Some function return values were not handled. Added assert in case
those functions return error. It is possible only if same ring buffer
instance is used without any protection from multiple contexts.

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c
include/linker/kobject-text.ld
kernel/include/syscall_handler.h
scripts/gen_kobject_list.py
scripts/gen_syscall_header.py

Added __weak keyword to to support overriding assert_post_action().
This allows system designers to change/augment the assert behaviour,
i.e. add logging to persistant storage of program counter, line
number etc, and/or change reboot behaviour.

MISRA rules (see #11425) forbid recursive algorithms. In the case of
rb_walk(), it's not actually used anywhere but a test right now, so we
can simply disable the API when CONFIG_MISRA_SANE is defined. Mempool
had a (IMHO, fairly clever) tail recursive loop in bfree_recombine()
which can be trivially transformed into an only slightly uglier
iterative version.

MISRA rules (see #9892) forbid alloca() and family, even though those
features can be valuable performance and memory size optimizations
useful to Zephyr.
Introduce a MISRA_SANE kconfig, which when true enables a gcc error
condition whenever a variable length array is used.
When enabled, the mempool code will use a theoretical-maximum array
size on the stack instead of one tailored to the current pool
configuration.
The rbtree code will do similarly, but because the theoretical maximum
is quite a bit larger (236 bytes on 32 bit platforms) the array is
placed into struct rbtree instead so it can live in static data (and
also so I don't have to go and retune all the test stack sizes!).
Current code only uses at most two of these (one in the scheduler when
SCHED_SCALABLE is selected, and one for dynamic kernel objects when
USERSPACE and DYNAMIC_OBJECTS are set).
This tunable is false by default, but is selected in a single test (a
subcase of tests/kernel/common) for coverage. Note that the I2C and
SPI subsystems contain uncorrected VLAs, so a few platforms need to be
blacklisted with a filter.

These get references by newlib builds in other toolchains, e.g.
gnuarmemb, and lack of them breaks linking. Tested that
tests/posix/fs and tests/posix/common actually work with these
changes.

_impl__zephyr_write() was renamed to _impl__zephyr_write_stdout().
This wasn't caught by CI because we didn't have POSIX tests build
for newlib, but now we have.

There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.
This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.
All files that use these macros have been updated.

This was never a long-term solution, more of a gross hack
to get test cases working until we could figure out a good
end-to-end solution for memory domains that generated
appropriate linker sections. Now that we have this with
the app shared memory feature, and have converted all tests
to remove it, delete this feature.
To date all userspace APIs have been tagged as 'experimental'
which sidesteps deprecation policies.

After #12732, 6904501173
asserts call k_panic.
Before this, the POSIX arch had its own hack in the
__ASSERT_POST implementation to terminate the process instead
of spining forever.
But the POSIX arch does implement k_panic properly, so there
is no need anymore for this hack.
=> Remove the special treatment for POSIX ARCH

Replaced forever loop in assert with call to a function.
In post_assert_action() function, k_panic is called.
Forever loop was preventing logs to be printed and had behavior
ependent on the context (low prioriy thread - system continue to
ork, irq - system is blocked).
