The sample application to demonstrate dining philosopher's problem
implementation using CMSIS RTOS V2 APIs with semaphores and mutexes
as resources (forks).
The application makes use of CMSIS_RTOS_V2 APIs on threads, semaphores
and mutexes.

Using multi-queue scheduler doesn't work for cmsis_rtos_v2 as it
supports a max of only 32 priority levels which is less than the
total priority levels required by cmsis_rtos_v2 (which is 56).
Hence explicitly asking the tests to use the scalable scheduler.

Buffer sizes aren't required to be power of 2 for a while. Describe
that by setting buffers sizes to 0, one can get non interrupt driven
operation.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Let's have more orthogonal and cleaner API, where buffers are
configured by tty_set_rx_buf/tty_set_tx_buf, and only them. It
means that newly initialized tty starts in unbuffered mode, which
is somewhat a sidestep from a main usecase behind tty, which is
buffered operation, but again, having a cleaner API (and good
docs, explaining users how it should be and what they should do)
prevails.

The whole "tty" concept is conceived around efficient
interrupt-driven operation. However, it's beneficial to add
non interupt-driven operation under the same API:
1. Wider usecase coverage in general.
2. Allows to use the same familiar API (based on POSIX concepts)
even for UART implementations without interrupt support.
3. Allows to switch operation dynamically based on the needs.
For example, if the system is in degraded mode and interrupt
handling cannot be trusted/disabled, allows to still output
diagnostic information to user. This was the original motivation
to provide such a mode, to support logging subsystem's "panic"
mode.
To implement this feature, tty_set_rx_buf() and tty_set_tx_buf()
functions are provided, allowing to reconfigure buffers used
dynamically. If configured buffer length is 0, the operation
switched to unbuffered.

* Document and add CMAKE_SYSTEM_VERSION
* Document CMAKE_SYSTEM_NAME
* Document CMAKE_SYSTEM_PROCESSOR
* Document BUILD_SHARED_LIBS

CMAKE_SYSTEM_VERSION is required officially by CMake, but appears

nRF 16MHz clock is used by both BLE radio and temperature sensor.
During BLE connection if the temperature sensor is also used then
at some point assert condition is hit in temp_nrf5_sample_fetch().
The error code -EBUSY seen during clock_control_off() is that clock
is no longer needed for the temperature sensor, but it cannot be
just turned off because it is still needed for BLE connection.

ieee802154_nrf5 uses net_analyze_stack function in a loop, which
prints logs at inf level. As net_core's log level is used in
this function which by default is set to inf, it kept spamming stack
usage logs.
Prevent this behavior by adding additional log level check in the driver
itself, so that this log will only be printed if
IEEE802154_DRIVER_LOG_LEVEL is set to debug.
