size_report was using the environment variables NM and OBJDUMP to find
it's toolchain dependencies. It is not clear how well this will work
on different platforms; OSX, Windows. So we now pass the paths of
these dependencies from the build system to the script.
PS: This ensures that size_report uses the cross-compiler's GNU bin
tool instead of the host GNU bin tools. This is presumably beneficial
as it has been required for other GNU bin tools like GDB.

It is supported to add give extra flags to the linker from the
commandline like this:
cmake -DEXTRA_LDFLAGS=-Lmy_dir path
But unfortunately this was broken during the CMake
migration. Interestingly, the reason that it was broken is that KBuild
was also partially broken. KBuild would pass on EXTRA_LDFLAGS when
object files were linked together into built-in.o files, but it would
not use EXTRA_LDFLAGS for the final link into an elf file.
This patch fixes EXTRA_LDFLAGS.

This commit fixes
https://github.com/zephyrproject-rtos/zephyr/issues/5008.
It does so by splitting up gen_syscalls.py into two scripts with a
json metadata file to communicate syscall metadata between them. The
parsing script parses header files from include/ and writes syscall
metadata to a file if the contents changed. The generation script
reads from the json file and generates syscall code.
The build system DAG now looks like this:
always_rebuild -> json -> syscalls -> offset.o
The script for generating json will do so only if the content changes,
this ensures that the entire DAG does not always do a full rebuild.

The core kernel is built with the --no-whole-archive linker option.
For all the individual .o files which make up the kernel, if there
are no external references to symbols within these object files,
everything in the object file is dropped.
This has a subtle interaction with system call handlers. If an object
file has system call handlers inside it, and nothing else in the
object file is referenced, then the linker will prefer the weak
version of the handler in the generated syscall_dispatch.c. The
user will get an "unimplemented system call" error if the associated
system call for that handler is made.
Fix this by making a fake reference to the handler function at the
system call site. The address gets stored inside a special section
"hndlr_ref". This is enough to prevent the handlers from being
dropped, and the hndlr_ref section is itself dropped from the binary
from gc-sections; these references will not consume space.
Handlers for system calls that are never invoked anywhere will still be
dropped if nothing else in their containing C files is used, which is
a good thing. A future enhancement could be to split out all handlers
into individual object files, such that we can guarantee that any system
call that is not made somewhere in the application will have its handler
dropped. This will need to be extended to driver subsystems as well.
This won't be pretty but will ensure the tightest binary size.
Fixes#5184.

According to yaml syntaxic rules, 'properties' described in dts
bindings yaml files could be seen as 'mapping'(key/value couple),
instead of 'series' (list of single elements).
yaml 'mappings' will then be converted by yaml python library as
python 'dict' which will ease treatment (instead of current list
as were before this commit).
Same treatment is applied to 'inherits'.
script extract_dts_inlcude is updated to take change of yaml_list
structre into account. This allows some code simplification. Largest
impact is yaml_collapse function which works now allow complete
overload method on all the attributes of a yaml nodes.

sanitycheck was incorrectly documenting that --extra-args would pass
on it's input unchanged to Make.
In reality --extra-args acts as a way to define extra CMake cache
entries. The key-value entries will be prefixed with -D before being
passed to CMake.
E.g
"sanitycheck -x=USE_CCACHE=0"
will translate to
"cmake -DUSE_CCACHE=0"

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

The port will enable Zephyr to run as a guest OS on x86-64 systems. It
comes with a test on QEMU to validate that, thus this new board
introduction. It's "make run" target will issue QEMU with the same
configuration Jailhouse upstream uses for their confis/qemu-x86.c root
cell configuration:
Test configuration for QEMU Q35 VM, 1 GB RAM, 4 cores,
6 MB hypervisor, 60 MB inmates (-4K shared mem device)
This will work provided qemu-system-x86_64 is installed in the system
and a given (qcow2) image with the Jailhouse root cell in it is
provided (any of those will ever ship with Zephyr, it's out of its
scope).

Kernel object metadata had an extra data field added recently to
store bounds for stack objects. Use this data field to assign
IDs to thread objects at build time. This has numerous advantages:
* Threads can be granted permissions on kernel objects before the
thread is initialized. Previously, it was necessary to call
k_thread_create() with a K_FOREVER delay, assign permissions, then
start the thread. Permissions are still completely cleared when
a thread exits.
* No need for runtime logic to manage thread IDs
* Build error if CONFIG_MAX_THREAD_BYTES is set too low
