Replace the condition-less `for` loop (`;;`) in `get_child_of` with
a `while (true)` loop and remove the redundant `return NULL;`
at the end, which is never reached.
This change aims to enhance readability since `while (true)` is better
suited for this scenario.

Packet buffer can be used for sharing data between cores. In that
case when any core has data cache then data cache handling must
be enabled in the module. However, it shall never be enabled when
the packet buffer is used on a single core. Adding that information

__z_clock_nanosleep function was getting current time in cycles, via
k_cycle_get_32(), to perform its time calculations. However, when calling
k_sleep() to actually sleep, times are measured in ticks.
This causes a problem when there's a big skew between the uptime
measured in cycles vs uptime measured in ticks: in some platforms, the
system clock maybe up for a long time already when Zephyr starts
counting ticks, for instance, while downloading an image via PXE. In
this case, the calculations done inside __z_clock_nanosleep end up
measuring a much bigger current time than expected, thus sleeping too
much, basically all the time since system clock initialization.
This patch fixes that by avoiding the cycle trip: stick to ticks,
instead. They start counting from Zephyr initialization instead, which
is the expected uptime.

Move the implementation of zsock_select() to zvfs_select(). This
allows other types of file descriptors to also make use of
select() functionality even when the network subsystem is not
enabled.
Additionally, it partially removes a dependency cycle between
posix and networking by moving functionality into a mutual
dependency.

The POSIX_DEVICE_IO Option Group requires a number of c89
functions mainly from stdio.h .
Namely,
clearerr(), fclose(), feof(), ferror(), fflush(), fetc(),
fgets(), fprintf(), fputc(), fputs(), fread(), freopen(),
fscanf(), fwrite(), getc(), getchar(), gets(), perror(),
printf(), putc(), putchar(), puts(), scanf(), setbuf(),
setvbuf(), ungetc(), vfprintf(), vfscanf(), vfprintf(), and
vscanf().
These should be provided by any conformant C library
(not by the POSIX API).

Only invoke vtable methods read, write, and close if they are
non-NULL.
The close() vtable method is optional, so that should not return
an error if zvfs_close() is called and that method is
unimplemented.
Otherwise, if zvfs_read() or zvfs_write() are called and the
corresponding vtable method is unimplemented, fail setting
errno to EIO.

Make it easier for external C libraries, toolchains, and
integrators to override Zephyr's implementation of functions and
sybmols on a per-Option-Group basis.
This change adds a number of non-user-configurable Kconfig
options that block internal Cmake rules from building Zephyr's
C sources corresponding to the particular option.
This is useful, for example, if a specific C library has a smaller,
or faster, or more secure version of some symbols belonging to a
a particular option group.

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.

For each of the fdtable.h functions listed below, convert the
z_ prefixed semi-private functions to use the zvfs_ prefix.
ZVFS stands for Zephyr Virtual File System and
is intended to be a common library used by the C library,
POSIX API, Networking, Filesystem, and other areas.
There are already a few functions in fdtable.h that use the
zvfs_ prefix, so this change is mostly about unifying them in
a way that uses a suitable prefix ("namespace") so that it can
be considered a public API.
- z_alloc_fd
- z_fdtable_call_ioctl
- z_finalize_fd
- z_finalize_typed_fd
- z_free_fd
- z_get_fd_obj
- z_get_fd_obj_and_vtable
- z_get_obj_lock_and_cond
- z_reserve_fd

to the kernel library, as this is common for both C
and C++ and it is the kernel who is running it.
* Rename the hidden kconfig option CPP_STATIC_INIT_GNU
STATIC_INIT_GNU instead.
* If STATIC_INIT_GNU is not selected verify there is
constructors left behind.
* Rename common-rom-cpp.ld to common-rom-init.ld
* Rename z_cpp_init_static to z_init_static,
and have the kernel always call it.

Both Clang [1] and (recently) GCC [2] support this flag to enable
additional codesize optimizations beyond -Os, possibly at the expense of
performance.
This tradeoff is worthwhile for some (and, Clang's -Oz seems to be
closer to GCC's -Os currently), so add a new abstraction for this flag
so users can select it as appropriate.
