Patch by Vinay R <rvinay@novell.com> and Robert Love <rml@novell.com>,
	to add support for per-route MSS and improve support for per-interface
	MTU:
	* src/NetworkManagerSystem.c: Modify nm_system_device_set_ip4_route to
	  optionally take an MSS parameter and set it for the given route.
	  Remove nm_system_device_set_ip4_route_with_iface.  Pass in the
	  NMIP4Config's stored MSS, if any.
	* src/nm-ip4-config.c: Add 'mtu' and 'mss' to NMIP4Config, representing
	  the interface's MTU and the route's MSS, respectively.  Add functions
	  nm_ip4_config_get_mtu, nm_ip4_config_set_mtu, nm_ip4_config_get_mss,
	  and nm_ip4_config_set_mss for retrieving and setting the MTU and the
	  MSS.
	* src/nm-ip4-config.h: Add prototypes for nm_ip4_config_get_mtu,
	  nm_ip4_config_set_mtu, nm_ip4_config_get_mss, and
	  nm_ip4_config_set_mss.
	* src/vpn-manager/nm-vpn-service.c: Modify to receive the MSS from the
	  VPN daemon.
	* src/backends/NetworkManager{Arch,Debian,Gentoo,RedHat,Slackware,SUSE}.c:
	  Change the retval of nm_system_get_mtu to guint32.
	* src/dhcp-manager/nm-dhcp-manager.c: Set the MTU on the new DHCP-given
	  NMIP4Config to the MTU provided by the system, if any.  TODO: If DHCP
	  servers can specify MTU's, we should set it here if the MTU was not
	  provided.
