The ordering of the Python functions loosely matches the corresponding
function in the C header file, but not exactly. As we add more functions
it is easier to track what is missing if they are in the same order.
Move some functions around to achieve this.

The return value is not actually mutable, so it seems more correct to
return bytes rather than a bytearray.

It is annoying to have to add .value when we want the value of a Property.
Make Property a subclass of bytearray so that it can be used directly when
the value is required.
Fix the Property class comment while we are here.

When calling libfdt functions which are not supported by the Fdt class it
is necessary to get direct access to the device tree data. At present this
requries using the internal _fdt member. Add a new method to provide
public access to this, without allowing the data to be changed.
Note that a bytearray type is returned rather than str, since the swig
types are set up for bytearray to map correctly to const void *.

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.

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
