In case zperf session was aborted by the user (by for instance stopping
it from shell), or practically in case of any other
communication-related error, the zperf session could end up in a state
other than NULL or COMPLETED, with no way to recover. This made the
session no longer usable and eventually could lead to zperf being not
able to start a new session anymore.
Fix this by introducing zperf_session_reset() function, which resets the
session state back to defaults. The function is called when the zperf
receiver service is stopped.

This commit fixes restarting of UDP receiver service, along with some
other minor cleanups:
* The core issue was udp_server_running flag not being cleared when
service was stopped. Fix this by introducing udp_receiver_cleanup()
which does all of the required cleanups when receiver service is
stopped. The function is called either when the application stopped
the service with zperf_udp_download_stop(), or when the service was
stopped due to error.
* net_socket_service_unregister() was not called on
zperf_udp_download_stop(), but only from the service callback - that
would not work in case there's no active communication.
* at the same time, net_socket_service_unregister() would be called from
the service callback in case of errors. Fix this, by making
udp_recv_data() only return an error, and let the service callback to
do the cleanup.
* Remove no longer used udp_server_run semaphore
* Remove udp_server_stop - with socket services it seems no longer
needed.
* zperf_udp_receiver_init() now returns an error, so that we don't
mark the service as running in case of socket/services error.

When ENABLED flag is used, we generate 32 byte DTLS

When SUPPORTED flag is used, we just include

Add macro that allows registration of initialization functions that
are called when LwM2M engine starts.
On LwM2M engine starts up, it first executes all initialization
functions in following priority order:
1. LWM2M_PRIO_ENGINE
2. LWM2M_PRIO_CORE, this is where all LwM2M core objects are initialized
3. LWM2M_PRIO_OBJ, this is where all other objects are initialized
4. LwM2M_PRIO_APP, application initialization.
Now on the initialization phase, we could rely that certain objects have
already been registered.
For example custom objects can register callbacks to core objects.
On application phase, we can initialize sensor objects and register
their callbacks because objects have already been initialized.
This LWM2M_ON_INIT() should replace all use of SYS_INIT()
with the default CONFIG_KERNEL_INIT_PRIORITY_DEFAULT.
Priority order is actually just alphabetical order of names, so
the order is set on a linkin phase, and we don't need any
runtime checking for it.

In case TLS session is closed at the TLS level (and thus recv() reports
0 to the application) a certain race occurs between consecutive recv()
call, and TCP session teardown. As mbedtls_ssl_read() only reports

recv() calls would report EAGAIN instead of connection closed, if called

There are several subsystems and boards which require a relatively large
system heap (used by k_malloc()) to function properly. This became even
more notable with the recent introduction of the ACPICA library, which
causes ACPI-using boards to require a system heap of up to several
megabytes in size.
Until now, subsystems and boards have tried to solve this by having
Kconfig overlays which modify the default value of HEAP_MEM_POOL_SIZE.
This works ok, except when applications start explicitly setting values
in their prj.conf files:
$ git grep CONFIG_HEAP_MEM_POOL_SIZE= tests samples|wc -l
157
The vast majority of values set by current sample or test applications
is much too small for subsystems like ACPI, which results in the
application not being able to run on such boards.
To solve this situation, we introduce support for subsystems to specify
their own custom system heap size requirement. Subsystems do
this by defining Kconfig options with the prefix HEAP_MEM_POOL_ADD_SIZE_.
The final value of the system heap is the sum of the custom
minimum requirements, or the value existing HEAP_MEM_POOL_SIZE option,
whichever is greater.
We also introduce a new HEAP_MEM_POOL_IGNORE_MIN Kconfig option which
applications can use to force a lower value than what subsystems have
specficied, however this behavior is disabled by default.
Whenever the minimum is greater than the requested value a CMake warning
will be issued in the build output.
This patch ends up modifying several places outside of kernel code,
since the presence of the system heap is no longer detected using a
non-zero CONFIG_HEAP_MEM_POOL_SIZE value, rather it's now detected using
a new K_HEAP_MEM_POOL_SIZE value that's evaluated at build.

When a TCP connection is established, if there is no data exchange

In CoAP blockwise the client is supposed to
respond with 2.31 Continue code on Ack. This was recently
broken when Block1 parsing was moved after the initialization
of reponse packet. We need separate CoAP API to modify the code
of existing CoAP packet.
Also Ack packet should contain the Block1 options, even the
last one.

Implement testcases for Information Reporting Interface [300-399]:
* LightweightM2M-1.1-int-301 - Observation and Notification of parameter
values
* LightweightM2M-1.1-int-302 - Cancel Observations using Reset
* LightweightM2M-1.1-int-304 - Observe-Composite Operation
* LightweightM2M-1.1-int-306 – Send Operation
* LightweightM2M-1.1-int-307 – Muting Send
* LightweightM2M-1.1-int-308 - Observe-Composite and Creating
Object Instance
* LightweightM2M-1.1-int-309 - Observe-Composite and Deleting
Object Instance
* LightweightM2M-1.1-int-310 - Observe-Composite and modification of
parameter values
* LightweightM2M-1.1-int-311 - Send command
303 and 305 cannot be implemented using Leshan as it only support
passive cancelling of observation.

If the interface is WiFi one, then print information about it.
Also the device information is useful to know so print device
name corresponding to the network interface.

Move the syscall_handler.h header, used internally only to a dedicated
internal folder that should not be used outside of Zephyr.

Do not include the resource type (rt=) in the registration message when
using the OMA JSON format. This was a workaround specifically for the
Wakaama LwM2M server which is no longer needed since the latest master
branch.

Portfolio object created string buffers for Identity resources
that was overlapping on some cases.
Don't calculate pointers by hand, allow compiler to calculate it.

creation of resource instances as well.
Similarly, add support for deleting.

If user adds IPv6 address to the network interface, check
if the address is a multicast one and add it to multicast
group if it is.

Default behaviour should only bind to port independent of IP, this
allows even multicast/broadcast L4 traffic to be received.
User can always specify a specific address to bind using shell or
Kconfig or API.
