418e3d361b test_lifo: add multiple-waiters scenario
A number of fibers pend on a LIFO, then the task queues data on it, once
for each waiter. Each time, the first fiber in the queue wakes up, is
context-switched to, verifies the data is the one expected, and gives a
semaphore. The task finally must be able to obtain the semaphore an
amount of times equals to the number of fibers.

f84697fd17 nano objects: rename fiber/ISR 'give' routines
Append '_non_preemptible' to _fifo_put, _lifo_put, _sem_give and
_stack_push.

The original names do not convey the fact that these routines are
usable only by fibers and ISRs because they do not invoke a context
switch if they cause a fiber to become ready.

b4484a7816 nano_lifo: allow multiple fibers to pend
The nanokernel LIFOs could only have one fiber pending on one of
them concurrently. If a second fiber wanted to take a contested
LIFO, if would kick the pending fiber out of the wait 'container',
but would not put it in back in the ready queue with an error.  Instead,
it would, for all intents and purposes, remove it from the scheduling
mechanism of the nanokernel: the fiber would be 'lost' at that point.

The nanokernel LIFOs now make use of the fiber pend queue, and thus
allow multiple fibers to pend concurrently.

sysgen is updated since the microkernel initializes statically two
LIFOs, one for the command packets and one for the timer packets, and
the LIFO data structure has changed.

The nano_timers use the LIFOs and look at their internals, so they are
updated as well.

194ad8da3b nano_fifo: use struct _nano_queue and _nano_wait_q routines
Adapt nano_fifo to use the struct _nano_queue and the _nano_wait_q
interface built on it.

The nano_fifo is the first to be adapted to use these since it currently
is the only nanokernel object that can handle multiple waiters, and the
_nano_wait_q abstraction was taken directly from it. This allows an easy
transition and can reuse the same tests to verify the abstraction is
working correctly.

ec87ce02a5 Finish consolidating workload monitoring code
Moves workload monitoring logic from microkernel server file and
relocates it so it resides with other workload monitoring code.
This change means that the various variables use for workload monitor
computations no longer need to be globally visible.

This move also allows correction of two pre-existing issues:

1) Eliminates reference to non-existent POWERSAVEOFF configuration
   option.
2) Test to see if idle task has been deselected is no longer done
   if prior test has shown that it has just been selected, since
   the two conditions are mutually exclusive.

05390a986b Cosmetic changes to _LowTimeInc()
Renames routine to conform with coding conventions and enhances
comments describing routine. Also converts routine to a non-global
routine, since it's only called from one place.

c747690754 Eliminate kernel/microkernel/ticks.c
This file contains content that really belongs in the files that
implement the microkernel's system tick logic and the microkernel's
timer object logic. Once the content is relocated, the file is
empty and can be deleted.

2f9718338e Relocate arch-independent _TaskAbort()
Moves the architecture-independent microkernel's handler for
fatal task errors into the file containing other abort-related
routines, since it doesn't have anything to do with the
microkernel server code it previously resided with.

105477a2e0 Cosmetic changes to microkernel server file
1) Updates comments to better describe the purpose of the file.
2) Corrects an excessively long line.
3) Eliminates an unnecessary #ifdef, which isn't required now that
   the file has been moved to the main microkernel source directory.

df368598cb Rename kernel/nanokernel/microk.c to kernel/microkernel/server.c
Relocates the microkernel server implementation so that it appears
in the intuitive kernel subdirectory, and give it a more meaningful
name.
