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.

This driver acts as a pass-through, taking raw HCI data, converting
it to SPI comms and vice versa. It works in the same way as the
existing H:4 and H:5 drivers, only it uses SPI instead of UART.
In this first release, the only BLE board which has been tested is
the X-NUCLEO-IDB05A1:
http://www.st.com/en/ecosystems/x-nucleo-idb05a1.html
Although the current supported SPI format works like the one below,
it should be trivial to adapt it to support other chips with a
different format.
SANITY CHECK = 0x02
SPI WRITE = 0x0A
SPI READ = 0x0B
Tx Format:
[HOST] {SPI WRITE} 0x00 0x00 0x00 0x00 {HCI MESSAGE ...}
[CHIP] {SANITY CHECK} {FLASH SIZE} 0x00 0x00 0x00 {0xFF * MESSAGE LEN}
Rx Format:
{IRQ LINE GOES HIGH}
[HOST] {SPI READ} 0x00 0x00 0x00 0x00 {0xFF * BYTES TO READ}
[CHIP] 0x02 {FLASH SIZE} 0x00 {BYTES TO READ} 0x00 {HCI MESSAGE ...}

The new IS_ENABLED macro allows exposing conditionally enabled code
always to the compiler, even though it may not ultimately end up being
built. This is in particular useful for letting the compiler catch any
logging format string errors. Introduce a new BT_DBG_ENABLED macro
that c-files need to define before including <bluetooth/log.h> in
order to choose whether BT_DBG() logs are enabled or not.
When no Bluetooth logs are enabled the patch also modifies the log
macros to have the format strings checked with the help of the
__printf_like annotation and empty static inline functions.

Since callers of bt_recv() have so far anyway been required to know in

So far the use of k_sem meant that there was no major benefit of
having more than 2 or 3 RX buffers since there was no queuing
mechanism. Instead of using k_sem, introduce a k_fifo and use that to
queue up incoming buffers. This way the RX buffer count can be
increased with measurable effects on throughput.

In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information
in the pool, and removing any 'const' members from net_buf. Since
there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".
This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:
NET_BUF_POOL_DEFINE(pool_name, ...);
Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.
This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

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.

Making a reference to the common work queue code should not necessarily
drag in the system workqueue, since it is possible to use a workqueue
that is not the system workqueue. This is done by moving the system
workqueue into its own code module.
Moving the system workqueue to its own code module allows removing the
NANO_WORKQUEUE and SYSTEM_WORKQUEUE kconfig options, and compiling the
common workqueue code and system workqueue all the time. They are only
linked in the final image if a reference to them exist, same as the
other kernel modules.

In 3 of our UART driver implementations the ISR is exclusively
used and enabled for the RX path. The existing logic was
susceptible to a stall situation where a polled out transmission
would be interrupted by a reception and then the ISR code
would loop forever due to the TX event being signalled (although
the interrupt itself was disabled) causing the ISR to keep
looping for an RX interrupt.

The bt_driver API was created when Zephyr only had a Bluetooth host

this, move all HCI drivers to drivers/bluetooth/hci/ and rename the
