The current policy of always excluding stacks that aren't
owned by the current thread only works well on MPU systems,
where it is very fast to have a reserved MPU region corresponding
to the stack buffer of the current thread.
This unfortunately is not efficient on MMU-based systems, it
would require either a different set of page tables per thread
or an expensive page table update on context switch.
This PR relaxes the documented policy to leave it up to the
implementation whether threads that all belong to the same
memory domain can see each other's stacks.
There's lots of precedent for this, for example on Linux threads
in the same process can all access each other's stacks.

The legacy macros were first deprecated in Zephyr v2.3. Now that
Zephyr v2.4 has been released, that makes two releases where these
macros have been deprecated, so it's OK to remove them.
This leaves support for legacy binding syntax in place. Removing that
is left to future work.
We need to update various pieces of documentation related to flash
partitions that never got updated when the new API was introduced.
Consolidate this information in the flash_map.h API reference page,
since that's really where users will run into it. This also gives us
the opportunity to improve this documentation.
Adjust a couple of kconfigfunctions.py and sanitycheck bits to use
non-legacy edtlib APIs.

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.

Currently, after `CONFIG_LWM2M_RD_CLIENT_SUPPORT_BOOTSTRAP` is enabled,
the LwM2M engine will initiate bootstrap procedure on each run. This
approach limits the flexibility of the application, as it's not always
necessary to go over the bootstrap procedure (for instance, the
application may decide to store the security object obtained during the
bootstrap in flash, and restore it on boot).
Fix this by introducing an additional `flags` parameter to the
`lwm2m_rd_client_start()` function, which provides information whether
to run bootstrap in the current session or not.

The documentation claims that Zephyr supports external file system
implementations, and there's no reason not to do so. Rework the API
to allow this.
Note that the file system type cannot legally be an enum anymore,
since we need to support file system types that don't have an
identifier assigned in that enum. Rely on the implicit conversion of
enum values to int to preserve backwards compatibility.

The on-off manager infrastructure is designed to robust asynchronous
transition between binary states where multiple clients may be
initiating a transition from any context. The actual transition is
performed using a manager that tracks the current state and pending
operations. Requests are initiated by passing a reference to an
onoff_client object that holds client state including the notification
mechanism.
This API may be used in subsystems where the transitions for a
particular driver are always synchronous and isr-ok, e.g. setting a
SoC-controlled GPIO. In this situation the full on-off manager
infrastructure is wasteful. All we need is a record of the service
state: off, active count, or error.
Add a data structure and an API that can be used to replace the onoff
manager functionality in a situation where all transitions are isr-ok
and synchronous while retaining compatible behavior from the client
perspective.

There is nothing wrong with instance numbers and they are
recommended for use whenever possible, but this is an API
design problem because it's not always possible to get nodes
by instance number; in some cases, drivers need to get node
identifiers from node labels, for example.
Change these APIs (which are not yet in any Zephyr release)
to take node IDs instead of instance IDs.

This device isn't an actual hardware driver: it's a virtual EEPROM
that stores data in an instance-specific RAM buffer, with the data
exposed on an I2C bus as a I2C follower (slave) device that can be
controlled by another device acting as a leader (master) on that same
bus.
As such it's a reasonable example of how to write an I2C follower
driver, but it's not clear that it has a real use in applications. A
Zephyr application that needs to emulate an EEPROM in a real-world
system would be unlikely to provide its data from a RAM buffer.
The sole in-tree reference is in the i2c_slave_api test, so move the
driver implementation into that test.
The Kconfig and hierarchy are being left in place until it is more
clear how this functionality should be selectable within Zephyr. The
I2C_SLAVE symbol has been converted from menuconfig to config to
eliminate a Kconfig style diagnostic.
