this off, but here is what I did.

Parser: Allow for the following syntax

	set link0  [$ns duplex-link $nodeA $nodeB 100Mb 0ms RED]
	set queue0 [[$ns link $nodeA $nodeB] queue]
	$queue0 set gentle_ 1
	$queue0 set queue-in-bytes_ 0
	$queue0 set limit_ 50
	$queue0 set maxthresh_ 20
	$queue0 set thresh_ 7
	$queue0 set linterm_ 11
	$queue0 set q_weight_ 0.004

    NB: This differs from the NS syntax (and is the part that Chris
    needs to fix) in that there is just a single queue object per
    duplex link, thus the parameters cannot be set asymmetrically.
    Note, the delay node *does* use a RED/GRED queue in each
    direction, but its params are the same. These TCL hacks took a
    long time for me to get right!

    Also note that I have no idea how this stuff relates to LANS! I
    do not allow LANS to be created with RED queues (another item for
    Chris to work on perhaps?).

assign_wrapper: A horrible hack to pass the new fields added to
virt_lans onto the delays table setup. Also another minor hack ensure
that a delay node is added when a RED queue is used (for the case when
no other traffic shaping is done). At the moment, the virt_lans table
has a single set of fields, while the delays table has the double set;
one for each direction of the pipe. Here is a listing.

    alter table delays add q0_limit int default 0 after lossrate0;
    alter table delays add q0_maxthresh int default 0 after q0_limit;
    alter table delays add q0_minthresh int default 0 after q0_maxthresh;
    alter table delays add q0_weight float default 0.0 after q0_minthresh;
    alter table delays add q0_linterm int default 0 after q0_weight;
    alter table delays add q0_qinbytes tinyint default 0 after q0_linterm;
    alter table delays add q0_bytes tinyint default 0 after q0_qinbytes;
    alter table delays add q0_meanpsize int default 0 after q0_bytes;
    alter table delays add q0_wait int default 0 after q0_meanpsize;
    alter table delays add q0_setbit int default 0 after q0_wait;
    alter table delays add q0_droptail int default 0 after q0_setbit;
    alter table delays add q0_red tinyint default 0 after q0_droptail;
    alter table delays add q0_gentle tinyint default 0 after q0_red;

tmcd/tmcd.c: Change dodelays to pass back all of these fields (for
both pipes; there are equiv q1 fields in the delays table). Yikes! Its
done in a backwards compatable manner though, so existing delay nodes
will continue to work just fine.

tmcd/freebsd/liblocsetup.pm: Change the delays configuration script to
get all these fields and do something useful with. Of course, our
delay nodes cannot use a lot of these fields, but the information is
sent through for the eventuality that we have more sophisticated
delays nodes.

Test Suite: Add red test dir that has the above syntax as its test.
