This provides memory mappings with the ability to be initialized in their
paged-out state and be paged in on demand. This is especially nice for
anonymous memory mappings as they no longer have to allocate all memory
at mem_map time. This also allows for file mappings to be implemented by
simply providing backing store location tokens.

Using DEVICE_DEFINE, a device without a corresponding DT node can be
defined (for example CRYPTO_MTLS), Z_DEVICE_INIT() does not initialize
dt_meta for such devices, leaving the field as NULL.
device_get_dt_nodelabels() and functions calling it have to handle
dev->dt_meta == NULL to prevent fatal errors.

When logging is on and optimization and multithreading is off then
build fails to link because unoptimized compiler/linker seems to not
look beyond the function and it fails trying to link k_thread_name_get.
Reworking the code to make it known to the compiler without optimization
that k_thread_name_get is not needed and not logging current thread
name in that case.

Removes the ISR restriction from k_thread_priority_set().
Since the first commit, the routine k_thread_priority_set() has

be a reason why the restriction exists, it is being removed.

PR #63973 namespaced generated headers with zephyr/, including generated

native_posix (unlike native_sim) or its breathen (NATIVE_APPLICATION)
link together the "runner" code and the embedded code.
This means that when CONFIG_STATIC_INIT_GNU is set,
any host library code (like the llvm fuzzer) constructors will get
postponed to the Zephyr initialization.
These libraries are unlikely to work if we do this.
(the llvm fuzzer does not)
So let's instead not enable STATIC_INIT_GNU for these targets.
This means possible embedded library constructors will continue to be
picked during the link and be still called during the native runner
initialization instead of during the Zephyr OS initialization as they
were just before we introduced STATIC_INIT_GNU in
6e977ae2d5
Note that native_posix will be deprecated shortly and its users
are strongly encouraged to move to native_sim.

In device init phase, it will call _mbedtls_init before malloc_prepare
as mbedtls has higher priority defined in SYS_INIT..
_mbedtls_init() will call psa_crypto_init() and malloc buffer,
but z_malloc_heap is not initialized, which will cause device hang.
Should call malloc_prepare() before _mbedtls_init to fix this issue,
so add new Kconfig to increase the priority of libc to deafult 30.

to the kernel library, as this is common for both C

* Rename the hidden kconfig option CPP_STATIC_INIT_GNU

* If STATIC_INIT_GNU is not selected verify there is

Extern declaration of __stack_chk_guard added volatile to
the type while the declaration was non-volatile. This cause
type check errors with compilers that declares the
__stack_chk_guard variable in an internal pre-include

on keep it and add it to the declaration in
