This is a simple shell module that allows arbitrary boards with flash
driver support to explore the flash device.
- Reading, erasing, and writing by device offsets are supported in all
cases.
- If the flash page layout is available, it can be printed, and I/O
can also be done to a specified page as well.
One known issue is that writing to flash on targets that require
doubleword-sized writes (e.g STM32L4) will fail since the number of
arguments required exceeds ARGC_MAX in shell.c. Addressing that is
left to future work.

L4 parts have a constant page size, so just rely on the HAL defines
that provide it, along with a read to the register which contains this
SoC's total size.

Add flash page layout support for STM32F4 SoCs.
This almost eliminates the need for flash_map.h, except for
STM32F4X_SECTOR_MASK, so delete the file and move the define into the
F4 implementation, to keep things simple.

This is a prep work commit for adding flash page layout support.
The internal flash APIs for STM32 on L4 and F4 are a bit
inconsistent. Some routines take a pointer to the private data, others
don't. Those that do take it as a last argument instead of a
first. Additionally, some APIs are declared in flash_stm32.h that
aren't ever used by the family-specific files.
Clean this up by making everything take a struct device*, and marking
routines static in the common driver code when possible.

Added sample code for testing and displaying the flash layout using
the recently introduced API.

Added an internal function to obtain the flash page layout in
run-length encoded format. The API is simple and allows the actual
public API implementations to be simple and maintainable.
This feature can be enabled by using the FLASH_PAGE_LAYOUT Kconfig
option. This API is required for the implementation of flash file
system.
Added a public API to get flash page information (size and start offset)
by offset within the flash and by index of the page.
Added a generic implementation of the internal flash_get_page_info API.
Added an additional public API call to get the total count of pages in
the flash memory and its generic implementation.

This was felt to be necessary at one point but actually isn't.
- When a thread is initialized to use a particular stack, calls will be
made to the MMU/MPU to restrict access to that stack to only that
thread. Once a stack is in use, it will not be generally readable even
if the buffer exists in application memory space.
- If a user thread wants to create a thread, we will need to have some
way to ensure that whatever stack buffer passed in is unused and
appropriate. Since unused stacks in application memory will be generally
accessible, we can just check that the calling thread to
k_thread_create() has access to the stack buffer passed in, it won't if
the stack is in use.
On ARM we had a linker definition for .stacks, but currently stacks are
just tagged with __noinit (which is fine).

prepare_arp() was unreferencing original pkt (called pending there) in
case of error.
net_prepare_arp() was always unreferencing pkt, though it could have
been already unreferenced by prepare_arp() as seen previously which is
an extra bogus unref in this case.
And in case it returned NULL, ethernet_send() would return NET_DROP
which in turn would make net_if's tx code to unref again the pkt.
This patch ensures pkt is unrefed only once and at the right place.

Previously, this was only done if an essential thread self-exited,
and was a runtime check that generated a kernel panic.
Now if any thread has k_thread_abort() called on it, and that thread
is essential to the system operation, this check is made. It is now
an assertion.
_NANO_ERR_INVALID_TASK_EXIT checks and printouts removed since this
is now an assertion.

It's now possible to instantiate a thread object, but delay its
execution indefinitely. This was already supported with K_THREAD_DEFINE.
A new API, k_thread_start(), now exists to start threads that are in
this state.
The intended use-case is to initialize a thread with K_USER, then grant
it various access permissions, and only then start it.
