9b40ec3360 Bluetooth: Introduce dedicated Bluetooth address types

around the type in addition to the address value. Defining dedicated

6e20c3b838 Bluetooth: Move all logs behind CONFIG_BLUETOOTH_DEBUG
The BLUETOOTH_DEBUG config option bumps the stack sizes to cope with
printf requirements. Since all the logs use printf now they should
only be available with the bigger stack sizes to avoid surprises.
There are still basically two levels of log enabling where
BLUETOOTH_DEBUG enables the ERR/WARN/INFO everywhere and the
BLUETOOTH_DEBUG_* enables BT_DBG for a specific subset of the stack.

fbe3a4634d Bluetooth: Add return parameter support to bt_hci_cmd_send_sync()
Instead of having global command completion handler we can keep the
code more concise by letting bt_hci_cmd_send_sync() give back the
return parameters straight to the caller. This patch extends the
buf->hci.sync variable to not just contain the initial semaphore, but
to have the return parameter bt_buf once the semaphore is given back.

The bt_hci_cmd_send_sync() function receives an extra parameter which
may be NULL if the caller isn't interested in the return parameters.

and avoid the default bt_buf_put() calls from putting them back to the

count. Now bt_buf_put() will only put the buffer back to the pool if
the reference count hits 0.

041c84c3e6 Bluetooth: Introduce dummy data type
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.

586d76b12a Bluetooth: Add support for reporting completed ACL buffers
Every time we put a BT_ACL_IN buffer back to the pool we should report
this to the controller so it knows it can send us more data. This
patch makes the necessary modifications to the bt_buf_put() function
to trigger the HCI command.

The Host Number of Completed Packets command is special in that it
doesn't need to obey the reported ncmd value and also doesn't generate
any command status/complete events. Because of this we need an
exception for it in the bt_hci_cmd_send() function.

b6804df02e Bluetooth: Split buffers into separate pools
In order to do proper flow control of ACL data to/from the controller
we need to have precise management of the available buffers. Mixing
with the events/commands buffers would make this impossible. This
patch splits the buffer pools into three separate ones:

	1. HCI commands/events
	2. Incoming ACL data
	3. Outgoing ACL data

The total number of available buffers is also increased to match
what's the smallest number supported by current controllers (to avoid
the stack from becoming a bottle neck).

d210d306d7 Bluetooth: Add full HCI initialization routine
This patch adds a full HCI initialization routine to retrieve all
relevant information from the controller.

We also need to introduce a new blocking bt_hci_cmd_send_sync() API
since some commands are conditional to the results of others. The API
is implemented with the help of a semaphore that's part of the
command's bt_buf struct. We wait on the semaphore and get it back once
the command has completed (with the help of the hci_cmd_done
function).

The patch also adds variables for storing various controller specific
parameters which will be needed later during the operation of the
stack. These variables are part of 'struct bt_dev' and get updated
through the respective command complete handlers.

A new bt_hci_reset() API is added which allows an application to reset
the controller state at any time by re-running the HCI init procedure.

In order to manage incoming and outgoing HCI data (events, commands &
ACL data packets) we need to have some way of storing this into

the nano_fifo API. The pool is initially populated with all available
buffers. After this code can on demand request buffers from the pool
with the help of bt_buf_get() and return buffers back into the pool
with bt_buf_put().

Since we don't always know the execution context from where the API is
operated on, this patch also adds convenience fifo_get/fifo_put
wrappers that look up the exact context before calling the correct
nano_fifo API.

ac63429177 Bluetooth: Add skeleton for HCI core

the configuration options, as well as the very basic header files. The
patch also adds a skeleton for a bt_init() function that applications
will need to call to initialize Bluetooth functionality.
