format: use autopep8

Use autopep8 for coding format, and only for whitespace changes. This
change drops use of tabs in favor of spaces.

Doesn't use autopep8 --aggresive option.

Format command:

$ autopep8 --inline --recursive .

When using git-blame, use --ignore-rev in order to ignore this
reformatting commit.
