Carles Cufi b77b8e615b Bluetooth: controller: Issue Data Buffer Overflow event
Whenever the HCI ACL flow control is violated by the Host, a Data Buffer
Overflow event is now issued by the Controller (if enabled) to notify
the Host of the buffer overrun.

Carles Cufi 3df18ff277 Bluetooth: controller: Fix Read Version Info VS cmd
Use the macros generated during the build and located in version.h to
fill in the version information in the Read Version Information VS
command. Additionally reply with the correct hardware identifiers when
running on Nordic hardware.

Johan Hedberg 2975ca0754 Bluetooth: Kconfig: Rename CONFIG_BLUETOOTH_* to CONFIG_BT_*
The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.

Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

Carles Cufi a1ff1a0933 Bluetooth: Consolidate flow control Kconfig
Since Controller to Host flow control is a feature that affects both
sides equally, move it to the top-level Kconfig file and consolidate its
use in both Controller and Host.

Carles Cufi 7ebe7da736 Bluetooth: controller: Controller to Host flow control
The Bluetooth Specification allows for optional Controller to Host flow
control based on the same credit-based mechanism as the Host to
Controller one. This is particularly useful in 2-chip solutions where
the Host and the Controller are connected via a physical link (UART, SPI
or similar) where the Host is sometimes required to ask the Controller
to throttle its data traffic while still making sure that relevant
events get through the line.

This implementation is based on a simple queue of pending events and
data that is populated whenever the Controller detects that the Host is
out of buffers and then emptied whenever the Host notifies the
Controller that is ready to receive data again. Events relevant to the
connections are also queued to preserve the order of arrival.

At this point the Controller ignores the connection handle sent by the
Host and treats all connections equally, and it also queues events even
for connections that have no data pending in the queue. Both this items
can be improved if necessity arises.

Note that Number of Completed Packets will still flow freely from the
Controller to the Host regardless of the pending ACL data packets, which
might lead to inconsistencies in the sequential order of certain
operations that include bi-directional data transfer.

Kumar Gala d0eb235510 Bluetooth: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

Johan Hedberg 6c0e9720e2 Bluetooth: Controller: Redesign response buffer allocation for commands
With an upcoming patch the HCI command buffers will be reused for the
Command Complete/Status HCI events. The controller HCI code needs some
refactoring to postpone the event buffer allocation so that the
parsing state of the HCI command buffer isn't touched.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Johan Hedberg 2f191012c2 Bluetooth: Controller: Deprioritize adv report buffer allocation
Advertising reports are the only HCI events which we can drop if we
are low on buffers. Allocate them therefore with K_NO_WAIT rather than
K_FOREVER.
