	* (global) more const'ification and fixups of types to clean up code.
	* bgp_mplsvpn.{c,h}: (str2tag) fix abuse. Still not perfect,
          should use something like the VTY_GET_INTEGER macro, but without
          the vty_out bits..
        * bgp_routemap.c: (set_aggregator_as) use VTY_GET_INTEGER_RANGE
          (no_set_aggregator_as) ditto.
        * bgpd.c: (peer_uptime) fix unlikely bug, where no buffer is
          returned, add comments about troublesome return value.
