Select CPU_CORTEX_M_HAS_CMSE in ARMV8_M arhitectures.
Option ARMV8_M_BASELINE is introduced for this purpose,
so that CMSE API is enabled for both Cortex-M23 and
Cortex-M33 MCUs.

This commit defines and implements an internal ARMv8-M API
that allows the user to evaluate access permissions of memory
locations, based on the ARMv8-M Test Target (TT) instruction
support.

When the IV Update state enters Normal operation or IV Update in
Progress, we need to keep track of how many hours has passed in the
state, since the specification requires us to remain in the state at
least for 96 hours (Update in Progress has an additional upper limit
of 144 hours).
In order to fulfil the above requirement, even if the node might be
powered off once in a while, we need to store persistently how many
hours the node has been in the state. This doesn't necessarily need to
happen every hour (thanks to the flexible duration range). The exact
cadence will depend a lot on the ways that the node will be used and
what kind of power source it has.
Since there is no single optimal answer, this patch adds a new
configuration option, which allows specifying a divider, i.e. how many
intervals the 96 hour minimum gets split into. After each interval the
duration that the node has been in the current state gets stored to
flash. E.g. the default value of 4 means that the state is saved every
24 hours (96 / 4).

Majority of "accessing Internet" setup is the same for both QEMU and

entire net_app. Finally, add information about DNS setup for the

coap-server(RPL-node) about parent status, client has to register
observer for notifications.

though CoAP messages. Build toplogy matrics and send it to

This patch fixes some bugs found during testing with testusb from
linux kernel.
An unresolved issue is that the stack is not fast enough
to stall (if necessary) the control endpoint during Setup Stage.
This might require a API change so that the usb device stack
can explicit allow the driver to resume token processing.

Similar to what has been done with pipes and message queues,
user mode can't be trusted to provide a buffer for the kernel
to use. Remove k_stack_init() as a syscall and offer
k_stack_alloc_init() which allocates a buffer from the caller's
resource pool.

User mode can't be trusted to provide the kernel buffers for
internal use. The syscall for k_pipe_init() has been removed
in favor of a new API to draw the buffer memory from the

kernel memory.

Dynamic kernel objects no longer is hard-coded to use the kernel
heap. Instead, objects will now be drawn from the calling thread's
resource pool.
Since we now have a reference counting mechanism, if an object
loses all its references and it was dynamically allocated, it will
be automatically freed.
A parallel dlist is added for efficient iteration over the set of
all dynamic objects, allowing deletion during iteration.

Some kernel APIs may need to allocate memory in order to function
correctly, especially if they are exposed to userspace where
buffers provided by user code cannot be trusted.
Instead of simply drawing from the system heap, specific pools
may instead be assigned to threads, and any requests made on
behalf of the calling thread will draw heap memory from that pool.

An object's set of permissions is now also used as a form
of reference counting. If an object's permission bitmap gets
completely cleared, it is now possible to specify object type
specific cleanup functions to be implicitly called.
Currently no objects are enabled yet. Forthcoming patches
will do this on a per object basis.

Forthcoming patches will dual-purpose an object's permission
bitfield as also reference tracking for kernel objects, used to
handle automatic freeing of resources.
We do not want to allow user thread A to revoke thread B's access
to some object O if B is in the middle of an API call using O.
However we do want to allow threads to revoke their own access to
an object, so introduce a new API and syscall for that.
