pflua-match can now read lua filters from a file
Added a tool to check for unsunk allocations

This tool reports on any unsunk allocations within 'interesting' traces.
It respects PF_VERBOSE, and will dump full traces for any unsunk allocations
if it is set.

Use: ./pflua-allocchecker ./pflua-match wingolog.org.pcap tcp
Debug use: ./pflua-allocchecker -O-cse ./pflua-match wingolog.org.pcap tcp
Declare all pf/*.lua files 'boring' for allocation analysis
