We use addresses in lots of places and with LE we always need to pass
around the type in addition to the address value. Defining dedicated
types for addresses makes the code much simpler.

Now that there's the split of Command Complete/Status events from all
other RX data we don't anymore need dedicated per-connection RX
fibers. Remove these fibers and their associated FIFO and use
bt_l2cap_recv() directly from bt_conn_recv().

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.

If we have a buffer that's larger than the supported ACL MTU we need
to split it into multiple fragments. The first fragment will have
'start' in the flags that are encoded to the connection handle and
subsequent ones will have 'continue' encoded into them.
To not loose track of the original buffer until we have created all of
the fragments we store each buffers in a temporary FIFO and then later
read them back out from there and put them into the tx_queue.

There's no point in encoding the ACL header in bt_conn_create_pdu()
since ultimately we might end up having to split the data into
multiple buffers - each with their own ACL header. Instead, move the
header encoding into bt_conn_send() where we can later add the proper
fragmentation support.

We're already sending 'dummy' buffers to wake up the connection
fibers. The problem is that if we provide a real buffer type it may
have unintended consequences. E.g. with BT_ACL_OUT when bt_buf_put()
is called it may trigger an invalid HCI_Host_Num_Completed_Packets
command.
This patch creates a new BT_DUMMY buffer type to avoid this scenario.
The new type is an alias for BT_CMD since the pool where these buffers
come from is not quota-controlled and synced up with the controller.

To ensure that we never have more outgoing ACL buffers available than

calling drv->send() and getting the corresponding Number of Completed

We may soon want to have a _wait() variant of bt_buf_get, so to avoid
the number of 'get' function growing too large consolidate the
existing get() and get_reserve() functions into a single one. The new
consolidated function also takes the type as input parameter so that
we know this from the very start and thereby plan for the split into
multiple buffer pools.

types.

another for outgoing data. For now only one connection is supported.
