Make the memory limit (in bytes or packets) used for storing packets
configurable via command line options and print specific drop numbers
at the end. This allows to tune the buffering when using multiple
threads.
This also fixes a logic arrow in enforcing the limits.
The patch for the enhanced counters is from Anders Broman.
