* qemud/iptables.[ch]: add code for managing iptables
        rules.

        * qemud/Makefile.am: add iptables.[ch].

        * qemud/qemud.c: add and remove iptables rules as
        appropriate.

        * qemud/conf.c: when starting a guess, add a rule
        allowing it to forward packets across the networks
        bridge.

        * qemud/internal.h: add iptables context ptr

        * configure.in: add --with-iptables-dir and
        --with-iptables-prefix to allow us to put our rules
        in a chain with the given prefix and save the rules
        in files in the given dir so as to integrate with
        the proposed "service iptables restart" solution
        in:

           https://bugzilla.redhat.com/227011

        * src/xml.c: with <interface type="network"> connect the
        Xen guest to the appropriate bridge.

        * 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.

        * src/xend_internal.c, src/xm_internal.c: pass the
        connection to virDomainParseXMLDesc()

        * src/xml.[ch]: make virDomainParseXMLDesc accept
        a virConnectPtr so that we can use it later to
        lookup the bridge associated with a network

        * tests/xml2sexprtest.c: just pass NULL here, it's
        safe

        * qemud/conf.c: add support for connecting a qemu
        guest to a bridge using a tap device in order to
        connect it to a virtual network.

        * qemud/internal.h: add <interface type="network">
        config and track tapfds so as to not close them
        on exec.

        * qemud/qemud.c: don't close tapfds on exec and
        disconnect the iface when the guest shuts down.

        * src/conf.h: fix merge error - remove the argc argument
        from qemudBuildCommandLine()

        * qemud/conf.c, qemud/internal.h: add dhcp config

        * qemud/qemud.c: start dnsmasq to provide dns/dhcp
        for virtual networks.

        * src/virsh.c: Re-name some of the VSH_DOMBYFOO stuff
        to VSH_BYFOO in order to re-use it for the network stuff.

        * configure.in: add --disable-bridge-params, check
        for libsysfs and various kernel headers

        * bridge.[ch]: add code for managing bridges

        * qemud/Makefile.am: add bridge.[ch] and link against
        libsysfs if enabled.

        * qemud/conf.c: add support for bridge config.

        * qemud/internal.h: add various bridging bits

        * qemud/qemud.c: implement qemudStartNetworkDaemon()
        and qemudShutdownNetworkDaemon().

        * src/hash.c, src/internal.h: Re-name virConnect->domains_mux
        to virConnect->hashes_mux since it will also be used to
        protect the networks hash.

        * src/conf.c: qemudSaveConfig() will always report a
        more specific error, so we should avoid overwriting
        this error.

        * qemud/conf.[ch]: implement parsing and saving network
        configs.

        * qemud/driver.c: flesh out the stubs

        * qemud/internal.h: add networks list etc. to
        struct qemud_server

        * qemud/qemud.c: add qemudStartNetworkDaemon() and
        qemudShutdownNetworkDaemon() stubs.

        * qemud/qemud.c: Re-factor out qemudExec() so that it can
        be used to launch dnsmasq.

        * qemud/conf.c: don't return argc from qemudBuildCommandLine()
        as exec() doesn't need it.

        * 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: Re-factor bits of conf.c so that:

          - qemudMakeConfigPath() can be re-used given another configDir
          - split qemudEnsureConfigDir() out of qemudSaveConfig() so
            that it may be re-used to create another configDir
          - split qemudScanConfigDir() out so that qemudScanConfigs()
            can scan multiple configDirs

        * qemud/conf.c: handle an unspecified MAC address,
        fix the argv freeing code in qemudBuildCommandLine()
        and fix copy and paste error in qemudGenerateXML()

        * src/internal.h: add virConnect->qemud_fd so that
        xen and qemu don't share the handle member.

        * src/hash.c, src/qemu_internal.c: update

	* src/virsh.c: add the net-* commands.

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

        * conf.[ch]: rename from config.[ch] so we can use
        autoconf's config.h

        * Makefile.am: update

        * driver.c, qemud.c: upd.

        Note: potential ABI break here, but people should
        only really be using virError structs returned from
        libvirt itself.

        * include/libvirt/virterror.h: add virNetwork
        to virError

        * src/internal.h, src/virterror.c: add network param
        to __virRaiseError()

        * src/conf.c, src/hash.c, src/libvirt.c, src/proxy_internal.c,
        src/qemu_internal.c, src/sexpr.c, src/test.c, src/xen_internal.c,
        src/xend_internal.c, src/xm_internal.c, src/xml.c, src/xmlrpc.c,
        src/xs_internal.c: update.

        * include/libvirt/libvirt.h.in: add the networks APIs

        * include/libvirt/virterror.h: add some error codes

        * src/driver.h: add network driver vtable

        * src/hash.c: add networks hash

        * src/internal.h: add virNetwork

        * src/libvirt.c: hook up the APIs to the network
        driver

        * src/virterror.c: handle the new error codes

        * autogen.sh: run autoheader

        * config.h.in: remove

  in getopt_long()

        * include/libvirt/libvirt.h.in: add VIR_UUID_BUFLEN and
        VIR_UUID_STRING_BUFLEN

        * libvirt/proxy/libvirt_proxy.c, libvirt/src/hash.c,
        libvirt/src/internal.h, libvirt/src/libvirt.c,
        libvirt/src/proxy_internal.c, libvirt/src/test.c,
