k_thread_name_get has inconsistent signature. In the function
declaration it uses k_tid_t but in the implementation it is using
struct k_thread *. Change the implementation to use k_tid_t.

virt_page_phys_get can be called with phy parameter NULL when
the intention is just checking if a virtual address is mapped.
This function is generally overwritten by a an arch API that checks if
phys is null before using it but this default implementation doesn't.

Thread userspace local data is to be used with storing errno per
thread without thread local storage support. However, if the C
library has native errno support, there is no need to enable
thread userspace local data to store errno per thread. Therefore,
amend the default for CONFIG_THREAD_USERSPACE_LOCAL_DATA so that
it is not enabled if the C library has native errno support.

The documentation suggests that k_timer_start can be invoked from ISR
and preemptive contexts, however, an assertion failure occurs if one
k_timer_start call preempts another for the same timer instance. This
commit mitigates the issue by implementing a spinlock throughout the
k_timer_start function, ensuring thread-safety.
Fixes: #62908

Sometimes the generic address range checker is not adequate
(think Xtensa cached/uncached pointers). This provides a way
to implement custom memory range checkers for those
situations. When enabled, sys_mm_is_phys_addr_in_range()
and sys_mm_is_virt_addr_in_range() must be implemented.

The early random get function was making many wrong assumptions
about random subsys and entropy drivers. First, it was assuming
that entropy_get_entropy() would be ISR safe, that is not right,
the driver has an ISR safe callback and if it is not implemented
or not working it is not ok using the other callback.
Second, the fallback to the random subsys is even more problematic
since they can use kernel services to protect internal states and be
thread-safe.
Another incorrect thing in this function was the guard around it.
It was needed by features like stack randomization and stack canaries,
and not when those conditions were match. Just remove it and in case
it is not needed the linker will take care of it.
The drawback of this change is that in the absence of an entropy
generator with support to be called from ISR the randomness is very
weak.

Platforms that determine their basic timer frequency at runtime instead of
build time cannot compute thread initialization timeouts during
compilation.
Switch back to storing the init_delay value in milliseconds and perform the
conversion to a k_timeout_t at runtime.

Instead of adding every possible subsystem which places variables in the C
library memory partition in libc-hooks.h, place those conditions in the

CONFIG_NEED_LIBC_MEM_PARTITION.

rand32.h does not make much sense, since the random subsystem
provides more APIs than just getting a random 32 bits value.
Rename it to random.h and get consistently with other

Assert that the handler of a work is not NULL when submitting
it to the queue. This allows early detection of the
code that is submitting a non-NULL work with NULL handler to
the work queue (where it happens), rather than right before the
work item get executed in the queue (when it happens).

Zephyr's code base uses MP_MAX_NUM_CPUS to
know how many cores exists in the target. It is
also expected that both symbols MP_MAX_NUM_CPUS
and MP_NUM_CPUS have the same value, so lets
just use MP_MAX_NUM_CPUS and simplify it.
