aaebe38db9 net: Increase net_mgmt task priority
Originally, the net_mgmt task priority is very low. Based on roaming
implementation, roaming is triggered in net_mgmt task. When running UDP
test while doing roaming, the net_mgmt task won't have much chance to
run and roaming can't be triggered.
Increase it to 3, which is same value of supplicant task.

111db23d0a net: mgmt: Fix memory corruption in wait_on_iface
The net_mgmt subsystem offers a function which waits (blocks)
until a specified net event occurs. An event callback is
pushed to the stack, then added to the net_mgmt_event_callback
list. If the event occurs, the net_mgmt thread calls the
callback and deletes the callback from the list. However, if
the event does not occur within the timeout specified when
invoking mgmt_event_wait_call() the function will return,
corrupting the callback structure the stack is reused.

This PR fixes the issue by deleting the callback before exiting
in case the event does not occur.

a63fcb67b6 net: ip: net_mgmt: Prevent loss of event
The current implementation doesn't handle
re-entrant calls correctly, causing events
to get lost.

Under specific conditions, re-entrancy happens
from event callback done by net_mgmt.c back into
'net_mgmt_event_notify_with_info' causing circular
buffer administration corruption.

These conditions are:

- llmnr_iface_event_handler
- mdns_iface_event_handler
- wifi_mgmt_raise_connect_result_event
- dhcpv4_immediate_timeout uses a workaround

Validated the fix on a Nucleo_H743ZI, using an

b10428163a kernel: sem: add K_SEM_MAX_LIMIT
Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".

Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.

In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.

These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

4e5c093e66 kernel: demote K_THREAD_STACK_BUFFER() to private
This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.

As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.

The final work to remove this (and overhaul stack specification in
general) will take place in 1.15 in the context of #14269

65a9d2a94a kernel: make K_.*_INITIALIZER private to kernel
Upcoming memory protection features will be placing some additional
constraints on kernel objects:

- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.

Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.

It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.

There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.

k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.
