Variable "level" in function z_vrfy_log_filter_set() has type unsigned.
But it is been checked if "level >=LOG_LEVEL_NONE" and
LOG_LEVEL_NONE is 0. It means check if unsigned is ">= 0" in Z_OOPS().
That is logically wrong, because unsigned is ">=0" by default.
Remove that check, to avoid static analysis tool raise
violation
Found as a coding guideline violation (MISRA R14.3) by static

The k_mem_slab_init() calls create_free_list() which checks

Previously, a racing write to the provided metadata could result
in up to CONFIG_LOG_STRDUP_MAX_STRING-2 bytes after the
end of user-accessible memory being leaked into the strdup pool
or the resulting log.
For now, explicitly copy the metadata string. In an ideal world
this could directly copy from userspace into the strdup buffer, but
this obviously only works if strdup is enabled.

va_list was initialized once and passed to log_backend_put_sync_string()
for each logging backend. State of such va_list was changed in each
execution, resulting in different va_list state to be passed for
consecutive log_backend_put_sync_string() calls. This results in
undefined behavior and program crashes.
Use va_copy() to copy va_list state to temporary variable for each
logging backend and keep original va_list untouched. Pass such temporary
state to log_backend_put_sync_string() to make sure state for all
consecutive calls does not change.

MISRA-C Rule 5.3 states that identifiers in inner scope should
not hide identifiers in outer scope.
The log output instances all named "log_output" in backends
collide with the "log_output" parameter of various functions.
This renames the variables in the backends to make them
more descriptive. Same goes for the buffers for some of
these instances as they are all named "buf", and "hostname"
being used in the network backend, so they are renamed.
There are a few places where variables are overriden within
an inner scope (e.g. inside loop and if block) so they are
also renamed.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

Previously, there were two issues when attempting to use LOG_HEXDUMP_*
from C++:
First, gcc and clang in C mode both allow implicit pointer conversion
by default, but require -fpermissive, which no one should ever use, in
C++ mode. Furthermore, -Wpointer-sign, the warning emitted in C for
convertion between pointers to types of different signedness (e.g. char*
vs u8_t*) is explicitly disabled in Zephyr. Switch the various hexdump
functions to void*, which is guaranteed to work in both languages.
Second, the soon-to-be-standardized C++20 version of designated
initializers requires that the designators appear in the same order as
they are declared in the type being initialized.

In the count_s() function, with -Wchar-subscripts, GCC warns

Commit ad28c2d6 introduced semaphore on which logger thread
pends. It is possible that log messages are created before
any backend is attached. In that case, logger thread pends
on semaphore with pending log messages and is not waken up
unless new log messages comes.
Fixed by setting semaphore when first backend is attached.
This wakes up logger thread and log messages can be processed.

This commit adds basic userspace support to the logging subsystem.
With this change, the following API could be called from user mode:
- LOG_*()
- LOG_INST_*(),
- LOG_HEXDUMP_*(),
- LOG_HEXDUMP_INST_*(),
- LOG_PANIC(), LOG_PROCESS(),
- log_printk(), log_generic(), log_buffrered_cnt(),
- log_filter_set(NULL, ...)
With userspace disabled, the logger behavior and performance
is not affected. With userspace enabled, the calls from kernel
space have an additional overhead introduced by _is_user_context().
The logger behavior changes when it is called from the user context.
All strings logged using LOG_*() and LOG_INST_*() API from userspace
are rendered in place for security reasons and then placed in
log_strdup() memory pool, which should be large enough to hold bursts
of log messages.

On such platforms using CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC define
