Using 'pip' and several setup.py sub-commands currently don't work with
pylibfdt. The primary reason is Python packaging has opinions on the
directory structure of repositories and one of those appears to be the
inability to reference source files outside of setup.py's subtree. This
means a sdist cannot be created with all necessary source components
(i.e. libfdt headers). Moving setup.py to the top-level solves these
problems.
With this change. the following commands now work:
Creating packages for pypi.org:
./setup.py sdist bdist_wheel
Using pip for installs:
pip install .
pip install git+http://github.com/robherring/dtc.git@pypi-v2

The DTC version in version_gen.h causes a warning with setuptools:
setuptools/dist.py:501: UserWarning: The version specified ('1.6.1-g5454474d') \
is an invalid version, this may not work as expected with newer versions of \
setuptools, pip, and PyPI. Please see PEP 440 for more details.
It also creates an unnecessary dependency on the rest of the build
system(s). Switch to use setuptools_scm instead to get the version for
pylibfdt.

With meson, we have to support out-of-tree build.
Introduce a --top-builddir option, which will default to the current
directory to lookup generated filed such as version_gen.h and output
directories.
Other source paths are derived from the location of the setup.py script
in the source tree.
--build-lib is changed to be relative to the current directory, instead
of relative to setup.py. This has less surprising results!

Currently setup.py depends on being invoked from the right directory
(specifically it needs to be run from the root of the project). That's a
bit confusing.
This updates setup.py to no longer depend on the invoking directory by
instead having it change directory to the location of the script itself,
then using internal paths relative to that.

Currently setup.py expects the library version in a VERSION environment
variable, or it exctracts the version from the Makefile. The latter is
for the case where the script is run standalone, rather than from make.
But parsing the Makefile is ugly and fragile, and won't always get the
same version we put into the C code.
This changes to instead extracting the version from the trivial .h file we
already generate to put the version into C code. It's still slightly ugly,
but it's simpler and since we can control the precise format of that .h,
not as fragile.
This lets us remove the remains of the makefile parsing code from setup.py.

This points to the Python setup script, since we reference it in a couple
of places. While we're there correct two small problems:
1) setup.py is part of the checked in sources and so lives in
$(PYLIBFDT_srcdir) not $(PYLIBFDT_objdir) [this only worked because
those are the same by default]
2) The module itself should depend on the setup script so it is rebuilt
if the script is changed

At the moment we have some fiddly code to either pass in make's CPPFLAGS to
setup.py, or have setup.py extract them from the Makefile. But really the
only thing we need from here is the include paths. We already know what
include paths we need (libfdt/) so we can just set that directly in
setup.py.

Currently we build the Python extension module from all the libfdt source
files as well as the swig wrapper file. This is a bit silly, since we've
already compiled libfdt itself.
This changes the build to instead build the extension module from just the
swig wrapper, linking it against the libfdt.a we've already build.

Our Makefile currently passes PYLIBFDT_objdir into setup.py in an attempt
to set the correct place to put the Python extension module output. But
that gets passed in the 'package_dir' map in distutils.
But that's basically not what package_dir controls. What actually makes us
find the module in the right place is the --inplace passed to setup.py
(causing the module to go into the current directory), and the following
'mv' in the Makefile to move it into the right final location.
We can simplify setup.py by dropping the useless objdir stuff, and get the
module put in the right place straight way by instead using the --build-lib
setup.py option.

At present we require that setup.py is executed from the Makefile, which
sets up various important things like the list of files to build and the
version number.
However many installation systems expect to be able to change to the
directory containing setup.py and run it. This allows them to support (for
example) building/installing for multiple Python versions, varying
installation paths, particular C flags, etc.
The problem in implementing this is that we don't want to duplicate the
information in the Makefile. A common solution (so I am told) is to parse
the Makefile to obtain the required information.
Update the setup.py script to read a few Makefiles when it does not see
the required information in its environment. This allows installation
using:
./pylibfdt/setup.py install
