e979d656cc bluetooth: controller: Split events into normal and priority
For the host to be able to block on the recv_thread while waiting for a
number of completed packets HCI event, those are pulled from the radio
in a new, higher priority thread that also schedules the execution of
the lower priority event/ACL data recv_thread.

88b620550c Bluetooth: Controller: Switch to controller-side RX thread
Since the controller already uses a thread for receiving data it makes
sense to enable the BLUETOOTH_RECV_IS_RX_THREAD option.

85cfff0d92 Bluetooth: Controller: Kconfig fast encryption setup feature
Enable connection encryption setup in 3 connection
intervals. Peripheral will respond to Encryption Request
with Encryption Response in the same connection interval,
and also, will respond with Start Encryption Response PDU in
the 3rd connection interval, hence completing encryption
setup in 3 connection intervals. Encrypted data would be
transmitted as fast as in 3rd connection interval from the
connection establishment. Maximum CPU time in Radio ISR will
increase if this feature is selected.

404e7662e0 Bluetooth: Controller: Kconfig Tx buffer size
Add Kconfig configuration to select Tx buffer size, this
value will be returned in the HCI LE Read Buffer Size
command response.
This configuration will allow lower Tx RAM usage when
larger PDU sizes are desired in Rx direction only.

This will save CPU time, flash and RAM, if this feature is

4b7cdd499f bluetooth: Tune stack sizes after measuring with hci_uart
The following readings were obtained after running the peripheral and
central_hr apps in qemu combined with the controller (hci_uart) on nRF51
and nRF52:

Main Stack 380
Idle Stack: 68
ISR stack: 532
Controller RX Stack: 388
HCI TX Stack: 516

The numbers set in this change provide a safety margin from the ones
measured empirically.

7.5ms

c583a9f43b Bluetooth: Kconfig: Restructure for a more logical hierarchy
Restructure the Bluetooth options more logically.

- Both host and controller are now behind the same high level
  CONFIG_BLUETOOTH.

- Selecting controller support disables other HCI driver selection, so
  the controller isn't in the same list as HCI drivers any more.

- Under the top-level there's a "Custom stack" option, which when
  enabled opens up the option of choosing CONFIG_NBLE.

There are various other cleanups and simplifications in this patch as
well, since splitting these up would have been fairly tricky while
making sure all test cases still build.

f7d313b154 Bluetooth: Controller: Add ASSERT info dump on HCI builds
When building Zephyr in the controller-only configuration,
assertions that happen in the Link Layer code are not visible
to the Host which is running on another HCI and connected via
UART or USB to it. This patch allows the Controller code
to output the assertion line number when in such a configuration,
allowing the Host to view the event to help debugging.

The event format used is temporary and will be replaced by a
standardized Vendor Specific specification to come at a later
time.
