      Add tb-set-uselinkdelays to switch between normal delay nodes and · 46155476

      link delays setup on the nodes.
      
      Add tb-set-forcelinkdelays to force a linkdelay (when uselinkdelays is
      on of course) to be inserted, even if the link was unshaped. This
      allows it to be controlled later, say via the event system. This is
      nice, cause in the current system an unshaped link cannot be later
      shaped.
      
      Note that these are currently require FBSD-47.

      Allow slightly altered tb-fix-node syntax for creating jails on local · d564e0fb

      nodes. The second argument can now be an NS node instead of the name
      of a real testbed node. For example:
      
      	tb-set-hardware $node3  pc600
      	tb-set-hardware $nodev1 pcvm600
      	tb-fix-node $nodev1 $node3
      
      So, "fix" $nodev1 to $node3. The intent is that once $node3 is
      allocated by assign to a real testbed node, we can then allocate a
      virtual node on pcXX to $nodev1. I did this primarily to allow for
      easy testing of jails via my NS file, without having to hack assign
      wrapper to deeply. Note there are still hacks in assign_wrapper to
      support this, but they are not extensive.
      
      Also my old usewatunnels stuff I never checked in:

      NSE related changes: · 05bc3bd4
      Shashi Guruprasad authored
        - Fixes the routing problem
        - A new type "sim" has been created but not in the DB. node_types and
          nodes remain unchanged. This will change after we figure out how
          to represent in the DB the local multiple virtnodes in one phynode case
          The frontend tb_compat.tcl adds the sim type and ptopgen associates
          a huge number of sim nodes to all local PCs.
        - All simulated nodes go into one pc untill I finish coding the distributed
          nse case. Also, sim nodes go through assign but with an explicit
          "fix-node" directive in the top file. A random free pc is chosen using
          the avail script in assign_wrapper. If we don't fix node it, assign
          maps sim nodes to multiple phy nodes even when a valid all to one
          mapping is possible.
        - Syntax for nse:
      
         $ns make-simulated {
      
             set simnode1 [$ns node]
             set simnode2 [$ns node]
      
         }
         ...
      
         The old syntax
      
         set nsenode [$ns nsenode]
         $nsenode make-simulated {
         }
      
         is deprecated
      
        - All 38 frontend tests in the testsuite pass
      
        - A new table v2pmap has been added to handle multiple virt nodes to
          one phy node mapping. This is used in "tmcc hostnames" currently.
      
        - The phy node that is picked to run nse is loaded with a custom image
          FBSD45-NSE . This can use the default FBSD kernel if there is a mechanism
          to run at 1000HZ, have options IPFIREWALL_FORWARD and PERFMON turned on.
          The image is in the 'testbed' group. Do not delete this image.
      
        - Static routes now adds routes for the case dst == nexthop. The routing
          graph would be disconnected otherwise and I need to traverse this in
          assign_wrapper for nse. On the client side, such a route is filtered out in
          libsetup.pm
      
        - sim nodes are also correctly visualized

      Complete rewrite.  Includes a great deal more documentation including a
      description of IP allocation.  Also uses the new format.
      
      Note: The section on tb-create-os is unfinished.  I need some info from
      Leigh, then I'll fix it up.
      
      tb_compat.tcl
      
      The NOP version of tb_compat.tcl that users should download to run their
      scripts with NS.  There is a link to this file in nscommands.html.

      parse.tcl has a few minor fixes and copies in the tb_compat.tcl file now. · 8b418535
      Christopher Alfeld authored
      postparse now uses tbcmds
      sim.tcl is updated to close (and flush) the tbcmds output stream if it
      exists.
      tb_compat.tcl is the TB version that should be included by newstyle ns scripts.
      tb_compat_nop.tcl is the NS version that should be renamed to tb_compat.tcl
      and included by scripts when they are run under ns.  I.e. scripts
      	source tb_compat.tcl
      as the first line and then use either the TB or the NS (nop) version depending
      on what they are doing.
