Update the advertising API according to what has recently been
discussed and agreed upon.
Naming-wise the most important change is the removal of "EIR" which
was confusing since this is mainly used with LE at the moment. The
Core Specification Supplement consistently uses the generic terms data
and data type to describe what we're dealing with here, so the new
names are bt_data and BT_DATA.
Another change is to detach the actual data from the struct by
converting it from an array to a pointer. This is not only essential
for supporting BR/EDR (which has a different length) but to also
minimize memory usage.
Another change is to require the caller of bt_le_adv_start() to
provide the array lengths of the ad and sd paramters. This way we
don't have to have the empty (8-byte) element at the end of each
array.
Lastly, the bt_le_adv_start() logic is slightly modified so that it
will always clear the respective data if necessary. Previously the
user might have been left with a previous callers data if it passed
NULL to the API.

Once we start persistently storing the addresses of devices we want to
reconnect to we also need a way to reload them to the stack. Since we
don't have a connection object at this point the API cannot take that
as a parameter. Instead rename the function and have it take
bt_addr_le_t as a parameter.
The feature was also lacking proper reference counting for the
connection, which this patch now adds (the flag itself owns a
reference). The function is now also possible to call before bt_init()
so that if we load the stack with multiple devices the HCI doesn't get
bombarded with lots of scan enable/disable commands.

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().

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.

Almost all callers of bt_buf_add end up having to do explicit type
casts of the return value since 'uint8_t *' rarely fits what's needed.
Changing the return type to 'void *' removes this extra type casting
need and makes the API friendlier to its users.

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.

In certain scenarios we want to keep the buffers around for longer
and avoid the default bt_buf_put() calls from putting them back to the
available buffers queue. This patch adds reference counting for the
buffers, along with a bt_buf_hold() API to increment the reference
count. Now bt_buf_put() will only put the buffer back to the pool if
the reference count hits 0.

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.

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.

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).

we know this from the very start and thereby plan for the split into

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
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.
