luajit: add flowint support

Expose ScFlowintGet and ScFlowintSet functions to luajit. These set
flowints in real time, regardless of rule and/or script match.

Example:

function init (args)
    local needs = {}
    needs["http.request_headers"] = tostring(true)
    needs["flowint"] = {"cnt"}
    return needs
end

function match(args)
    a = ScFlowintGet(0);
    if a then
        ScFlowintSet(0, a + 1)
    else
        ScFlowintSet(0, 1)
    end

    a = ScFlowintGet(0);
    if a == 23 then
        return 1
    end

    return 0
end

return 0

Script's init call first registers "cnt" at id 0, then 0 is used to use
this var.
