First step in Bluetooth protocol stack support.

The code is adopted from the FreeBSD netgraph-based Bluetooth
implementation by Maksim Yevmenkin <m_evmenkin@yahoo.com> but
all netgraph glue was replaced with usual BSD network stack
hooks. This is a work in progress. Only HCI layer works for now,
L2CAP and RFCOMM are on the way.

Help in testing from many, ok markus@.
