python: Add flow filtering syntax.
Based on pyparsing, create a very simple filtering syntax.
It supports basic logic statements (and, &, or, ||, not, !), numerical
operations (<, >), equality (=, !=), and masking (~=). The latter is only
supported in certain fields (IntMask, EthMask, IPMask).
Masking operation is semantically equivalent to "includes",
therefore:
ip_src ~= 192.168.1.1
means that ip_src field is either a host IP address equal to 192.168.1.1
or an IPMask that includes it (e.g: 192.168.1.1/24).
