* src/bridge.c, src/bridge.h, src/qemu_conf.c, src/qemu_conf.h,
	  src/qemu_driver.c, src/qemu_driver.h, src/test.c: Disable more
	  of qemu if configured --without-qemu.

        Avoid risk of format string abuse (also avoids gcc warnings).
        * src/util.c (ReportError): Use a literal "%s" format string.
        * src/remote_internal.c (server_error): Likewise.
        * src/qemu_conf.c (qemudReportError): Likewise.
        * acinclude.m4: Add -Wformat -Wformat-security to default
          list of warning flags, to warn about errors such as the
          above.

        * acinclude.m4, configure.in: ./configure option
          --disable-stack-protector.
        * src/gnutls_1_0_compat.h: Compatibility with GnuTLS 1.0.
        * src/bridge.c: If no bridge ioctls, give an error at runtime.

  features for i686 and x86_64, patch from David Lutterkort
Daniel

	* 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.

        * qemud/iptables.c: Remove the target interface parameter
        from iptablesPhysdevForward(). This rule is intended to
        allow frames to be forwarded across the bridge from the
        supplied bridge port. In this context, the --out parameter
        would match the outgoing bridge port, which will never
        be network->def->forwardDev.

  replaced all sprintf instances by snprintf ones

  src/sexpr.h src/test.c src/xm_internal.c src/xml.c src/xml.h:
  applied patch from Richard Jones adding check to printf-like
  functions and fixing the problems raised
