scamper:
* fix memory leak when receiving TCP responses in tracelb.
* do not use the global address cache in tracelb: use a local one.
* in qsort with 3-way partition, do not compare items against
  themselves.
* improve performance of warts_addr_t code
* use calloc instead of malloc() -> memset(0) on systems where calloc
  is available.
* do not use the global address cache in ping: most responses are
  either from the destination, or from the same IP address, so
  optimize for that.

The last three performance improvements were prompted by Alistair King
at CAIDA.
