ecb21febfd meson: port python bindings to build natively via meson and meson-python
We get full build parallelism and fewer confusing ancient distutils
paths. The python wheels build fully standalone, including linking
libfdt as a static library.

For convenience, when running pip install a meson option is passed that
prevents building tools or installing headers/pkgconfig files.
meson-python would otherwise include them in the wheel itself, in case
they are needed, but this is essentially a bit useless so don't bother.

The old setuptools-based build is now redundant and goes away.

dd1b3e532d meson: support building libfdt without static library
Some packaging systems like NixOS don't support compiling static
libraries. However libfdt's meson.build uses `both_library()` which
forces the build to always compile shared and static libraries. Removing
`both_library()` will make packaging easier.

libfdt uses `both_libraries()` to support the 'static-build' option.
But we do not need the 'static-build' option as Meson can natively
build static using

> meson setup builddir/ -Dc_link_args='-static' --prefer-static --default-library=static

So drop 'static-build' and then replace `both_libraries()` with
`library()`.

bdc5c8793a meson: allow disabling tests
The new meson build system support diverges from former build system
where the tests were not built until required.

This has caused an issue in NixOS[1] due to broken build of tests in
Darwin platform, so this patch allows the control if tests should be
build or not.

7ad60734b1 Allow static building with meson
Added "static-build" option in the meson_options.txt.
Setting it to "true" allows static building.

67849a3279 build-sys: add meson build
The meson build system allows projects to "vendor" dtc easily, thanks to
subproject(). QEMU has recently switched to meson, and adding meson
support to dtc will help to handle the QEMU submodule.

meson rules are arguably simpler to write and maintain than
the hand-crafted/custom Makefile. meson support various backends, and
default build options (including coverage, sanitizer, debug/release
etc, see: https://mesonbuild.com/Builtin-options.html)

Compare to the Makefiles, the same build targets should be built and
installed and the same tests should be run ("meson test" can be provided
extra test arguments for running the equivalent of checkm/checkv).

There is no support EXTRAVERSION/LOCAL_VERSION/CONFIG_LOCALVERSION,
instead the version is simply set with project(), and vcs_tag() is
used for git/dirty version reporting (This is most common and is
hopefully enough. If necessary, configure-time options could be added
for extra versioning.).

libfdt shared library is build following regular naming conventions:
instead of libfdt.so.1 -> libfdt-1.6.0.so (with current build-sys),
libfdt.so.1 -> libfdt.so.1.6.0. I am not sure why the current build
system use an uncommon naming pattern. I also included a libfdt.pc
pkg-config file, as convenience.

Both Linux native build and mingw cross-build pass. CI pass. Tests are
only run on native build.

The current Makefiles are left in-tree, and make/check still work.
Eventually, the Makefiles could be marked as deprecated, to start a
transition period and avoid having to maintain 2 build systems in the
near future.

(run_tests.sh could eventually be replaced by the meson test runner,
which would have several advantages in term of flexibility/features,
but this is left for another day)
