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.

State that a task 'giving' an object to a waiting fiber will be
preempted immediately. Remove useless _Swap() comments.

The nanokernel semaphores could only have one fiber pending on one of
them concurrently. If a second fiber wanted to take a contested
semaphore, 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 semaphores now make use of the fiber pend queue, and thus
allow multiple fibers to pend concurrently.

The 'channel' wording was misleading.

Moves all files in this sub-directory up one level, to the main
nanokernel source directory, then deletes the sub-directory itself.
This change means that all nanokernel source files (with the
excecption of its include files) are now in the main nanokernel
source directory, which is a more intuitive arrangement.
