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.
