re: new nsallinone version

[Haobo Yu <haoboy@isi.edu>]

Did you try to build a debug version of ns and use a debugger to see where
the segv happens? If my guess is correct, it happens in trace.cc,
Trace::format() and DequeueTrace::recv(). Check for "sname" in those
functions, and change the following lines: 

		if (strcmp(name,"SRM") == 0 || strcmp(name,"cbr") == 0) {
		    if ( sh->type() < 5 && sh->type() >=0  ) {
		        sname = srm_names[sh->type()];
		    }
		} 
to:
		if (strcmp(name,"SRM") == 0 || strcmp(name,"cbr") == 0) {
		    if ( sh->type() < 5 && sh->type() >=0  ) {
		        sname = srm_names[sh->type()];
		    }
		} else 
			sname = "null";

The previous problem is, sname is assigned to 0 and sprintf tries to get a
string out of it. 

Let me know if it works.
