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.

b2435d856a tests/kernel/threads/thread_apis: Add k_thread_suspend() edge cases
Add test cases to make sure that a thread that suspends itself stops
executing immediately, and that a thread suspended while sleeping does
not wake up unexpectedly when its timeout expires.

fe031611fd kernel: rename main/idle thread/stacks
The main and idle threads, and their associated stacks,
were being referenced in various parts of the kernel
with no central definition. Expose these in kernel_internal.h
and namespace with z_ appropriately.

The main and idle threads were being defined statically,
with another variable exposed to contain their pointer
value. This wastes a bit of memory and isn't accessible
to user threads anyway, just expose the actual thread
objects.

Redundance MAIN_STACK_SIZE and IDLE_STACK_SIZE defines
in init.c removed, just use the Kconfigs they derive
from.

d1200d2155 tests: Never disable SMP
Disabling SMP mode for certain tests was a one-release thing, done to
avoid having to triage every test independently (MANY are not
SMP-safe), and with the knowledge that it was probably hiding bugs in
the kernel.

Turn it on pervasively.  Tests are treated with a combination of
flagging specific cases as "1cpu" where we have short-running tests
that can be independently run in an otherwise SMP environment, and via
setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still
runs the full SMP kernel config, but with only one CPU available).

38129ce1a6 kernel: fix CONFIG_THREAD_NAME from user mode.
This mechanism had multiple problems:

- Missing parameter documentation strings.
- Multiple calls to k_thread_name_set() from user
  mode would leak memory, since the copied string was never
  freed
- k_thread_name_get() returns memory to user mode
  with no guarantees on whether user mode can actually
  read it; in the case where the string was in thread
  resource pool memory (which happens when k_thread_name_set()
  is called from user mode) it would never be readable.
- There was no test case coverage for these functions
  from user mode.

To properly fix this, thread objects now have a buffer region
reserved specifically for the thread name. Setting the thread
name copies the string into the buffer. Getting the thread name
with k_thread_name_get() still returns a pointer, but the
system call has been removed. A new API k_thread_name_copy()
is introduced to copy the thread name into a destination buffer,
and a system call has been provided for that instead.

We now have full test case coverge for these APIs in both user
and supervisor mode.

Some of the code has been cleaned up to place system call
handler functions in proximity with their implementations.

6311766d9a pointer-type args: cast appropriately to be 64-bit compatible
Using void pointers as universal arguments is widely used. However, when
compiling a 64-bit target, the compiler doesn't like when an int is
converted to a pointer and vice versa despite the presence of a cast.
This is due to a width mismatch between ints (32 bits) and pointers
(64 bits). The trick is to cast to a widening integer type such as
intptr_t and then cast to
void*.

When appropriate, the INT_TO_POINTER macro is used instead of this
double cast to make things clearer. The converse with POINTER_TO_INT
is also done which also serves as good code annotations.

While at it, remove unneeded casts to specific pointer types from void*
in the vicinity, and move to typed variable upon function entry to make
the code cleaner.

4344e27c26 all: Update reserved function names
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

41f6011c36 userspace: remove APPLICATION_MEMORY feature
This was never a long-term solution, more of a gross hack
to get test cases working until we could figure out a good
end-to-end solution for memory domains that generated
appropriate linker sections. Now that we have this with
the app shared memory feature, and have converted all tests
to remove it, delete this feature.

To date all userspace APIs have been tagged as 'experimental'
which sidesteps deprecation policies.
