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.

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.

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

At present we manually move _libfdt.so into the correct place. Provide a
package directory so we can avoid needing to do this.

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.
