6996d2cc2c k_timer optimization: INVALID_OBJECT can not be returned
As it is impossible for GETTIMER() to return a NULL pointer, task_timer_alloc()
will never return INVALID_OBJECT.

f8619b4181 Refactor _Cget() to invoke _NanoFatalErrorHandler()
It is a fatal error if the microkernel is configured with either too few
command packets or too few timer packets.

NOTE: During this refactoring of _Cget(), not only is it renamed to
_nano_fiber_lifo_get_panic(), but it is moved into "nano_lifo.c".

e2fa00be6e Algorithm improvement for timer based random number generator
The timer based pseudo random number generator returns the
number of system clock ticks. If the random number function is
called subsequently in a time less than a system clock tick, it
leads to getting same number.

To prevent this the counter is introduced. Counter gets changed
each call, so it ensures the caller gets different numbers each time
the random number function gets called.

The in-code Documentation Guidelines contains the best practices for
documenting code using Doxygen. The guidelines offer options for both
novice and expert developers to document their code in a compatible and
correct manner.
Fully marked and simplified templates are provided to ease the
documentation effort.
Examples taken directly from Tiny Mountain's code show the difference
clearly.
The .c files contained here are used for the examples only and do not
have any function within Tiny Mountain.
Finally, the doxygen.rst file was updated to include the new content.
