move misc/stack.h to debug/stack.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

We had both kernel and os as domains covering low level layers, just use
one and fix the issue of the os domain not being registered.

This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.
As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.
The final work to remove this (and overhaul stack specification in
general) will take place in 1.15 in the context of #14269Fixes: #14766

When printk is used stack size expanding may be needed. This is
especially a problem for threads with small stacks.

comparing int i with size_t size generates a sign-compare warning.
This commit solves the issue by giving i the type needed.
As older c standards do not allow to declare i after stack += 4 I
inserted the variable checked_stack that gets the type we need in the
comparison.

Avoid listing internal function in the public API documentation. After
enabling those doxygen configs, we go lots of errors and bad refs that
were fixed.

This was previously just a #define in one header file, but we need
this expressed in Kconfig space in case some feature only works
properly with downward-growing stacks.

This function wasn't working on systems that enabled the stack
sentinel as the first 4 bytes of the stack buffer contain the
sentinel value for thread stacks.

The existing __stack decorator is not flexible enough for upcoming
thread stack memory protection scenarios. Wrap the entire thing in
a declaration macro abstraction instead, which can be implemented
on a per-arch or per-SOC basis.

The computation of unused stack space is now split off from the function
which sends the result to printk().
The code now assumes that the struct k_thread is stored elsewhere.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

There was a lot of duplication between architectures for the definition
of threads and the "nanokernel" guts. These have been consolidated.
Now, a common file kernel/unified/include/kernel_structs.h holds the
common definitions. Architectures provide two files to complement it:
kernel_arch_data.h and kernel_arch_func.h. The first one contains at
least the struct _thread_arch and struct _kernel_arch data structures,
as well as the struct _callee_saved and struct _caller_saved register
layouts. The second file contains anything that needs what is provided
by the common stuff in kernel_structs.h. Those two files are only meant
to be included in kernel_structs.h in very specific locations.
The thread data structure has been separated into three major parts:
common struct _thread_base and struct k_thread, and arch-specific struct
_thread_arch. The first and third ones are included in the second.
The struct s_NANO data structure has been split into two: common struct
_kernel and arch-specific struct _kernel_arch. The latter is included in
the former.
Offsets files have also changed: nano_offsets.h has been renamed
kernel_offsets.h and is still included by the arch-specific offsets.c.
Also, since the thread and kernel data structures are now made of
sub-structures, offsets have to be added to make up the full offset.
Some of these additions have been consolidated in shorter symbols,
available from kernel/unified/include/offsets_short.h, which includes an
arch-specific offsets_arch_short.h. Most of the code include
offsets_short.h now instead of offsets.h.

The helper for analyzing (fiber) stack usage is in no way specific to
Bluetooth and will likely be of use to many other places as well. Move
it therefore to include/misc.
