Add a generic host command handler framework that allows users to
declare new host command handlers with the HOST_COMMAND_HANDLER macro
at build time. The framework will handle incoming messages from the
host command peripheral device and forwards the incoming data to the
appropriate host command handler, which is looked up by id.
The framework will also send the response from the handler back to the
host command peripheral device. The device handles sending the data on
the physical bus.
This type of host command communication is typically done on an embedded
controller for a notebook or computer. The host would be the main
application processor (aka AP, CPU, SoC).

Create a header file and implementation for emulators. Set up a linker
list so that emulators can be found and initialised at start-up.
Emulators are used to emulate hardware devices, to support testing of
various subsystems. For example, it is possible to write an emulator
for an I2C compass such that it appears on the I2C bus and can be used
just like a real hardware device.
Emulators often implement special features for testing. For example a
compass may support returning bogus data if the I2C bus speed is too
high, or may return invalid measurements if calibration has not yet
been completed. This allows for testing that high-level code can
handle these situations correctly. Test coverage can therefore
approach 100% if all failure conditions are emulated.

For iterable areas defined with Z_STRUCT_SECTION_ITERABLE(),
the corresponding output section in the linker script is just
boilerplate. Add macros to make these definitions simpler.
Unfortunately, we have a fair number of iterable sections not
defined with Z_STRUCT_SECTION_ITERABLE(), this patch does not
address this.
The output sections are all named <struct name>_area, update
sanitylib.py with this.
sys_sem with no userspace, and k_lifo/k_fifo are special cases
where different data types that are all equivalent need to be
put in the same iterable area. Add
Z_STRUCT_SECTION_ITERABLE_ALTERNATE() for this special case.

When the device driver model got introduced, there were no concept of
SYS_INIT() which can be seen as software service. These were introduced
afterwards and reusing the device infrastructure for simplicity.
However, it meant to allocate a bit too much for something that only
required an initialization function to be called at right time.
Thus refactoring the devices structures relevantly:
- introducing struct init_entry which is a generic init end-point
- struct deviceconfig is removed and struct device owns everything now.
- SYS_INIT() generates only a struct init_entry via calling
INIT_ENTRY_DEFINE()
- DEVICE_AND_API_INIT() generates a struct device and calls
INIT_ENTRY_DEFINE()
- init objects sections are in ROM
- device objects sections are in RAM (but will end up in ROM once they
will be 'constified')
It also generate a tiny memory gain on both ROM and RAM, which is nice.
Perhaps kernel/device.c could be renamed to something more relevant.

This commit cleans up the section name definitions in the linker
sections header file (`include/linker/sections.h`) to have the uniform
format of `_(SECTION)_SECTION_NAME`.
In addition, the scope of the short section reference aliases (e.g.
`TEXT`, `DATA`, `BSS`) are now limited to the ASM code, as they are
currently used (and intended to be used) only by the ASM code to
specify the target section for functions and variables, and these short
names can cause name conflicts with the symbols used in the C code.

sw_isr_table has two entries, an argument and an ISR function. The
comment on struct _isr_table_entry in include/sw_isr_table.h says that
"This allows a table entry to be loaded [...] with one ldmia
instruction, on ARM [...]". Some arch, e.g. SPARC, also has a double
word load instruction, "ldd", but the instruct must have address align
to double word or 8 bytes.

Updated the bluetooth module to use static handlers. Removed the
old bt specific static registration.
The routine bt_settings_init() is still calling settings_init() which
IMO is not needed anymore.
Updates:
changed SETTINGS_REGISTER_STATIC() to SETTINGS_STATIC_HANDLER_DEFINE()
changed settings_handler_stat type to settings_handler_static type
removed NULL declarations
renamed bt_handler to bt_settingshandler, as bt_handler already exists.
renamed all bt_XXX_handler to bt_xxx_settingshandler to avoid any
overlap.
changed SETTINGS_STATIC_HANDLER_DEFINE() to create variable names from
_hname by just prepending them with settings_handler_.

Add the possibility to register handles to ROM using a new macro
SETTINGS_REGISTER_STATIC(handler), the handler is of type
settings_handler_stat and has to be declared as const:
```
const struct settings_handler_stat test_handler = {
.name = "test", /* this can also be "ps/data"
.h_get = get,
.h_set = set,
.h_commit = NULL, /* NULL defines can be ommited */
.h_export = NULL /* NULL defines can be ommited */
};
SETTINGS_REGISTER_STATIC(test_handler);
```
To maintain support for handlers stored in RAM (dynamic handlers)
`CONFIG_SETTINGS_DYNAMIC_HANDLERS`must be enabled, which is by default.
When registering static handlers there is no check if this handler has
been registered earlier, the latest registered static handler will be
considered valid for any set/get routine, while the commit and export
routines will be executed for both registered handlers.
When a dynamic handler is registered a check is done to see if there was
an earlier registration of the name as a static or dynamic handler
registration will fail.
To get to the lowest possible RAM usage it is advised to set
`CONFIG_SETTINGS_DYNAMIC_HANDLERS=n`.
Updates:
a. Changed usage of RAM to DYNAMIC/dynamic, ROM to STATIC/static
b. Updated settings.h to remove added #if defined()
c. Make static handlers always enabled
d. Corrected error introduced in common-rom.ld.
e. Changed return value of settings_parse_and_lookup to
settings_handler_stat type to reduce stack usage.
f. Updated the name generated to store a handler item in ROM. It now
uses the name used to register in combination with the line where
SETTINGS_REGISTER_STATIC() is called.
g. renamed settings_handler_stat type to settings_handler_static
h. renamed SETTINGS_REGISTER_STATIC to SETTINGS_STATIC_HANDLER_DEFINE()

This convenience macro wraps Z_DECL_ALIGN() and __in_section() to
simplify static definitions of structure instances gathered in dedicated
sections. Most of the time those go together, and the section name is
already closely related to the struct type, so abstracting things behind
a simpler interface reduces probability of mistakes and makes the code
clearer. A few input section names have been adjusted accordingly.

graphic dot matrix displays and electrophoretic displays.
These displays are mostly monochrome and can only display
black and some other color, for example white. Typically,
a byte controls 8 pixels, arranged vertically or horizontally
depending on the controller or settings.
The API is not suitable to display graphics, the purpose is
to display text or symbols. It is possible to use several fonts.
A font can also consist of graphic symbols only and thus,

It's possible to declare static threads that start up as K_USER,
but these threads can't do much since they start with permissions on
no kernel objects other than their own thread object.
Rather than do some run-time synchronization to have some other thread
grant the necessary permissions, we introduce macros
to conveniently assign object permissions to these threads when they
are brought up at boot by the kernel. The tables generated here
are constant and live in ROM when possible.
Example usage:
K_THREAD_DEFINE(my_thread, STACK_SIZE, my_thread_entry,
NULL, NULL, NULL, 0, K_USER, K_NO_WAIT);
K_THREAD_ACCESS_GRANT(my_thread, &my_sem, &my_mutex, &my_pipe);
