Token and payload are appended from data buffers to a CoAP packet

appending these parts to a packet.
Now token and paylod can be copied to CoAP packet from constant
buffers, that can be stored in ROM.

In the current interrupt nesting implementation, if an ISR is
interrupted while executing inside a branch, the lr_svc register will
be corrupted, and the branch of the interrupted ISR will exit to the
return address of the final branch of the interrupting ISR, which may
or may not correspond to the intended return address.
This commit fixes the aforementioned bug by storing the lr_svc register
in the stack at the ISR entry, and restoring its value before exiting
the ISR.

The DF tests are implemented to be executed with nrf52_bsim platform.
The nrf52_bsim platform does not include Direction Finding Extenstion.
Due to that, radio_df.c compilation failed with error about missing
antenna configuration in DTS.
To solve the problem, I've changed nrf.cmake to include radio_df.c
file when CONFIG_BT_CTLR_DF is defined and CONFIG_SOC_SERIES_BSIM_NRFXX
is not definded.
Thanks to that any other platform is not affected. The file will not
build if there is no appropriate configuration or there are missing
features in a hardwared.
Unit tests have provided stub imlpementation or radio functionality.
If nrf52_bsim has implemented Direction Finding Extension, the
DF unit tests code will stil work and will not require additional
changes. Also content of the file is not affected by contional
compilation entries.

Remove ATT modifying the L2CAP channel state by unassigning the
the connection pointer on timeout.
Unassigning this pointer does not prevent the ATT channel from receiving
since bt_l2cap_recv does not inspect this pointer before calling the
channel receive function.
This prevented the disconnected callback from being called on the
channel after the channel had timed out, but since the disconnected
callback now handles this case this workaroun is no longer needed.

Handle ATT timeout on disconnected ATT channel.
When the ATT channel is disconnected with a pending request the ATT
timeout is canceled and the response processed with an error code.
However canceling of delayed work is not guaranted to succeed, e.g:
"Work queue thread has removed the work item from the queue but has not
called its handler"
This could lead to timeout handler being invoked after the disconnected
handler.

While using the encoded path to a device tree node guarantees a unique
identifier for the corresponding device there is a limit on the number
of characters of that name that can be captured when looking up a
device by name from user mode, and the path can exceed that limit.
Synthesize a unique name from the node dependency ordinal instead, and
update the gen_defines script to record the name associated with the
full path in the extern declaration.
Add a build-time check that no device is created with a name that
violates the user mode requirement.
Also update the network device DTS helper functions to use the same
inference for dev_name and label that the real one does, since they
bypass the real one.

So far device_pm_state_str() was built only when CONFIG_PM=y (former
CONFIG_SYSTEM_POWER_MANAGEMENT=y). 'device list' shell
command (CONFIG_DEVICE_SHELL=y) is using that function when
CONFIG_PM_DEVICE=y. This resulted in build failures when CONFIG_PM=n, as
linker could not find its implementation.
Build device_pm_state_str() function regardless of CONFIG_PM value, so
device shell module builds successfully in every case.

Calculate crc32 4 bits at a time. The return value of the calculation is
identical to the previous 1 bit at a time implementation.
Results in a speed up of a factor 3 at the cost of using 64 bytes of
flash for a crc table.
Calculating crc32 of 128kB of flash on a 120MHz Kinetis MKE16F512
Cortex-M4 takes 99ms using the 1 bit at a time implementation, and 30ms
using the 4 bits at a time implementation.
The crc32 routine is used by subsys/canbus/canopen/canopen_program.c to
calculate crc of flash images.

With classic volatile pointer access gcc something generates
access instructions with immediate offset value, like
str w4, [x1], #4
Such instructions produce invalid syndrome in HSR register when are
trapped by hypervisor. This leads to inability to emulate device access
in hypervisor.
So we need to make sure that any access to device memory is done
with plain str/ldr instructions without offset.

At its current state, the script tries to access the vector table
list without checking first that the index is valid. This can
cause the script to crash without a descriptive message.
The index can be invalid if an IRQ number that is larger than
the maximum number allowed by the SOC is used.
This PR adds a check of that index, that exits with an error
message if the index is invalid.

Adds tests checking that we can use memory allocated by malloc(),
calloc() and realloc() to access objects of some common types,
including uint64_t and double.
It works by doing a number of allocations of various sizes and
dereferencing the returned pointer. The purpose is to catch cases where
the application would trap if accessing the allocated memory. (The
test does not check alignment against the ABI or alignof().)

"Designed for safe allocation of arrays, the reallocarray()

calculation nmemb * size."
