"Modernize" to Python 3.6 via tool

$ pyupgrade --py36-plus $(<filelist)

Here's mostly what it's done:

- No more 'stringliteral'.encode('utf-8'): now b'stringliteral'
- No more unicode literals
- the default open mode is 'r', leaves out if default
- some f-string conversions (if shorter)
- catch OSError instead of subclasses
- no more mention of "object"
- generator expression instead of list comp. when safe
- a few tests had a shebang but actually began with blank line
- remove coding: utf-8  comment, per pep 3120 this is the default now

Manually - if a file in test/ was modified, then did the copyright
header conversion.
