Instead of initializing the stack (when INIT_STACKS is enabled) in start_task()
and _fiber_start(), do it in _NewContext(). This helps to both reduce code
duplication AND ensure that all contexts get an initialized stack (previously
the background/idle task's was missed).

According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build. This patch converts to them to the newer ccflags-y which also
fixes the problem.

Since the address of the new context is known before _NewContext() is invoked
(due to it being passed a properly aligned stack), there is no longer any
need for _NewContext to return the pointer to the context.
Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it
will always match the passed stack pointer.

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".

Renames the include file defining non-public microkernel structures
from k_struct.h to kernel_structures.h, and relocates it to the
microkernel's non-public include file directory. This means that
applications and drivers including the microkernel's public APIs,
using microkernel.h, can no longer access non-public information.
Note: This change also eliminates some redundant #includes by the
microkernel's own subsystems, since the inclusion of minik.h brings
in the vast majority of public and non-public APIs.

without utilizing non-public microkernel API information.
Also adds code to generate a build error if the hard-coded size
is too small, just in case the size of the command packet changes.
(Can't check for size equality, since the structure size may vary
from one compiler to the next. If the value is too large any extra
space in the command packet set will simply go unused.)
