as making the bt_iso_setup_data_path function a bit more

For non-specified archs, including those out-of-tree, the possibility to
use a specific implementation has been reintroduced.
CONFIG_ATOMIC_OPERATIONS_ARCH must be selected to utilize this.

This adds FPU sharing support with a lazy context switching algorithm.
Every thread is allowed to use FPU/SIMD registers. In fact, the compiler
may insert FPU reg accesses in anycontext to optimize even non-FP code
unless the -mgeneral-regs-only compiler flag is used, but Zephyr
currently doesn't support such a build.
It is therefore possible to do FP access in IRS as well with this patch
although IRQs are then disabled to prevent nested IRQs in such cases.
Because the thread object grows in size, some tests have to be adjusted.

Add the exception depth count to tpidrro_el0 and make it available
through the arch_exception_depth() accessor.
The IN_EL0 flag is now updated unconditionally even if userspace is
not configured. Doing otherwise made the code rather hairy and
I doubt the overhead is measurable.

Add downlink callbacks on a per-port basis. A single message will be
handled as many times as users have registered matching ports. Callbacks
will also be run on "meta" downlink packets on port 0, such as confirmed
uplink acknowledgements.

Move the STM32F0 specific ram vector table sections into a dedicated
linker snippet included by the new `SRAM_VECTOR_TABLE` symbol.
Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au>
Add a new Kconfig symbol that explicitly controls whether the vector
table should be placed in RAM. This eliminates the side effect of
`IS_BOOTLOADER` controlling vector table location. Making the condition
a positive assertion also allows the config to be used in CMakeLists
conditions (`zephyr_linker_sources_ifdef()`, etc).

Since the API already has a function to create an LwM2M object instance,
it makes sense to add a corresponding delete funtion, allowing the
application to delete created objects.
Additionally, for the remote delete set the Registration Update trigger
only when not in bootstrap mode.

So far there was no dedicated mechanism for replacing DNS servers with
new list. Add dns_resolve_reconfigure() API that allows to achieve that
in a thread-safe manner.
Introduce 3rd state in DNS context lifetime by converting from 'bool
is_used' to 'enum dns_resolve_context_state state'. This new
DEACTIVATING state allows to mark a DNS context as busy and safely close
context without holding lock. Closing DNS context with released lock
prevents deadlock in case net_context_close() has to synchronize with a
separate thread executing handler passed to net_context_recv() (which is
the case for example with ESP-AT WiFi driver).

This adds dictionary based logging support. Dictionary based
logging is binary based where one big difference is that
static strings are stored as pointers instead of the whole
string. This results in reduced space requirements for
storing log messages in certain scenairos.

Coverity is complaining about sizeof(v + 0) and it is used
here intentionally to promote variable. Added comment that should
suppress this error in the future.
Note that this macro will be used in all log messages so without
solving it before logging v2 is merged there will be a flood of
errors.

Devices that do not require PM should just use NULL.

Due to the use of gperf to generate hash table for kobjects,
the addresses of these kobjects cannot change during the last
few phases of linking (especially between zephyr_prebuilt.elf
and zephyr.elf). Because of this, the gperf generated data
needs to be placed at the end of memory to avoid pushing symbols
around in memory. This prevents moving these generated blocks
to earlier sections, for example, pinned data section needed
for demand paging. So create placeholders for use in
intermediate linking to reserve space for these generated blocks.
Due to uncertainty on the size of these blocks, more space is
being reserved which could result in wasted space. Though, this
retains the use of hash table for faster lookup.

The return value is documented to be true if the work was pending, but
the implementation returned true only if the work was actually running
(i.e. the caller had to wait). It should also return true if
scheduled or submitted work was cancelled.
Note that this means the return value cannot be used to determine
whether the call slept.

Initializing a work item from its handler will destroy the content of
the kernel structures used to process the work item. This can lead to a
system crash for example when the delayed work is being rescheduled when
the previous run is already queued for processing but not yet executed.
Fix this by initializing the work item once during trickle timer
creation and moving the logic, previously achieved by switching the work
handler, into the new work handler.
