No description provided.

It only happens when things go badly, which is why it doesn't cause
problems, but when moving things around, triggering the error, we
currently get a formatting error rather than the actual error.

Because most calling places in python configure don't actually want to
deal with encodings, although in practical terms they should, make
get_cmd_output handle it itself.

Places that explicitly do want bytes can keep using subprocess directly.

As a consequence, we can replace the encoded_open function that did the
same in an opt-in manner.

Make it a hard error when the sandbox returns non-unicode strings.
This should help quickly catch any remaining non-unicode string that
are not caught by automation.

The configure sandbox has wrapped subprocess methods to do it since
bug 1520394.
