This driver is a very simple UART driver that can be used to implement
a protocol in application. It has no protocol logic and just allow
application to receive and send data over UART in platform independent
manner.
API is designed to minimize number of required memory copies.
Application is able to provide new buffer every time it decides to
consume received data. It is also able to just alter offset and
reuse current buffer eg if data was corrupted or otherwise invalid.

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.

1) Renames routine to conform to kernel naming conventions.
2) Relocates routine declaration to include files for
non-public nanokernel APIs.
3) Relocates routine definition so that it resides with the
nanokernel's other fiber manipulation routines.
4) Eliminates an unnecessary argument to the routine.

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).

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.

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.

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().

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.

configurations for x86 and arm architecture and the standard
configurations for the following BSPs for microkernel and
nanokernel:
- x86 generic pc
- x86 quark
- arm fsl_frdm_k64f
- arm ti_lm3s6965
They can be applied using the make target defconfig.
This target will generate the corresponding .config
file that will be consumed by the build system.
