gprs_ns2: introduce NS dialects
A NS dialect describes how the NS Entity interacts with
different virtual circuits. E.g. ipaccess use reset/block on udp
and is a dynamic connection.
A single NS Entity can only support one dialect. This can be later
used to protect a NS Entity against dynamic NS virtual circuits of a
different type.
It further allows a bind to support multiple dialects at the same time.
