This sample displays the colors red, green, and blue on consecutive
LEDs in an LED strip, moving the starting point where red begins
further down the strip at each time step. The color band wraps around
to the beginning when it reaches the end.
Since this is the first application in samples/drivers to have
documentation, add samples/drivers/drivers.rst as well, and include it
in the top-level toctree from samples/samples.rst.

This patch adds the mpu_stack_guard_test to the available samples.
The purpose of this test is to exercize the thread stack guard enabled
via MPU on arm platforms.

This patch contains a MPU test with a set of options to check
the correct MPU configuration against the following security
issues:
* Read at an address that is reserved in the memory map.
* Write into the boot Flash/ROM.
* Run code located in SRAM.
The MPU test application uses the Zephyr shell.

Docs need a label at the top so we can use :ref:`labelname` to
create a link to that doc from other docs.

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.

This change introduces console_getchar() and console_getline() API
calls which can be used to get pending console input (either one
char or whole line), or block waiting for one. In this regard, they
are similar to well-known ANSI C function getchar/gets/fgets, and
are intended to ease porting of existing applications to Zephyr, and
indeed, these functions (shaped as an external module) are already
used by few applications.
The implementation of the functions is structured as a new "console"
subsystem. The intention is that further generic console code may be
pulled there instead of being in drivers/console/. Besides the
functions themselves, initialization code and sample applications
are included.
At this time, there're may limitations of how these functions can
be used. For example, console_getchar() and console_getline() are
mutually exclusive, and both are incompatible with callback
(push-style) console API (and e.g. with console shell subsystem
which uses this API). Again, the intention is to make a first step
towards refactoring console subsystem to allow more flexible
real-world usage, better reusability and composability.

This will allow inclusion of documentation files that exist outside of
doc/ and will make it possible to add rst files across the tree,
especially for boards, samples and tests.
