Attempt to fix C++ error: taking address of temporary array.
According to GCC documentation:
In C++, a compound literal designates a temporary object that only
lives until the end of its full-expression.
Finishing with this recommendation:
As an optimization, G++ sometimes gives array compound literals
longer lifetimes: when the array either appears outside a function
or has a const-qualified type.
But it is probably safest just to avoid the use of array compound
literals in C++ code.
Fix the issue by introducing INIT macros as an alternative, and use
these in the inline functions to avoid the use of array compound
literals in Bluetooth headers.

This implements a file descriptor used for event notification that
behaves like the eventfd in Linux.
The eventfd supports nonblocking operation by setting the EFD_NONBLOCK
flag and semaphore operation by settings the EFD_SEMAPHORE flag.
The major use case for this is when using poll() and the sockets that
you poll are dynamic. When a new socket needs to be added to the poll,
there must be some way to wake the thread and update the pollfds before
calling poll again. One way to solve it is to have a timeout set in the
poll call and only update the pollfds during a timeout but that is not
a very nice solution. By instead including an eventfd in the pollfds,
it is possible to wake the polling thread by simply writing to the
eventfd.

So far, coap_pending structure kept track only of the timeout interval
between two consecutive retransmissions. Calculations inside
`coap_pending_next_to_expire` relied only on this value. This approach
gives incorrect results though, in case multiple messages are pending
for retransmission.
For instance, assuming initial retransmission timeout is set to 2
seconds. If some message had been retransmitted already, its timeout
would be increased to 4 seconds. Any new message added to the pending
list would have a retransmission timeout set to 2 seconds, and will be
returned as a first message to expire, no matter how long the initial
message was already on the list.
To resolve this, add a `t0` field to the coap_pending structure. This
field is initialized to the initial transmission time, and is increased
on each retransmission by the retransmission timeout.
`coap_pending_next_to_expire` uses this value to calculate absolute
time, when the next retransmission should take place, and based on this
information returns correctly first pending message to expire.

This default-y option allows continued use of the legacy devicetree
macros.
There are no functional changes yet, but when this is default n,
old-style DT code won't build. At that point, adding any of these will
be a fix to keep old-style code working:
- "CONFIG_LEGACY_DEVICETREE_MACROS=y" to prj.conf
- "-- -DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the west build command
- "-DCONFIG_LEGACY_DEVICETREE_MACROS=y" to the cmake command
This option can be changed to default n in time for the Zephyr 2.3
release. That will provide users of Zephyr 2.2 with a smooth migration
path to the new devicetree.h API after 2.3 is released, which
nonetheless will alert them immediately that something is wrong due to
build errors.
Unfortunately, __DEPRECATED_MACRO is not sufficient in all cases as a
warning to users. This is because, at least in GCC, macros defined
using __DEPRECATED_MACRO cannot be used in preprocessor lines like

The previous architecture proved unable to support user expectations,
so the API has been rebuilt from first principles. Backward
compatibility cannot be maintained for this change.
Key changes include:
* Formerly the service-provided transition functions were allowed to
sleep, and the manager took care to not invoke them from ISR
context, instead returning an error if unable to initiate a
transition. In the new architecture transition functions are
required to work regardless of calling context: it is the service's
responsibility to guarantee the transition will proceed even if it
needs to be transferred to a thread. This eliminates state machine
complexities related to calling context.
* Constants identifying the visible state of the manager are exposed
to clients through both notification callbacks and a new monitor API
that allows clients to be notified of all state changes.
* Formerly the release operation was async, and would be delayed for the
last release to ensure a client would exist to be notified of any
failures. It is now synchronous.
* Formerly the cancel operation would fail on the last client associated
with a transition. The cancel operation is now synchronous.
* A helper function is provided to safely synchronously release a
request regardless of whether it has completed or is in progress,
satisfying the use case underlying #22974.
* The user-data parameter to asynchronous notification callbacks has
been removed as user data can be retrieved from the CONTAINER_OF
the client data.

Bug fix and improved `payload` handling in `http_client_req`.
Changes to `http_client_req` behaviour:
If the user provides `payload_len` it is used to generate the
`Content-Length` header. This is done even if `payload_cb` is used to
provide the actual data. If no `payload_len` is specified then no
`Content-Length` is generated.
If `payload_cb` is provided it is called to send the payload data.
Otherwise `payload` is used as the payload buffer and sent. If
`payload_len` is not zero, it is used as the size of `payload`.
Otherwise `payload` is assumed to be a string and `strlen` is used to
determine its size. This is to maintain current behaviour and not break
existing samples.

The existing mem_pool implementation has been an endless source of
frustration. It's had alignment bugs, it's had racy behavior. It's
never been particularly fast. It's outrageously complicated to
configure statically. And while its fragmentation resistance and
overhead on small blocks is good, it's space efficiencey has always
been very poor due to the four-way buddy scheme.
This patch introduces sys_heap. It's a more or less conventional
segregated fit allocator with power-of-two buckets. It doesn't expose
its level structure to the user at all, simply taking an arbitrarily
aligned pointer to memory. It stores all metadata inside the heap
region. It allocates and frees by simple pointer and not block ID.
Static initialization is trivial, and runtime initialization is only a
few cycles to format and add one block to a list header.
It has excellent space efficiency. Chunks can be split arbitrarily in
8 byte units. Overhead is only four bytes per allocated chunk (eight
bytes for heaps >256kb or on 64 bit systems), plus a log2-sized array
of 2-word bucket headers. No coarse alignment restrictions on blocks,
they can be split and merged (in units of 8 bytes) arbitrarily.
It has good fragmentation resistance. Freed blocks are always
immediately merged with adjacent free blocks. Allocations are
attempted from a sample of the smallest bucket that might fit, falling
back rapidly to the smallest block guaranteed to fit. Split memory
remaining in the chunk is always returned immediately to the heap for
other allocation.
It has excellent performance with firmly bounded runtime. All
operations are constant time (though there is a search of the smallest
bucket that has a compile-time-configurable upper bound, setting this
to extreme values results in an effectively linear search of the
list), objectively fast (about a hundred instructions) and amenable to
locked operation. No more need for fragile lock relaxation trickery.
It also contains an extensive validation and stress test framework,
something that was sorely lacking in the previous implementation.
Note that sys_heap is not a compatible API with sys_mem_pool and
k_mem_pool. Partial wrappers for those (now-) legacy APIs will appear
later and a deprecation strategy needs to be chosen.

HWINFO drivers should be responsible for ensuring that
the data structure is a sequence of bytes. That is not
what the current sam0 and nordic drivers do. The drivers
read the data as u32_t and then memcpy the data to a
buffer. This ensures the data has the endianness of the
underlying MCU, which in this case is Cortex M0 which
is little endian.
This commit fixes the endianness so the data can be
interpreted as a "left to right sequence of bytes".
This commit updates the API doc to provide clarification
of the data structure.
Add to 2.3 release notes.

This change is to allow access to the firmware block context in order to
give the firmware update callback implementation an indication of when
to reset the flash context. Additionally, it allows for a validity check
between the total expected size downloaded and the actual size
downloaded. A simple implementation can check if the block context's
current downloaded blocks is equal to the expected block size in order
to determine if the flash context needs to be reset. This approach
seemed the simplest, and knowing the firmware block context can have
other purposes. This has been tested by accessing the block context
during the update in the block received callback and confirming that the
callback had information regarding the current downloaded bytes.

Due to the use of UTIL_EVAL*() macros, the UTIL_LISTIFY() macro used
by DT_INST_FOREACH(foo) can cause long build errors when there is a
build error in the expansion for "foo". More than a thousand lines of
build error output have been observed for an error in a single line of
faulty C.
To improve the situation, re-work the implementation details so the
errors are a bit shorter and easier to read. The use of COND_CODE_1
still makes the error messages quite long, due to GCC generating notes
for various intermediate expansions (__DEBRACKET,
__GET_ARG_2_DEBRACKET, __COND_CODE, Z_COND_CODE_1, COND_CODE1), but
it's better than the long list of UTIL_EVAL notes.

The original API was misnamed, as the intent was to provide a manager
that decoupled state management from the service that needed to be
turned on or off. Update all the names, shortening them where
appropriate removing unncessary internal components like _service.
Also remove some API that misled developers into believing that onoff
managers are normally expected to be exposed directly to consumers.
While this is a use case, in most situations there are service or
client-specific actions that need to be coupled to transition events.

Even though radio driver can report in its capabilities that it does
support CSMA CA, there's no way in the driver to select how the frame
should be transmitted (with CSMA or without). As layers above radio
driver (Thread, Zigbee) can expect that both TX modes are available, we
need to extend the API to allow either of these modes.
This commits extends the API `tx` function with an extra parameter,
`ieee802154_tx_mode`, which informs the driver how the packet should be
transmitted. Currently, the following modes are specified:
* direct (regular tx, no cca, just how it worked so far),
* CCA before transmission,
* CSMA CA before transmission,
* delayed TX,
* delayed TX with CCA
Assume that radios that reported CSMA CA capability transmit in CSMA CA
mode by default, all others will support direct mode.
