Create an unattached filter
Usage

Arguments
pfp
the unattached filter that is created
fprog

Overview
Create a filter independent of any socket. We first run some sanity checks on it to make sure it does not explode on us later. If an error occurs or there is insufficient memory for the filter a negative errno code is returned. On success the return is zero.
