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.

Convert samples to DEVICE_{DT_}DEFINE instead of DEVICE_AND_API_INIT
so we can deprecate DEVICE_AND_API_INIT in the future.

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
internal usage now uses equivalent "z_mem_pool" symbols instead.

Memory domains can be very expensive to instantiate. Demonstrate
how the default memory domain can be re-purposed for an
application, much like how the main thread already is.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

-struct device *

This change removes the hardcoded subsystem list in gen_kobject_list.py
favor of marking the relevant driver API structs with the _subsystem
sentinel.

The application main() in Zephyr is defined as having a prototype:
void main(void), as expected by the kernel init (bg_thread_main).
So, correct the different samples and tests that were defined
otherwise.

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)
