SF patch# 1770008 by Christian Heimes (plus some extras).
Completely get rid of StringIO.py and cStringIO.c.
I had to fix a few tests and modules beyond what Christian did, and
invent a few conventions. E.g. in elementtree, I chose to
write/return Unicode strings whe no encoding is given, but bytes when
an explicit encoding is given. Also mimetools was made to always
assume binary files.

If the pickle has a tell() method, pos was the value of pickle.tell()
- before reading the current opcode. If the pickle is a string object,
- it's wrapped in a StringIO object, and the latter's tell() result is
+ before reading the current opcode. If the pickle is a bytes object,
+ it's wrapped in a BytesIO object, and the latter's tell() result is
used. Else (the pickle doesn't have a tell(), and it's not obvious how
to query its current position) pos is None.
