python: Disable universal newlines
We are testing the behaviour of a tool, for different input files, each one using a different newline sequence. ('\n' on UNIX, '\r\n' on Windows, …) Unfortunately, when opening a file in text mode, Python 3 will by default enable the "universal newlines" mode, which means it replaces all the known newline sequences by '\n'. This (usually useful) behaviour breaks the tests, which are specifically trying to handle files with newline sequences different from '\n'. Disabling the universal newlines mode fixes the tests. However, to keep the script compatible with both Python 2 and 3, we must use the io.open() function instead of the open() builtin, as the latter only knows about the `newline` argument on Python 3.
