so long term, we need to keep socket states inside l2cap_sock.c and
L2CAP states inside l2cap_core.c. Since L2CAP core engine should use the
states from the specification and not try to fit into socket states.
I see a little bit of value here in having them in the debug log, but
making them public like this seems a big overhead. Did you measure the
size difference. And most likely some state lookup table is better.

Marcel
