By default Renode is searched for in the system PATH.
The PID is stored in renode.pid - the application must be killed with a
signal after a test.
With the XWT gui layer disabled all UART output is directed to the
stdout.

This patch adds a x86_64 architecture and qemu_x86_64 board to Zephyr.
Only the basic architecture support needed to run 64 bit code is
added; no drivers are added, though a low-level console exists and is
wired to printk().
The support is built on top of a "X86 underkernel" layer, which can be
built in isolation as a unit test on a Linux host.
Limitations:
+ Right now the SDK lacks an x86_64 toolchain. The build will fall
back to a host toolchain if it finds no cross compiler defined,
which is tested to work on gcc 8.2.1 right now.
+ No x87/SSE/AVX usage is allowed. This is a stronger limitation than
other architectures where the instructions work from one thread even
if the context switch code doesn't support it. We are passing
-no-sse to prevent gcc from automatically generating SSE
instructions for non-floating-point purposes, which has the side
effect of changing the ABI. Future work to handle the FPU registers
will need to be combined with an "application" ABI distinct from the
kernel one (or just to require USERSPACE).
+ Paging is enabled (it has to be in long mode), but is a 1:1 mapping
of all memory. No MMU/USERSPACE support yet.
+ We are building with -mno-red-zone for stack size reasons, but this
is a valuable optimization. Enabling it requires automatic stack
switching, which requires a TSS, which means it has to happen after
MMU support.
+ The OS runs in 64 bit mode, but for compatibility reasons is
compiled to the 32 bit "X32" ABI. So while the full 64 bit
registers and instruction set are available, C pointers are 32 bits
long and Zephyr is constrained to run in the bottom 4G of memory.

Support using an alternate QEMU path for when we want to use a qemu
version not available in the SDK.
To use the alternate qemu version, export QEMU_BIN_PATH and point it
to the bin directory which contains the qemu executables.
For example:
export QEMU_BIN_PATH=/usr/local/bin

Create a net sample to setup a multi-node RPL mesh network using QMEU.
To enable this, it was necessary implement a hw filter on IEEE 802.15.4
UART Pipe driver and create a QEMU pipe management on cmake.
This sample use a tool developed on zephyr net-tools repository called
virtual-hub.

Instead of accessing the environment variable ZEPHYR_BASE every time we
require accessing the source code root, use an intermediate variable
that has OS path separators correctly set to '/' to avoid issues on
Windows.
Note: This removes the ZEPHYR_SOURCE_DIR CMake variable. External
applications using that will need to change to use the new ZEPHYR_BASE
variable.

I don't know why we have been passing "-serial none" to qemu but it
does not seem to be doing anything useful. So I propose we remove it.
According to the qemu documenation it should be disabling all serial
ports;
"-serial dev
Redirect the virtual serial port to host character device dev. The
default device is vc in graphical mode and stdio in non graphical
mode.
This option can be used several times to simulate up to 4 serial
ports.
Use -serial none to disable all serial ports."
But when we use "-serial none", we always combine it with "-serial
pipe", or "-serial unix", to redirect the serial port, so clearly it
is not disabling all serial ports as it attempting to do.
"-serial none" was first introduced to Zephyr in this commit:
0b54f984b8
As far I can tell, pinging an echo_server works fine without it, so I
suspect that our second -serial flag is overriding it and that it has
no effect.

Using the '\$' technique to accept make variables corrupts Ninja build
systems, so avoid using it when generating Ninja files. Not using it
with Ninja means we need to come up with some other mechanism to
support build-time configuration of the QEMU CLI with Ninja.

Right now we are hardcoded to only qemu, with the native port, we make
this more generic and support this in a plugin mode where a running has
its own cmake definitons implementing the various targets.
