47b49a05eafddcaef373f70436d794e9f9f7495c contrib: Fix SyntaxWarning in Python base58 implementation (Alex Willmer)
Pull request description:
In Python integers should be compared for equality (`i == j`), not identity (`i is j`). Recent versions of CPython 3.x emit a SyntaxWarning when they encounter this incorrect usage, e.g.
```
$ python3 base58.py
base58.py:110: SyntaxWarning: "is" with a literal. Did you mean "=="?
assert get_bcaddress_version('15VjRaDX9zpbA8LVnbrCAFzrVzN7ixHNsC') is 0
Tests passed
```

f020aca297 Minor Python cleanups to make flake8 pass with the new rules enabled (practicalswift)
Pull request description:
Enabled rules:
```
* E242: tab after ','
* E266: too many leading '#' for block comment
* E401: multiple imports on one line
* E402: module level import not at top of file
* E701: multiple statements on one line (colon)
* E901: SyntaxError: invalid syntax
* E902: TokenError: EOF in multi-line string
* F821: undefined name 'Foo'
* W293: blank line contains whitespace
* W606: 'async' and 'await' are reserved keywords starting with Python 3.7
```
Note to reviewers:
* In general we don't allow whitespace cleanups to existing code, but in order to allow for enabling Travis checking for these rules a few smaller whitespace cleanups had to made as part of this PR.
* Use [this `?w=1` link](https://github.com/bitcoin/bitcoin/pull/12987/files?w=1) to show a diff without whitespace changes.

* Merge #11881: Remove Python2 support
1874058 Make base58 python contrib code work with python3 (Evan Klitzke)
bc6fdf2 Change all python files to use Python3 (John Newbery)
Pull request description:
Following discussion here: https://github.com/bitcoin/bitcoin/pull/11843#issuecomment-351033742
It's easier for maintainers if all python tools/scripts support only a single version of Python. There are only a few scripts that aren't explicitly python3 at this point, so this PR changes those remaining scripts to explicitly require python3.
