[PATCH v3 0/4] Introduce Python bindings for libfdt

[Simon Glass <sjg-F7+t8E8rja9g9hUCZPvPmw@public.gmane.org>]

At present libfdt consists of only a C implementation. Many scripts are
written using Python so it useful to have Python bindings for libfdt.
Apparently this has never been attempted before, or if so I cannot find a
reference.

This series starts the process of adding this support, with just a
bare-bones set of methods, to attract initial comments.

The v3 series makes the binding more pythonic, allowing things like:

    fdt = libfdt.Fdt(open(fname).read())
    node = fdt.path('/subnode@1')
    print node.prop('compatible').data()
    subnode = node.first_subnode_quiet()
    while subnode:
        print subnode.name()
        subnode = subnode.next_subnode_quiet()

There are still some open question, particularly around naming.

Changes in v3:
- Make the library more pythonic
- Add classes for Node and Prop along with methods
- Add an exception class
- Use Python to generate exeptions instead of SWIG

Changes in v2:
- Add exceptions when functions return an error
- Correct Python naming to following PEP8
- Use a class to encapsulate the various methods
- Include fdt.h instead of redefining struct fdt_property
- Use bytearray to avoid the SWIG warning 454
- Add comments
- Update tests for new pylibfdt
- Add a few more tests to increase coverage
- Add some more tests
- Add details on how to obtain full help and code coverage
