5ba0c8e0c5 arch: arm: Inline arch_isr_direct_header.
This commit inlines arch_isr_direct_header function that was previously
placed in irq_manage.c for no good reason (possibly in relation to the
FIXME for #3056).

In addition, since the PR #20119 resolved the header circular
dependency issue described in the issue #3056, this commit removes the
references to it in the code.

The reason for not inlining _arch_is_direct_pm as the #3056 FIXME
suggests is that there is little to gain from doing so and there still
exists circular dependency for the headers required by this function
(#20119 only addresses kernel_structs.h, which is required for _current
and _kernel, which, in turn, is required for handling interrupt nesting
in many architectures; in fact, Cortex-A and Cortex-R port will require
it as well).

The new conversion API has a ton of generated utilities.  Test it via
enumerating each one of them and throwing a selection of both

370c39516b kernel: Add new uniform time unit conversion API
Zephyr has always had an ad hoc collection of time unit macros and
conversion routines in a selection of different units, precisions,
rounding modes and naming conventions.

This adds a single optimized generator to produce any such conversion,
and enumerates it to produce a collection of 48 utilities in all
useful combinations as a single supported kernel API going forward.

0151d6dc33 Bluetooth: Mesh: Model extension concept
Adds the model extension concept to the access layer, as described in
the Mesh Profile Specification, Section 2.3.6. Extensions are
implemented as a tree, using two pointers in each model:

The extends pointer points to the first extended model, and the next
pointer points to the next sibling or (if the NEXT_IS_PARENT flag is
set) the parent model in the tree, forming a cyclical "Left-child
right-sibling" (LCRS) tree. The tree root can be obtained by calling
bt_mesh_model_root_get(), and the extended models can be walked by
calling bt_mesh_model_tree_walk().

According to the Mesh Profile Specification Section 4.2.3, all models in
the same extension tree share one subscription list per element. This is
implemented by walking the model's extension tree, and pooling the
subscription lists of all models in the same element into one. If the
config server adds a subscription to a model, it may be stored in any of
the model tree's models' subscription lists. No two models in the same
extension tree and element will have duplicate groups listed. This
allows us to increase extended models' capacity for subscriptions
significantly.

2d7460482d headers: Refactor kernel and arch headers.
This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.

The refactoring strategy used in this commit is detailed in the issue

This commit introduces the following major changes:

1. Establish a clear boundary between private and public headers by
  removing "kernel/include" and "arch/*/include" from the global
  include paths. Ideally, only kernel/ and arch/*/ source files should
  reference the headers in these directories. If these headers must be
  used by a component, these include paths shall be manually added to
  the CMakeLists.txt file of the component. This is intended to
  discourage applications from including private kernel and arch
  headers either knowingly and unknowingly.

  - kernel/include/ (PRIVATE)
    This directory contains the private headers that provide private
   kernel definitions which should not be visible outside the kernel
   and arch source code. All public kernel definitions must be added
   to an appropriate header located under include/.

  - arch/*/include/ (PRIVATE)
    This directory contains the private headers that provide private
   architecture-specific definitions which should not be visible
   outside the arch and kernel source code. All public architecture-
   specific definitions must be added to an appropriate header located
   under include/arch/*/.

  - include/ AND include/sys/ (PUBLIC)
    This directory contains the public headers that provide public
   kernel definitions which can be referenced by both kernel and
   application code.

  - include/arch/*/ (PUBLIC)
    This directory contains the public headers that provide public
   architecture-specific definitions which can be referenced by both
   kernel and application code.

2. Split arch_interface.h into "kernel-to-arch interface" and "public
  arch interface" divisions.

  - kernel/include/kernel_arch_interface.h
    * provides private "kernel-to-arch interface" definition.
    * includes arch/*/include/kernel_arch_func.h to ensure that the
     interface function implementations are always available.
    * includes sys/arch_interface.h so that public arch interface
     definitions are automatically included when including this file.

  - arch/*/include/kernel_arch_func.h
    * provides architecture-specific "kernel-to-arch interface"
     implementation.
    * only the functions that will be used in kernel and arch source
     files are defined here.

  - include/sys/arch_interface.h
    * provides "public arch interface" definition.
    * includes include/arch/arch_inlines.h to ensure that the
     architecture-specific public inline interface function
     implementations are always available.

  - include/arch/arch_inlines.h
    * includes architecture-specific arch_inlines.h in
     include/arch/*/arch_inline.h.

  - include/arch/*/arch_inline.h
    * provides architecture-specific "public arch interface" inline
     function implementation.
    * supersedes include/sys/arch_inline.h.

3. Refactor kernel and the existing architecture implementations.

  - Remove circular dependency of kernel and arch headers. The
   following general rules should be observed:

    * Never include any private headers from public headers
    * Never include kernel_internal.h in kernel_arch_data.h
    * Always include kernel_arch_data.h from kernel_arch_func.h
    * Never include kernel.h from kernel_struct.h either directly or
     indirectly. Only add the kernel structures that must be referenced
     from public arch headers in this file.

  - Relocate syscall_handler.h to include/ so it can be used in the
   public code. This is necessary because many user-mode public codes
   reference the functions defined in this header.

  - Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
   necessary to provide architecture-specific thread definition for
   'struct k_thread' in kernel.h.

  - Remove any private header dependencies from public headers using
   the following methods:

    * If dependency is not required, simply omit
    * If dependency is required,
      - Relocate a portion of the required dependencies from the
       private header to an appropriate public header OR
      - Relocate the required private header to make it public.

80669decce Bluetooth: Mesh: Add support for provisioner role over PB-ADV
Make it possible to provision devices over advertising bearer (PB-ADV).
Many messages in the provisioning protocol are the same for provisioner
and device so much of the code could be reused by only changing when
they are expected to arrive.

This introduces to concept of local and remote device keys. The models
for cfg_cli and cfg_srv have been updated to reflect this concept. Both
the send and receive path in the transport layer have been updated to
support encrypting/decrypting with local and remote device keys.

When a node has been provisioned it is stored in bt_mesh_net.nodes. If
CONFIG_BT_SETTINGS is enabled, they are also saved to settings. If the
callback node_added in bt_mesh_prov has been set, it will be called for
every node that gets provisioned. This includes when they are retrieved
from settings.

The configuration CONFIG_BT_MESH_NODE_COUNT controls how many nodes that
can be provisioned.

d88f25bd76 net: tcp: Handle special case where accepted socket is closed
Handle this corner case with TCP connection closing:

1) Client A connects, it is accepted and can send data to us
2) Client B connects, the application needs to call accept()
   before we will receive any data from client A to the application.
   The app has not yet called accept() at this point (for
   whatever reason).
3) Client B then disconnects and we receive FIN. The connection
   cleanup is a bit tricky as the client is in half-connected state
   meaning that the connection is in established state but the
   accept_q in socket queue contains still data which needs to be
   cleared.
4) Client A then disconnects, all data is sent etc

The above was not working correctly as the system did not handle the
step 3) properly. The client B was accepted in the application even
if the connection was closing.

After this commit, the commit called "net: tcp: Accept connections
only in LISTENING state" and related other commits are no longer
needed and are reverted.

83bb911a21 net: openthread: Update OpenThread version
Use the newest version of the OpenThread project, as updated in
https://github.com/zephyrproject-rtos/openthread/pull/2.

Introduce the following fixes along with the update (they're squashed to
retain bisectability of OT samples):

* Update configs and flags used
	Some OT configs were renamed, some new were introduced that Zephyr port
	needs to set.

* Add entropy platform driver
	OpenThreads `random` platform subsystem was replaced with `entropy`
	subsystem which is supposed to serve as an entropy source for the
	generic OpenThread's random generator.

* Halt OT thread when OT command is processed
	OpenThread can currently be processed from two threads - a
	genuine OpenThread thread and shell thread, which processes CLI
	commands. This could cause trouble, when context was switched
	during OT command processing (i.e. switched to process an incomming OT
	message, while still in unfinished command handler).

	In result, it was not possible to turn the commissioner role on via
	CLI, as the commissioner petition response was handled before the
	Commissioner::Start function finished its execution (if the
	petitioner is also the network leader, all messages are passed
	internally within the stack).

	Fix this by suspending the OT thread for the time of an OT command
	processing.

32169886ca drivers: Add video API
This generic video API can be used to capture/output video frames.

Once a video buffer is enqueued to a video device endpoint, device owns
the buffer and can process to capture (camera), output (disk, display),
convert (hw encoder)... User can then call dequeue to retrieve
the processed buffer (video driver ensure cache coherency).

Once dequeued, video buffer is owned by user (e.g. for frame
processing, display buffer update, write to media, etc...).

For each video-buffer, user needs allocate the associated frame buffer
via video_buffer_alloc. Buffer format is defined by video device
endpoint configuration. Video device can be controlled (e.g. contrast,
brightness, flip...) via controls.

8ec765b0bf x86: intel64: set up memory sections
Some linker symbols indicating the bounds of various memory
areas needed for setting up boot MMU regions are now in
place.

MMU_BOOT_REGION macros added to align the bounds of these
sections if we're using runtime page tables.

_image_rodata_start moved to the proper place, it was not
accounting for the rodata sections specified in
linker/common_rom.ld.
