Fixes two bugs:
* When a notify is executed before any observers are added, the age is
incremented from 0 to 1. When an observer is registered, the age is not 0
as expected, causing the age to be 1 instead of the expected 2
* The check if a message is newer than the last received one is described
in RFC7641, section 3.4. Simply incrementing age will not comply to what
the RFC describes once the value wraps around. This is now fixed

This commit deprecates these legacy netmask get/set routines
net_if_ipv4_set_netmask()
net_if_ipv4_set_netmask_by_index()
net_if_ipv4_get_netmask()
as they do not work well if there are multiple IPv4 address
assigned to the network interface.
User should use these functions instead
net_if_ipv4_set_netmask_by_addr()
net_if_ipv4_set_netmask_by_addr_by_index()
net_if_ipv4_get_netmask_by_addr()

The netmask should be tied to the IPv4 address instead of being
global for the network interface.
If there is only one IPv4 address specified to the network interface,
nothing changes from user point of view. But if there are more than
one IPv4 address / network interface, the netmask must be specified
to each address separately.
This means that net_if_ipv4_get_netmask() and net_if_ipv4_set_netmask()
functions should not be used as they only work reliably if there is
only one IPv4 address in the network interface.
The new net_if_ipv4_get_netmask_by_addr() and
net_if_ipv4_set_netmask_by_addr() functions should be used as they make
sure that the netmask is tied to correct IPv4 address in the network
interface.

In case conflict is detected (either due to receiving Decline message or

blocked for further use.
Although the RFC is not specific about how long should the address be
blocked, it make sense to implement some fallback mechanisms to reuse
blocked addresses in the server, otherwise, after longer period of
operation, it may run out of usable address.
This commit adds a timeout for declined addresses, so that by default
the address is marked back as "free" after 24 hrs (default lease time).
It also implements a mechanism, which allows to re-use the oldest
declined entry in case the server runs out of fresh addresses to assign.

* The core issue was udp_server_running flag not being cleared when

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.

This commit introduces a new IPv6 API for positive reachability
confirmation, as specified in RFC 4861, Section 7.3.1. This feature aims
to enhance the effectiveness of the Neighbor Discovery mechanism, by
enabling upper-layer protocols to signal that the connection makes a
"forward progress".
The implementation within TCP serves as a reference. Compliance with
RFC 4861, especially Appendix E.1, was ensured by focusing on reliable
handshake and acknowledgment of new data transmissions.
Though initially integrated with TCP, the API is designed for broader
applicability. For example, it might be used by some UDP-based protocols
that can indicate two-way communication progress.

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

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
session close upon receiving CLOSE alert, consecutive non-blocking
recv() calls would report EAGAIN instead of connection closed, if called
before underlying TCP connection was closed.
Fix this, by storing the information that TLS session has ended at TLS
socket level. The new flag will be checked before attempting further
mbed TLS actions, so that connection status is reported correctly.

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.
