Make json_pack/json_unpack() recursive Note that we pass va_list pointers around instead of just va_lists, which would seem more intuitive. This is necessary since the behaviour of va_lists passed as function parameters is finicky. Quoth stdarg(3): If ap is passed to a function that uses va_arg(ap,type) then the value of ap is undefined after the return of that function. The pointer-passing strategy is used by Python's Py_BuildValue() for the same purpose.
