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.

Introduce TC_RESULT_TO_STR to convert from an integer test result to a
string like "PASS", "FAIL", "SKIP". Do this to remove the defines of
PASS/FAIL/SKIP since those names might get used by other code and to
have a single consistent way of doing the conversion.

To avoid indeterministic behaviour of the tests
which leads to changing coverage reports, let's
finish the tests exectuion as soon as they pass
or fail.
Also let's return 0 to the shell if the test passed,
and 1 if it failed.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

To customise test builds and support test related features such as time
stamps and a boot banner, introduce a Makefile variant that is dedicated
to testing.
Initially we introduce a new config overlay that is used for all tests, in
this case we enable BOOT_BANNER and BUILD_TIMESTAMP. This will print the
current version and the date, useful when reporting bugs and also an
indicator that the system has booted before the test has started.
For example:
[QEMU] CPU: qemu32
***** BOOTING ZEPHYR OS v1.6.99 - BUILD: Dec 21 2016 19:57:13 *****
tc_start() - Test Nanokernel CPU and thread routines

This moves the shell component into its own subsys and groups all
related files and options into a single place.
Additionally, one Kconfig option will now be required to enable the
shell:
CONFIG_CONSOLE_SHELL=y
The header files was also moved to include/shell/shell.h and can be now
referenced with
#include <shell/shell.h>
instead of
#include <misc/shell.h>
Updated documentation as well.

Calling TC_END_REPORT(complex_expression) might have side effects when
complex_expression is later put inside (result == TC_PASS? A : B)
evaluation, because result will be replaced verbatim.
To avoid operator assignment order changing things, protect
replacement of result by adding parenthesis.

This framework makes testing in most parts a lot easier, since it gives
an unified base to work with, removing a lot of unnecessary code from
tests. This framework currently features simple assertions and basic
mocking support. The framework works both with and without Zephyr
running, so it can be used for real unit testing.

printk() is too simplistic and does not handle byte precision on formats
like %02x etc... printf does, so letting the possibility to use it when
relevant. This might be useful when dumping out some network packets,
byte by byte where a precision of 1 byte (thus 2 0's) is necessary.
It's better to have this output:
41 d8 ...
instead of:
