When --test-enable is used, it is expected that test output is visible,
thus using log-level INFO is natural.
On the down side you lose the nice blue hint that tests did actually
run when --log-level test was given.

By giving control on the error handling in
tool.ustr(), we let the caller decide what
should happen with invalid characters.
e.g. with errors="replace", all invalid
characters will be replaced by the UTF-8
question-mark character U+FFFD.

Warnings are handled with the other logs (and not always sent to stderr),
they also appear under a module __name__ channel instead of py.warn.
The disadvantage is that there is no longer specific warnings,
such as pending deprecation warning or deprecation warning.
