The Zephyr RTOS shall provide a kernel object that implements a traditional first in, first out (FIFO) queue, allowing threads and ISRs to add and remove a limited number of 32-bit data values.

USER_STORY:

As a Zephyr RTOS user I want to be able to exchange 1 to N data objects between different threads and ISR in a thread-safe manner with a first-in-first-out (queue) behaviour.
