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.

bff7fc17fe Begin consolidation of arch-independent private nanokernel APIs
Introduces nano_internal.h, which will declare all architecture-
independent non-public nanokernel APIs. This file is automatically
incorporated by the various architecture-specific include files
for non-public nanokernel APIs, and will not normally be included
directly by any other files.

a1bd59de35 Eliminate obsolete coding convention comments
Gets rid of single-line comments required by a previous set of
coding conventions. These comments provide no value to readers
and just clutter things up.

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).

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.

a45f691d12 Remove runtime stack alignment from _NewContext()
Runtime alignment of a context's stack is no longer necessary in _NewContext()
as the memory is aligned (via the __stack tag) before calling _NewContext().

ad74658009 Add __stack tag for aligning task/fiber stacks
The "__stack" tag is to be used to align an array (to STACK_ALIGN) for stack
use by either a fiber or task.

86ebbf406c Remove comment listing callers of _NewContext()
There is little value in listing the callers of _NewContext() in its function
header.  Not only was the (deleted) list both incomplete and wrong, keeping
it around and properly updated requires error prone maintenance.

d216a00adc Clean up private APIs that mark context as (non)essential
1) Renames APIs to align them with conventions used by other
   general-context nanokernel APIs.

2) Relocates implementation of these APIs to the architecture-
   independent portion of the nanokernel.

a02396098d Eliminate exposure of non-public microkernel structures
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.
