cbff3e34d7 doc: kernel: workqueue: correct documentation of delayed work API
The delayed work API has been changed to allow cancellation in
conditions not previously documented, but this feature can cause both
submission and cancellation to fail in the general case.  Summarize
the conditions and highlight the importance of checking result codes
for these functions.

Also explicitly note that no kernel API can reliably indicate that a
work item has been completed, and that doing so is the responsibility
of the code that provides the work handler.

c79d2ce794 doc: update struct references to use :c:struct:
Sphinx>=3.0 includes the `struct` role in the C domain, which provides a
specific way to link to structs, while the old :c:type: role should be
primary used to typedefs. Update existing references, using :c:type:,
:cpp:type: or emphasized symbols that point to structs to use the new
role.

53fd5ff236 doc: update function references to use :c:func:
Following the change to use the C domain for parsing, update all
existing :cpp:func: references to :c:func:. Remove the parentheses as
well, if used, because they are not needed, this is already known to be
a function, and how it is displayed in the documentation later is a
semantic decision done by the output builder.

fc68feea70 doc: add kernel/thread stack usage notes
This is covered in the porting guide, and we have complete docstrings
for these macros, but having discussion here helps new users understand
how to use these and why they exist.

3318ad3dfb doc: kernel: Fix invalid use of K_NO_WAIT
K_THREAD_DEFINE can no longer use K_NO_WAIT to specify the delay after
the timer API rework. Fix the documentation to use 0 and add a note.

Fixes #25697.

984bfae831 global: Remove leading/trailing blank lines in files
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.

d803a534c0 docs: kernel: thread documentation enhancements and cleanup
Moving all thread docs into 1 page was a bit too much. Split the section
a bit and remove redundant and useless sections and move some thread
related documentation from the scheduling page to threads (thread states
and priorities).

Add a new figure for thread states.
