* 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
