This offesr memory allocation with a packet scope making memory leaks less likely and memory management faster.
Add initialization calls for both tethereal and ethereal.
Convert the ip_to_str() function to use this and avoid doing the silly rotating buffers thing it previously did.
We also need an equivalent set of functions for allocation with capture file scope (free when next capture is loaded) but i dont know where to put the free_all call.
