luajit: per flow vars and ints
Support for lua global vars so that a luajit script could store data in memory to be used in future executions of the script.

At the vary least we need the ability to use flowints for storing/reading offsets, advertised file length etc. This is important dealing with file formats such as flash so that we know how far into the advertised size we have parsed at stream cutoff.
