Peter Mitsis 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).

Anas Nashif 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.

Peter Mitsis 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.

Peter Mitsis 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().

Juan Manuel Cruz 808e5c4ba0 Fixes to Kbuild to build on ARM architecture.
This commit fixes issues to allow build on ARM architecture.
- It fixes the include paths in Makefiles.
- It fixes the include path for the offsets.c compilation.
- It fixes the linker command. This changes is needed because gcc
  ARM cross-compiler does not accept an AT() command without
  specifing an address explicitly. This corner case appears
  on ARM architectures when XIP is disabled.

Allan Stephens 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.
