Jun Wu 3e0b781197 py3: only use binary stdin/stdout/stderr
Summary:
Drop stdoutbytes/stdinbytes. They make things unnecessarily complicated
(especially for chg / Rust dispatch entry point).

The new idea is IO are using bytes. Text are written in utf-8 (Python 3) or
local encoding (Python 2). To make stdout behave reasonably on systems not
using utf-8 locale (ex. Windows), we might add a Rust binding to Rust's stdout,
which does the right thing:
- When writing to stdout console, expect text to be utf-8 encoded and do proper decoding.
- Wehn writing to stdout file, write the raw bytes without translation.

Note Python's `sys.stdout.buffer` does not do translation when writing to stdout console
like Rust's stdout.

For now, my main motivation of this change is to fix chg on Python 3.
