79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

5113c1418d subsystems: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

f1e75dea50 bluetooth: ots: notify application prior to object name change
This change augments the application object name change notification to
occur prior to the actual name change done by the OTS layer.

Notifying prior to the actual name change makes it possible to inform the
application of the current name of the object as well as the new name.

3a03d9c50d bluetooth: ots: reduce directory listing memory usage
Allocating a buffer to hold the entire directory listing consumes a very
large sum of memory when a large number of OTS objects are supported.

This implementation minimizes the memory footprint of the directory
listing by only allocating the minimum necessary buffer size to allow
for efficient over the air transfer. The contents of the transferred
buffer are built incrementally and upon request.

The directory listing manipulation upon object creation and deletion can
be removed since the directory listing content is never constructed
until it is requested.

d6314fa456 bluetooth: ots: Add object name write capability
Add the ability to perform a write on the object name GATT
Characteristic with a notification callback to the application
that the name has been written.

In order for this operation to work the memory backing the
object name must be modifiable. To prevent forcing the user
to always allocate 120 bytes for the name, the maximum name
length is changed from a define to a configuration parameter.

cfe0849072 Bluetooth: services: Adds OTS name length checks
Adds name length checks. The OTS spec does not
explicitely specifiy a maximum name length, but the
maximum name length in the directory listing object
shall be less or equal to 120 octets.

22068d4967 Bluetooth: services: Do not set current object until selected
Do not make the first object added to the object transfer server the
current (=selected object).  This leads to the server having no
current object until one is selected by the client.

This solves a startup issue where the selected callback is not called
by the server if the first object selected by the client happens to be
the same object as the object that was first added to the server.  In
that case, the user of the OTS does not know which object is selected,
and therefore may not be able to supply the correct data later.

e90ec2df44 Bluetooth: services: Adds directory listing object to OTS
The directory listing object is an internal object which
content is the aggregation of all the metadata of all objects
(including the directory listing object itself). The client
can read this value to get a list of all objects with names,
lengths, and other metadata.
