Device drivers need to be treated like other kernel objects, with
thread-level permissions and validation of struct device pointers passed
in from userspace when making API calls.
However it's not sufficient to identify an object as a driver, we need
to know what subsystem it belongs to (if any) so that userspace cannot,
for example, make Ethernet driver API calls using a UART driver object.
Upon encountering a variable representing a device struct, we look at
the value of its driver_api member. If that corresponds to an instance
of a driver API struct belonging to a known subsystem, the proper
K_OBJ_DRIVER_* enumeration type will be associated with this device in
the generated gperf table.
If there is no API struct or it doesn't correspond to a known subsystem,
the device is omitted from the table; it's presumably used internally
by the kernel or is a singleton with specific APIs for it that do not
take a struct device parameter.
The list of kobjects and subsystems in the script is simplified since
the enumeration type name is strongly derived from the name of the data
structure.
A device object is marked as initialized after its init function has
been run at boot.

To define a system call, it's now sufficient to simply tag the inline
prototype with "__syscall" or "__syscall_inline" and include a special
generated header at the end of the header file.
The system call dispatch table and enumeration of system call IDs is now
automatically generated.

The doxygen/sphinx/breathe processing for API documentation has some
known issues and we've been using a post-processing filter to eliminate
"expected" warnings. Sphinx/Breathe 5.0 was updated to support
identifying attributes causing these warnings, so this PR adds a
starting list to get around warnings recently introduced with __syscall
and __syscall_inline (PR #4103).

Issuing HCI reset command while having connections sometimes
hung the controller.
ll_reset supplied invalid stop ticker id to role_disable
when trying to stop all connections. Connection role does
not utilize stop ticker. The invalid ticker id supplied
referenced memory outside the pool of tickers and based on
what the content is in RAM there, the controller would hang
trying to stop connections.
Fixed by not calling the ticker_stop interface with invalid
ticker ids.

A previous patch which moved dispatching the health publish callback
to a later moment introduced a regression where the period divider
does not get updated when it should. In fact, having the divider as
part of the Health Server context is redundant, since the same
information is already stored generically in the model publication
context. Switching to using the model publication context makes things
simpler and ensures that the value is always up-to-date.
With this patch it is possible to pass MESH/SR/HM/CFS/BV-02-C.

- syscall.h now contains those APIs needed to support invoking calls
from user code. Some stuff moved out of main kernel.h.
- syscall_handler.h now contains directives useful for implementing
system call handler functions. This header is not pulled in by
kernel.h and is intended to be used by C files implementing kernel
system calls and driver subsystem APIs.
- syscall_list.h now contains the #defines for system call IDs. This
list is expected to grow quite large so it is put in its own header.
This is now an enumerated type instead of defines to make things
easier as we introduce system calls over the new few months. In the
fullness of time when we desire to have a fixed userspace/kernel ABI,
this can always be converted to defines.
Some new code added:
- _SYSCALL_MEMORY() macro added to check memory regions passed up from
userspace in handler functions
- _syscall_invoke{7...10}() inline functions declare for invoking system
calls with more than 6 arguments. 10 was chosen as the limit as that
corresponds to the largest arg list we currently have
which is for k_thread_create()
Other changes
- auto-generated K_SYSCALL_DECLARE* macros documented
- _k_syscall_table in userspace.c is not a placeholder. There's no
strong need to generate it and doing so would require the introduction
of a third build phase.

This header could be maintained by hand since there are no inputs

clear.
