py3: ditch email.parser.BytesParser which appears to be plain crap
As I said before, BytesParser is a thin wrapper over the unicode Parser,
and it's too thin to return bytes back. Today, I found it does normalize
newline characters to '\n's thanks to the careless use of TextIOWrapper.
So, this patch replaces BytesParser with Parser + TextIOWrapper, and fix
newline handling. Since I don't know what's the least bad encoding strategy
here, I just copied it from BytesParser.
I've moved new parse() function from pycompat, as it is no longer a trivial
wrapper.
