchDomainStart() doesn't report an error if the uuid
        lookup fails and also move the uuid lookup into the driver
        so that it matches the way we do Destroy().

        * qemud/qemud.c, qemud/dispatch.c, qemud/internal.h
        qemud/conf.c, qemud/driver.c, configure.in: add a
        qemudLog() function which uses syslog() if we're in daemon
        mode, doesn't output INFO/DEBUG messages unless the
        verbose flag is set and doesn't output DEBUG messages
        unless compiled with --enable-debug. Also, make a first
        pass through fatal errors and add error messages for them.

	* qemud/conf.[ch], qemud/dispatch.c, qemud/internal.h,
	  qemud/qemud.c, qemud/driver.c: allow re-defining network
	configs; basically copying dan's patch for domains.

        * include/libvirt/libvirt.h.in, src/libvirt.c: add
        virNetworkGetBridgeName() to allow finding out what
        bridge to connect to in order to join a network.

        * src/driver.h: add networkGetBridgeName() to vtable.

        * qemud/protocol.h: add the request and reply to
        the qemud protocol.

        * qemud/dispatch.c, qemud/driver.[ch]: handle them
        here.

        * src/qemu_internal.c: implement GetBridgeName()
        in the qemu driver.

        * src/libvirt_sym.version: add new symbol.

        * qemud/protocol.h: add the protocol for virtual networks

        * qemud/dispatch.c: implement the protocol

        * qemud/driver.[ch]: add stubs for the driver

        * qemud/internal.h: add struct qemud_network

        * src/qemu_internal.c: add a virtual networks driver

        * qemud/conf.c, qemud/dispatch.c, qemud/driver.c,
          qemud/qemud.c: include autoconf's config.h
