[Click] ns2 traces - ToNSTrace patch

[Michael Voorhaen]

Hi Eddie,

In attachment are some patches for click and nsclick to add tracing from click 
to ns2 compatible traces. Example tcl files are also attached to show how the 
element (ToNSTrace) can be used (tonstrace.click, tonstrace.tcl). A ns2 trace 
file called tonstrace.tr is generated.

The patch files:
tonstrace.click.patch (the patch for click_cvs)
tonstrace.nsclick.patch (the patch for nsclick: ns-2.29 + nsclick patch 
already applied)
tonstrace.ns-2.29.patch (an updated version of ns-2.29.patch)

The last patch also includes a small fix for ns-2.29/tcl/lib/ns-clicknode.tcl 
that makes sure that the node is also added to the channel object in ns2. 
This fixes a segmentation fault related to wireless scenarios where the 
GridKeeper object is not used.

Regards,
Michael
