The pylibfdt code is written for Python2, not Python3. So, it's safer to
explicitly request Python2 in our scripts and when checking pkg-config.
On Arch Linux at least, there isn't actually a plain "python" link, just
"python2" and "python3", so the current setup won't work at all.
According to https://www.python.org/dev/peps/pep-0394/ using "python2"
should work, and is preferred.
Updating pylibfdt to work with Python3 would be nice, but is a problem for
another day.

Some types used by libfdt.h are not understood the Python module since
they are defined outside it. An example is an attempt to do this:
import libfdt
result = libfdt.fdt_node_offset_by_phandle(fdt, phandle)
This results in:
TypeError: in method 'fdt_node_offset_by_phandle', argument 2 of
type 'uint32_t'
Include the standard integer header file to fix this.

Since we are using the standard .i extension for the swig file, we can use
setup.py to build the wrapper. Drop the existing build code since it is
not needed.

The current mechanism uses a shell construct, but it seems better to use
a Makefile approach.

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

We should follow PEP8 even for our setup() call.

The .i extension allows Python distutils to automatically handle the swig
file. Rename it.

This is in a separate patch since I not sure if GNU make features
are permitted in the Makefile.

Use the same version number in the module as with the rest of libfdt. This
can be examined with:
import pkg_resources
print pkg_resources.require('libfdt')[0].version

Adjust the setup script to support installation, and call it from the
Makefile if enabled. It will be disabled if we were unable to build the
module (e.g. due to swig being missing), or the NO_PYTHON environment
variable is set.

At present we manually move _libfdt.so into the correct place. Provide a

At present setup.py adjusts its command line when running, so that the
C flags and file list can be passed as arguments. Pass them in environment
variables instead, so we can avoid this messiness. It also allows us to
support the 'install' command.

Add Python bindings for a bare-bones set of libfdt functions. These allow
navigating the tree and reading node names and properties.
