hold separate values for each of the two pipes. This allows us to treat the links asymmetrically with respect to the delay node configuration. Changes to tmcd to return the expanded info, and rework (completely) delay_config to allow user to change the duplex characteristics (just like before), or just simplex characteristics by specifying the pipe number. By convention (I invented) pipe 0 is traffic coming in on iface0. Of course, none of the front end stuff has been changed, so the changing a single pipe does not cause anything in virt_lans to be changed, so those changes will be lost at swapout. Also get rid of all the ssh'ed pipe config stuff in delay_config. Instead, add a client side script called update_delays to /etc/testbed on the experiment nodes. After updating the delays table, just ssh over and run that script, which calls the existing code. Less distribution of knowledge.
