79b044b61b logging: move _is_user_context() check down one level
MISRA-C Directive 4.7 says that error information returned from
a function needs to be tested. In the logging macros,
return from _is_user_context() is not needed until logging is
enabled and above minimal logging level. There is a potential
that the return is not being used at all. So move it one level
below as it is surely being used within the if block.

cae8bd7408 sys: util: cast input of KB() to size_t for large number
Numbers in C macros are treated as signed integer. This causes
issues when using macro KB(x). If the result is larger than
(2^31 - 1), it is treated as a negative number downstream.
For example, the RAM size of up_squared is 2GB. The result of
KB(CONFIG_SRAM_SIZE) should be 2147483648, but due to being
casted as signed, the result is instead -2147483648. Any
calculations using this would be incorrectly. Fix it by
casting x in KB(x) to size_t first.

b9caaf217e net: lwm2m: Fix Security and Server object instance matching
A proper way to match a Security object instance with a Server object
instance is via Short Server ID resource. Both coupled object instances
should carry the same value of this resource in order to me considered
matched.

This was not implemented in the LwM2M library and it was incorrectly
assumed that the Security object instance index corresponds to the
Server object instance index. While such apporach works is simple
scenario, it might yield incorrect results when bootstrap is used.

Fix this, by verifyng the Short Server ID resource in the Secuirty
instance used, and finding a matching Server instance. The server object
instance is stored for future use in the engine.

Additionally, remove an extra Server object instance that was created
when the bootstrap procedure was used. Since the boostrap Security
object instance does not have the corresponding Server object, it's
enough to have a single Server instance.

884d6e6941 devicetree: gpio: make flags default to 0
The vast majority of devicetree bindings for GPIO controllers are
expected to have "flags" cells in their respective GPIO specifiers,
but that's not required by the specification and we want to make sure
to support that.

However, so many drivers and applications initialize gpio_dt_flags_t
values that it's silly to require each and every one of them to check
for the flags value and fall back to the sensible default flags value
of 0 when it does not exist.

Make the API easier to use correctly by returning 0 in the devicetree
core API for accessing flags, whenever there are no flags defined.

8ce260d8df kernel: introduce supervisor-only stacks
These stacks are appropriate for threads that run purely in
supervisor mode, and also as stacks for interrupt and exception
handling.

Two new arch defines are introduced:

- ARCH_KERNEL_STACK_GUARD_SIZE
- ARCH_KERNEL_STACK_OBJ_ALIGN

New public declaration macros:

- K_KERNEL_STACK_RESERVED
- K_KERNEL_STACK_EXTERN
- K_KERNEL_STACK_DEFINE
- K_KERNEL_STACK_ARRAY_DEFINE
- K_KERNEL_STACK_MEMBER
- K_KERNEL_STACK_SIZEOF

If user mode is not enabled, K_KERNEL_STACK_* and K_THREAD_STACK_*
are equivalent.

Separately generated privilege elevation stacks are now declared
like kernel stacks, removing the need for K_PRIVILEGE_STACK_ALIGN.

b0c155f3ca kernel: overhaul stack specification
The core kernel computes the initial stack pointer
for a thread, properly aligning it and subtracting out
any random offsets or thread-local storage areas.
arch_new_thread() no longer needs to make any calculations,
an initial stack frame may be placed at the bounds of
the new 'stack_ptr' parameter passed in. This parameter
replaces 'stack_size'.

thread->stack_info is now set before arch_new_thread()
is invoked, z_new_thread_init() has been removed.
The values populated may need to be adjusted on arches
which carve-out MPU guard space from the actual stack
buffer.

thread->stack_info now has a new member 'delta' which
indicates any offset applied for TLS or random offset.
It's used so the calculations don't need to be repeated
if the thread later drops to user mode.

CONFIG_INIT_STACKS logic is now performed inside
z_setup_new_thread(), before arch_new_thread() is called.

thread->stack_info is now defined as the canonical
user-accessible area within the stack object, including
random offsets and TLS. It will never include any
carved-out memory for MPU guards and must be updated at
runtime if guards are removed.

Available stack space is now optimized. Some arches may
need to significantly round up the buffer size to account
for page-level granularity or MPU power-of-two requirements.
This space is now accounted for and used by virtue of
the Z_THREAD_STACK_SIZE_ADJUST() call in z_setup_new_thread.

5326d11e8c net: l2: ppp: add generalized "my options" negotiation
So far there was no generalized way how to handle negotiation of "my
options" (those sent with Conf-Req packet to peer). Peer response for
proposed options and their values were not tracked in any way, so
rejected (by peer) options were sent over and over again in subsequent
Conf-Req packets. In case of IPCP it means that all sent options such as
IP_ADDRESS, DNS1, DNS2 were mandatory for being supported by peer in
order to successfully finish negotiation. For example if 'pppd' was the
configured peer (e.g. when using with QEMU and net-tools scripts),
without ms-dns being configured (which is the default), then "my
options" negotiation failed.

Introduce generalized mechanism for negotiating "my options", so it is
easier to maintain current set of supported options and easily add new
options to the implementation in future. FSM instance inititialization
function can provide information about supported "my options".
Information is is passed as a table of 'struct ppp_my_option_info'
containing:

 * option code (type),
 * callback for adding option to Conf-Req packet,
 * callback for received Conf-Ack with that option,
 * callback for received Conf-Nak with that option.

Store also runtime information about each negotiated option. First of
all remember which options have been rejected, so they are not sent to
peer once again in the next Conf-Req packet. This will solve issue with
IPCP negotiation when peer doesn't support DNS1 or DNS2 options. Keep
also track about which options have been acked, so such information can
be verified before bringing FSM instance up.

Make also an improvement in generic FSM code and reply with
Configure-Rej to all Configure-Req for which there is no config_info_req
callback set. Use that to drop LCP specific Conf-Req handling code,
because there is no option properly supported there yet.
