It's useful to be able to inspect the key returned from
z_arch_irq_unlock() to see if interrupts were enabled at the point
where z_arch_irq_lock() was called. Architectures tend to represent
this is a simple way that doesn't require platform assembly to
inspect.
Adds a simple test to kernel/common that validates this predicate with
a nested lock.

The struct _caller_saved is not used. Most architectures put
automatically the registers onto stack, in others architectures the
exception code does it.

The struct _kernel_ach exists only because ARC' s port needed it, in
all other ports this was defined as an empty struct. Turns out that
this struct is not required even for ARC anymore, this is a legacy
code from nanokernel time.

The legacy struct s_coopFloatReg was never being used, though it was
an empty struct (not wasting space), some symbols were being generate
for it.
Nevertheless, neither C99 nor C11 allow empty structs, so this
was also a violation to the C standards.

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

There is no need to rename the POSIX types, so let's not do it to
simplify things
Also remove an unnecessary guard (POSIX_ARCH) to avoid mystifying
this any more than necessary

In 8dc69e09da (#10280)
the POSIX API main kconfig option was replaced from
PTHREAD_IPC to POSIX_API.
But the posix_cheats.h header was left using the old option.
This means that some applications/tests which were not
selecting the PTHREAD_IPC API, but using some other Zephyr
POSIX compatible APIs could have trouble when compiled for the
POSIX architecture.

Always compare unsigned interger type with another unsigned

we were comparing the _kernel.nested variable with a signed
interger type. Fixed this violation.

Added a basic command line parameter parsing framework
Added the following options by now:
--stop-at=<time>: Auto-stop after <time> seconds
--seed=<seed> : random seed for entropy device
--testargs : any argument that follows is ignored in top level
and made available thru
native_get_test_cmd_line_args()
All command line parameters are still avaliable by calling
native_get_cmd_line_args(), but now you can also call
native_get_test_cmd_line_args() to get whatever was set after
--testargs
