Upcoming memory protection features will be placing some additional
constraints on kernel objects:
- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.
Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.
It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.
There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.
k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.

The worst-case maximum number of CCC entries we need is actually
MAX_CONN + MAX_PAIRED. Provide a helper define for it and use it
whenever appropriate.

This will prepare test cases and samples with metadata and information
that will be consumed by the sanitycheck script which will be changed to

This adds bt_gatt_register_service using bt_gatt_service which contains

in each and every attribute declared.

The state machine of the game assumes that the user needs to
explicitly re-select multiplayer game when disconnected. We need to
therefore make sure that advertising stays off as soon as the first
connection happens.

Occasionally the sound might stay enabled for the restart timeout (2
seconds) if the ball would hit the wall right before missing the
paddle. Ensure that it's disabled whenever the game ends.

The buttons on the microbit cause quite easily "ghost" key presses.
Add a simple filter that ignores button presses from the same button
that happen less than 100ms from each other.

The stuff that the GPIO button callback does (in particular the printk
calls) requires more stack space from the ISR stack. Increase it to 1k

Both the string and image rendering may want to take advantage of
scrolling and sequential display capabilities. Consolidate the APIs so
that there's a single one for images (mb_display_image) and a single
one for strings (mb_display_print). Both take a duration parameter for
the per-frame duration as well as a mode parameter which specifies
sequential vs scrolling behavior as well as an optional looping flag.

Add a new mb_display_print() API which takes printf-style parameters
and outputs scrolling text instead of one character at a time. The
existing mb_display_str() API is renamed to mb_display_string() for
consistency, and now also takes printf-style parameters.

Adds a simple driver to access the 5x5 LED display found on BBC
micro:bit boards. The display is so limited that no effort is done to
try to integrate with the existing console (which would likely make
the display unusable). Instead, dedicated mb_display_* APIs are added
that are specific to this display.
