[New-bugs-announce] [issue27940] xml.etree: Avoid XML declaration for the "ascii" encoding

New submission from STINNER Victor:
The ElementTree module (xml.etree) avoids the XML declaration for "utf-8" and "us-ascii" codecs, but not for the "ascii" encoding.
Attached patch avoids the XML declaration for the "ascii" codec since it's a subset of UTF-8 and UTF-8 is the default encoding of XML.
The patch also normalizes the encoding name to handle aliases like "utf8" (UTF-8) or "us_ascii" (ASCII).
The patch adds unit tests.
By the way, I'm surprised that the special encoding "unicode" relies on the *current* locale encoding when the XML declaration is requested. Why not alway susing UTF-8 for *unicode* instead of the locale encoding?
My unit test tests different locale encodings.
