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

        * qemud/default-network.xml: add a default network

        * qemud/Makefile.am: install it, and the autostart symlink

        * libvirt.spec.in: update

        * qemud/qemud.c: don't try and listen to a null socket
        path when run as a session daemon. Noticed by Rich Jones

        * qemud/driver.c: fix a couple of invalid free() calls

        * acinclude.m4: add LIBVIRT_COMPILE_WARNINGS, copied from
        GNOME but with a few more flags we'd been using.

        * configure.in: use that instead of setting CFLAGS
        directly.

        * proxy/Makefile.am, python/Makefile.am, qemud/Makefile.am,
          src/Makefile.am, tests/Makefile.am: use $(WARN_CFLAGS)

        * qemud/conf.c, qemud/uuid.[ch]: move qemudParseUUID()
        into uuid.c

        * qemud/uuid.[ch]: add uuid generation code

        * qemud/Makefile.am: build it

        * qemud/conf.c: generate a UUID if not specified in the XML

        * qemud/conf.c: qemudAutostartConfigs(): print the detailed
        error message from a guest/network autostart failure.

        * qemud/conf.c: check for malloc failure in GenerateXML()
        and GenerateNetworkXML()

        * qemud/driver.c: free the XML output after returning it
        from the DumpXML() commands.

        * qemud/conf.c: don't load config files unless they have
        a ".xml" suffix, e.g. backup files ... we spew a warning
        later if we do.

        * qemud/libvirtd.in: add init script for libvirt_qemud

        * qemud/Makefile.am: install it unless we were configured
        with --with-init-scripts=none

        * configure.in: add --with-init-scripts to allow us
        have different flavour init scripts

        * qemud/qemud.c: add --pid-file and default to writing
        out a PID file to /var/run/libvirt_qemud.pid in daemon
        mode.

        * configure.in: add --with-pid-file arg

        * qemud/Makefile.am: install libvirt_qemud in /usr/sbin
        instead of /usr/libexec

        * src/Makefile.am, src/qemu_internal.c: pass the correct
        path to libvirt

        * qemud/conf.c: actually autostart guests/networks at startup
        as appropriate.

        * qemud/internal.h: put the config directory paths in
        an array in order to make them easier to initialize,
        but still expose pointers to each of them as members
        in the server struct.

        * qemud/qemud.c: cleanup the config directory path
        initialization.

        * qemud/driver.c: maintain the autostart flag on disk
        using symlinks from the "autostart" directories to
        the corresponding config files.

        * qemud/internal.h: add paths to the autostart links
        to the vm/network structures and paths to the autostart
        dirs to the server struct.

        * qemud/qemud.c: initialize the server autostart dir
        patches.

        * qemud/conf.h: expose qemudEnsureDir()

        * qemud/conf.c: check the autostart symlinks when
        loading config files at startup.

        * 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/conf.[ch]: significantly re-factor qemudLoadConfigXML()
        so that "parse the XML", "assign the def to a VM" and
        "save the XML" operations are in separate functions.
        Add qemudRemoveInactiveVM() and qemudRemoveInactiveNetwork().
        Report errors when loading config files at startup. Check
        that a domain/network's name matches the config filename.

        * qemud/driver.c: update the Create() and Define() functions
        to explicitly parse/assign/save. Also, fix bug where if
        Create() failed, we would free the VM without removing it
        from the inactive list.

        * qemud/qemud.c: use qemudRemoveInactiveVM/Network()

        * 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/conf.c, qemud/driver.c, qemud/internal.h,
        qemud/qemud.c: Merge the ->activevms and ->inactivevms
        into a single ->vms list in order to make things
        easier to manage. Likewise for networks. Also add
        qemudIsActiveVM() and qemudIsActiveNetwork() inline
        functions.
