4fe98a46f5 Initialize stack area in _NewContext()
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).

bbe84f8ae5 Use ccflags-y and asflags-y instead of EXTRA_CFLAGS
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.

40b5200c73 Optimizations to _NewContext() and _NewContextInternal()
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.

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".
