When printk is redirected to the logging it is using level 0.
Level 0 was missing a define used for detection of function
prefix use which lead to compilation failure when logging v2
was used with CONFIG_LOG_PRINTK=y.

Logging attempts to do most of the work at compile time instead
of preprocessor by using conditions which can be resolved at
compile time (e.g. if (IS_ENABLED(...))). Apparently, such extensive
use significantly loads the compiler since all paths are compiled
even though cut from final binary. Patch reduces it by replacing
some compile time switch with preprocessor.
Handling of function name prefix has been moved to preprocessor.
Immediate logging v2 has also been moved to preprocessor.

So far we only have log_msg_timestamp_get() function, which returns
internal timestamp representation. This is either clock cycles or uptime
in ms, depending on main clock precision.
Introduce log_output_timestamp_to_us() helper function, which allows to
convert internal logging timestamp to us.

Change a runtime log check such that Coverity does not report a
needless issue on every use of any log macro.
Before the change, this was used in log macros:
else if(is_user_context || (_level <= LOG_RUNTIME_FILTER(_filter)))
If runtime filtering is not enabled, this expands to:
else if(is_user_context || 1)
Because the level is compared to log level debug (4) and will always be,
equal or lower.
Coverity always reports this as a potential issue, since the
variable part (is_user_context) makes no difference.
After the change, a macro is used which expands into the original code
when runtime filtering is used, else it simply expands to:
else if(true)
Which has equal semantics as the previous code but isn't flagged by
Coverity.

MISRA-C Directive 4.7 says that error information returned from
a function needs to be tested. In the logging macros,
return from _is_user_context() is not needed until logging is
enabled and above minimal logging level. There is a potential
that the return is not being used at all. So move it one level
below as it is surely being used within the if block.

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.

The log mechanism, even in immediate mode, adds somewhere
between 1K-2K of footprint to applications that use it.
We want to standardize the logging APIs for all logging
within the kernel, but need to not let platforms with
very constrained RAM/ROM in the dust.
This patch introduces CONFIG_LOG_MINIMAL, which is a very
thin wrapper to printk(). It supports the APIs expressed
in logging/log.h.
This will be the new default for test cases.
