17cd196632 Bluetooth: Increase BT_BUF_USER_DATA_MIN to 8
Commit b65fe62719 updated the minimum
required net_buf user data to 8 bytes, so increase this define as
well. It has no other practical purpose except to trigger build
asserts if the user data is for some reason ever decreased below this
minimum.

36edf92ca8 subsys/settings: change processing to const char
The settings module processes the variable name by splitting it up in
a set of variables. This PR removes the splitting up and keeps the
variable name as one string.

It is an alternative to #16609

The possibility is introduced to register handler including a
separator, or to register a handler for each variable.

The ability is introduced to load a subtree from flash or even to load
a single item.

Two ways to operate on variable and settings_handler names are provided:

settings_name_steq(const char *name, const char *key, const char **next)
which checks if name starts with key, returns 1/0 if it does/does not
the remaining part of name is in next.

settings_name_split(const char *name, char *argv, const char **next)
which splits up name in a part before "/"" that is found in argv and
the remaining part that is in next.

A mutex is added to make settings thread-safe

The settings_handlers list is stored in reverse alphabetical order, this
allows registration of e.g. bt and bt/mesh in separate handlers, the bt
handler itself should not contain any handling of bt/mesh.

A settings_deregister() method is added. Settings_handlers can now be
added/removed when required. This saves RAM when settings_handlers are
not needed.

Tests have been updated to reflect changes in the settings api.

Updates after meeting:
1. Removed settings_deregister

2. Changed settings_name_split() in settings_name_next:

int settings_name_next(const char *name, const char **next): returns
the number of characters before the first separator. This can then be
used to read the correct number of characters from name using strncpy
for processing.

3. New functional test added

Update in settings.h: settings_name_next() changed position -> index

Added some comments in settings.h (settings_name_steq())

Updated tests to reflect change to settings_name_next() and pointer
value comparison. The functional test can now also run on qemu_x86.

Corrected some documentation in header.

Changed registration of handlers to be non ordered.

Changed handler lookup to handle non ordered list of handlers, this
improves handler matching in case different length names are compared
and also makes it easier to add rom based handlers as they will not be
ordered.

9d11900dc3 usb: enforce byte alignment on USB records
As seen previously, some toolchain are willing to insert padding

4396dc9c71 Bluetooth: Simplify bt_gatt_notify_cb() API
This API had several issues:

 - The parameter types and order were inconsistent with e.g.
   bt_le_adv_start()
 - There were no real users of num_params, which just caused increased
   code size and memory consumption for no good reason.
 - The error handling policy was arbitrary: if one of the
   notifications would fail it would be impossible for the caller to
   know if some notifications succeeded, i.e. at what point the
   failure happened. Some callers might also want to make note of the
   failure but continue trying to notify for the remaining parameters.

The first issue is easily fixable, but because of the other two I
think it's best we don't have this code as part of the stack, rather
require whoever needs it to do the for loop themselves. It's just a
few lines of code, so the benefit of having this in the stack was
anyway quite minimal.

3d51f7c266 k_stack: make it 64-bit compatible
The k_stack data type cannot be u32_t on a 64-bit system as it is
often used to store pointers. Let's define a dedicated type for stack
data values, namely stack_data_t, which can be adjusted accordingly.
For now it is defined to uintptr_t which is the integer type large
enough to hold a pointer, meaning it is equivalent to u32_t on 32-bit
systems and u64_t on 64-bit systems.

The INT_TO_POINTER and POINTER_TO_INT macros must accommodate larger
pointers on 64-bit systems that don't fit into an int.

In the INT_TO_POINTER case, we have to use an extra cast to intptr_t

7daa5451cf DEVICE_DEFINE(): properly align struct device instances
The DEVICE_DEFINE() macro creates instances of struct device that are
gathered into a contiguous list by the linker. However, some assemblers
pad sections to the next 16-byte boundary or so by default, screwing up
the list walk in z_sys_device_do_config_level(). This is especially
true for 64-bit compilation where sizeof(struct device) isn't a
multiple of 16.

Enforcing an alignment at the linker level would solve this issue when
instances of struct device are gathered from different object files.
However it doesn't solve it when multiple instances are created within
the same object file where the first instance still has a gap with the
next instance, as the assembler does add padding upon section switch
even though the object file ends up with a single section with both
instances. In that case the linker would get rid of the trailing padding
only, leaving the inner gaps between instances in place.

The actual fix is to provide an explicit alignment attribute to the
section for every instances, using __alignof(struct device) which is
the alignment expected by the compiler for that structure.

This also means that the x86_64 workaround in the struct device
definition may go as the "edge case" it refers to is now properly
handled.

follow in the list would be misaligned and get corrupted too.
