Tons of ematch work

 - Fixes a bunch of bugs related to ematches
 - Adds support for the nbyte ematch
 - Adds a bison/flex parser for ematch expressions, expressions
   may look like this:
      ip.length > 256 && pattern(ip6.src = 3ffe::/16)
   documenation on syntax follows
 - adds ematch support to the basic classifier (--ematch EXPR)
