By having this as a Python script rather than a host executable, this
should simplify the build process on non-Unix platforms.
With this change, pyelftools is now required to build Zephyr. Please
consult the getting started documentation for your host platform for
installation instructions.

This patch adds an actual dts target for builds. This required moving the
rules from Kbuild to Makefile and adding the correct dependencies to targets
requiring the dts files.

This patch adds support for using device tree configuration files for
configuring ARM platforms.
In this patch, only the FLASH_SIZE, SRAM_SIZE, NUM_IRQS, and
NUM_IRQ_PRIO_BITS were removed from the Kconfig options. A minimal set
of options were removed so that it would be easier to work through the
plumbing of the build system.
It should be noted that the host system must provide access to the
device tree compiler (DTC). The DTC can usually be installed on host
systems through distribution packages or by downloading and compiling
from https://git.kernel.org/pub/scm/utils/dtc/dtc.git
This patch also requires the Python yaml package.

Rather than having a different set of include paths between offsets.o
and all other objects lets just use ZEPHYRINCLUDE. This removes any
headaches with needing includes from other paths to get offsets.o to
build.

To avoid conflicts with the definition of "FPU" by the external
cmsis sub-system, the symbol "FPU_LEGACY" is now used to denote
the FPU task group. (That is, the group of tasks that utilize
the CPU's floating point registers.)
Backwards compatibility impacts:
* Microkernel applications that define private tasks using the
DEFINE_TASK() macro must now use "FPU_LEGACY" to indicate
that the task is part of the FPU task group, rather than "FPU".
* Applications that perform operations on the members of the
FPU task group must now use "FPU_LEGACY", rather than "FPU".
(Note: There is no apparent reason for an application to
perform such an operation, so this is unlikely to impact
existing applications.)
Backwards compatibility non-impacts:
* Application MDEFs can continue to specify "FPU" when defining
a public task that is part of the FPU task group.
* Applications written for the unified kernel are unaffected,
since the kernel implements task groups differently.

Changes needed to build system to build a unified kernel:
- NUM_COMMAND_PACKETS, NUM_TIMER_PACKETS, NUM_TASK_PRIRITIES must be
passed to sysgen to avoid modifying it. Simply set them to 0. The
unified build does not need them.
- Pass a different kernel type to sysgen if building for a unified
kernel.
- Build kernel_main.c if building an MDEF file (micro/unified).
- The location of the include files for building offsets.h is different
for unified kernels and nano/micro kernels.

Since sysgen copies kernel/microkernel/include/micro_private_types.h and
kernel/microkernel/include/kernel_main.h we need to make sure that
sysgen gets invoked if those files ever change. Otherwise we might have
stale versions.
