	* vty.h: Remove fields in struct vty that were related to VTY_CONTINUE
	  capabilities (that were used only in bgpd/bgp_route.c and are now
	  removed).  Also remove some other fields that were not being
	  used at all.
	* vty.c: (vty_execute) Do not test for obsolete status values VTY_START
	  and VTY_CONTINUE.
	  (vty_read) Remove calls to vty->output_func since that was part
	  of the VTY_CONTINUE infrastructure that has been removed.
	  (vty_flush) Remove code to support VTY_START and VTY_CONTINUE.
	  (vty_close) Remove code to cancel vty->t_output thread, since that
	  thread was never actually used.
	* bgp_route.c: Remove all code related to VTY_CONTINUE; this feature
	  is deprecated because the output did not represent a single point
	  in time.  All output needs to be generated inline and buffered
	  by the library code.
	  (route_vty_out,route_vty_out_tag,damp_route_vty_out,
	   flap_route_vty_out) Remove code to count number of lines of output,
	   since this was only useful for VTY_CONTINUE behavior.
	  (bgp_show_callback) Removed.
	  (bgp_show_table) Remove hooks for VTY_CONTINUE callback support.
	  As a result, there's a new output_arg argument to this function.
	  Make function static.
	  (bgp_show) Make function static and add a new output_arg argument.
	  Change all functions that call bgp_show or bgp_show_table to
	  pass the new output_arg argument (that used to be passed inside
	  vty->output_arg).
	* bgp_mplsvpn.c: Remove declarations of functions defined in
	  bgp_route.c; these declarations belong in bgp_route.h.
	* bgp_route.h: Declare 3 global functions used in both bgp_route.c
	  and in bgp_mplsvpn.c.
