Run all Python code through autopep8

Run all Python code through autopep8 as follows:

    autopep8 -ri --ignore=E261,E262,E302 --max-line-length 1000 .

E261 or E262 would cause spaces after a comment's hash sign
to be squashed. Since some of the comments in cppcheck's
Python code have space-indented code examples, not ignoring
E261 or E262 would wreck the formatting of those examples.

E302 prevents autopep8 from adding some blank lines.

setting --max-line-width ensures no line will be wrapped.
