This replace the old code that could only compare 16 bits UUID with
bt_uuid_cmp which can expand to 128 bits if types don't match.

Now that we have the connected/disconnected callbacks available for
L2CAP channels we can use these to associate the bt_conn with a
respective protocol-specific context.

We'll either way need various callbacks as well as get rid of the
channel-specific contexts in conn.h, so add a dynamic way of
registering fixed channels. The LE signaling channel is handled in the
same way as any other channel.

Encoding the L2CAP header when allocating the buffer means that we
must know the final size up-front. This is not always possible, so
move the header encoding to bt_l2cap_send() and only have the
bt_l2cap_create_pdu() function reserve enough headroom without
actually encoding anything.
