Allan Stephens c29d41cab7 Rename nanokernel's nanok.h to nano_private.h
The new name better reflects that this file contains all private
nanokernel APIs that are used by various kernel subsystems.

Benjamin Walsh 3f671dc68c nano_sema: add timeouts support
Add the _timeout() variants to the _take_wait() routines. Those allow
waiting with a timeout. The return values are the same as for the
regular _take() routines: 1 for success, 0 for failure.

Note that the task_ variant is still polling, and the task is not put on
a timeout queue, instead polling for the ticker change in addition to a
semaphore state change.

Allan Stephens 5189844df5 Eliminate VxMicro branding in kernel code
Eliminates references to the obsolete OS name. In most cases the
name is simply removed, as it isn't necessary.

Benjamin Walsh 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.

Benjamin Walsh 63a85d1eb7 nano objects: clarify 'fibers preempting tasks' comments
State that a task 'giving' an object to a waiting fiber will be
preempted immediately. Remove useless _Swap() comments.

Benjamin Walsh 7a7ba579c5 nano_sem: allow multiple fibers to pend
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.

Allan Stephens 661ba14943 Eliminate nanokernel/core sub-directory
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.
