Python recently deprecated some test methods in favour of others. Adjust
the code to avoid warnings.

This function should use a void * type, not char *. This causes an error:
TypeError: in method 'fdt_property_stub', argument 3 of type 'char const *'
Fix it and update the tests.

Python3 removes support for C-style octal literals, using 0oXXXX instead.
Python2 also supports this form, so move to the new style.

It is useful to be able to create a device tree from scratch using
software. This is supported in libfdt but not currently available in the
Python bindings.
Add a new FdtSw class to handle this, with various methods corresponding
to the libfdt functions. When the tree is complete, calling AsFdt() will
return the completed device-tree object.

At present pack() calls fdt_pack() which may well reduce the size of the
device-tree data. However this does not currently update the size of the
bytearray to take account of any reduction. This means that there may be
unused data at the end of the bytearray and any users of as_bytearray()
will see this extra data.
Fix this by resizing the bytearray after packing.

Extend the Properties class with some functions to read a single integer
property. Add a new getprop_obj() function to return a Property object
instead of the raw data.
This suggested approach can be extended to handle other types, as well as
arrays.

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 *.
