various python neatness cleanups

All changes were created by running

"pyupgrade --py3-only"

and committing the results. Although this has been performed in the
past, newer versions of pyupgrade can automatically catch more
opportunities, notably list comprehensions can use generators instead,
in the following cases:
- unpacking into function arguments as function(*generator)
- unpacking into assignments of the form x, y = generator
- as the argument to some builtin functions such as min/max/sorted

Also catch a few creeping cases of new code added using older styles.
