Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
Most of the changes here are scripted, check the PR for more
info.

Move the syscall_handler.h header, used internally only to a dedicated

As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:
```python
from pathlib import Path

EXTENSIONS = ("c", "h", "cpp", "rst")
for p in Path(".").glob("samples/**/*"):
if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
continue
content = ""
with open(p) as f:
for line in f:
m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
if (m and
not m.group(2).startswith("zephyr/") and
(Path(".") / "include" / "zephyr" / m.group(2)).exists()):
content += (
m.group(1) +
"#include <zephyr/" + m.group(2) +">" +
m.group(3) + "\n"
)
else:
content += line
with open(p, "w") as f:
f.write(content)

Normally main.c file doesn't have a header file, because it doesn't
need to declare any interfaces to other modules.
In this sample, it's better to put the shared variables in one place,
and provide the interfaces to other modules, such as app_a, app_b,
and main.

This changes both k_mem_domain_add_partition() and
k_mem_domain_remove_partition() to return errors instead of
asserting when errors are encountered. This gives the application
chance to recover.
The arch_mem_domain_parition_add()/_remove() will be modified
later together with all the other arch_mem_domain_*() changes
since the architecture code for partition addition and removal
functions usually cannot be separately changed.

With demand paging, the main stack is not user mode capable
and it would fail k_thread_user_mode_enter() under
app_b_entry(). So create another thread and stack for app_b
as this stack can be used in user mode.

Use the core k_heap API pervasively within our tree instead of the
z_mem_pool wrapper that provided compatibility with the older mempool
implementation.
Almost all of this is straightforward swapping of one alloc/free call
for another. In a few cases where code was holding onto an old-style
"mem_block" a local compatibility struct with a single field has been
swapped in to keep the invasiveness of the changes down.
Note that not all the relevant changes in this patch have in-tree test
coverage, though I validated that it all builds.

This code used a sys_mem_pool directly. Use a new-style heap instead
to do the same thing.
(Note that the usage is a little specious -- it allocates from the
heap but doesn't appear to fill or check any data therein, just that
the heap memory can be copied from the two memory domains. It's
unclear exactly what this is trying to demonstrate and we might want
to improve the sample to do something less trivial.)

The k_mem_pool allocator is no more, and the z_mem_pool compatibility
API is going away. The internal allocator should be a k_heap always.

Mark all k_mem_pool APIs deprecated for future code. Remaining

Remove leading/trailing blank lines in .c, .h, .py, .rst, .yml, and
.yaml files.
Will avoid failures with the new CI test in
https://github.com/zephyrproject-rtos/ci-tools/pull/112, though it only
checks changed files.
Move the 'target-notes' target in boards/xtensa/odroid_go/doc/index.rst
to get rid of the trailing blank line there. It was probably misplaced.

We try to demonstrate some concepts for user mode:
- Multiple logical applications, each with their own memory
domain
- Creation of a sys_mem_pool and assignment to a memory
partition
- Use of APIs like k_queue_alloc_append() which require
thread resource pools to be configured
- Management of permissions for kernel objects and drivers
- Show how application-specific system calls are defined
- Show IPC between ISR and application (using k_msgq) and
application-to-application IPC (using k_queue)
