3822aecd24 Bluetooth: Merge buf.[ch] functionality into hci_core.[ch]
There's no need to maintain a separate module for this anymore.
Subsequent patches will have further simplifications thanks to this
being now handled in a single c-file.

947f7100c5 Bluetooth: Validate callbacks in bt_auth_cb_register
This adds validation for passed callbacks. Previously registered
callbacks need to be explicitly unregistered by passing NULL.
It is no longer possible to implicitly overwrite callback
structure.

Input Output Capabilities generation is factored out to separate
function. This is in preparation for adding more callbacks.

79696d3b34 Bluetooth: Redesign Bluetooth init API
We need to be able to perform the init procedure asynchronously
through a callback. The RX fiber is a good candidate to use for the
callback since it's not active in its normal operation before
drv->open has been called. In order to prepare for a future
bt_disable() API the init API is renamed from bt_init() to
bt_enable(). If a NULL pointer is given as the callback the API
behaves synchronously like the old bt_init().

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.

This patch adds a basic HCI driver registration API along with a fiber
to process data from the driver. A FIFO is used for receiving data

the HCI transport for operation there's an open() callback passed to
the HCI core. This function will be called as soon as an application
initializes Bluetooth functionality through bt_init().

64b117a9b1 Bluetooth: Add support for HCI data buffers
In order to manage incoming and outgoing HCI data (events, commands &
ACL data packets) we need to have some way of storing this into
buffers. This patch implements a 'pool' of buffers with the help of
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.
