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
Merge branch 'master' into examine_allocations

This merge is so this branch can take advantage of travis-ci.
Remove function 'normalize' in MAC address parsing

This function was used for the case that there was only one octet in a
MAC address fragment. Example:

f:f:f:3:3:3

This kind of addresses are not valid MAC addresses but libpcap accepts
them. When there's an address like this, what is missing is the leading
zero, not the trailing zero. The 'normalize' function considered
that the octet missing was the trailing zero, and wrongly shifted the
octet 4 bits.
Operators 'fddi', 'tr' and 'wlan' are aliases of 'ether'
Implement lowering 'proto' and 'protochain'

* 'proto <protocol>' is the same as 'ip proto <protocol>'.
* 'protochain <protocol>' is the same as 'ip protochain <protocol>'.
Add example 'proto sctp'
