  Issue 5379 - applies patch supplied by philipp hagemeister to fix
  many problems with the ancient mcast.py demo code.
........

Run 2to3 over the Demo/ directory to shut up parse errors from 2to3 about lingering print statements.

number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

From SF patch #852334.

Also got rid of unnecessary use of eval() and regsub.gsub().

I found this in a mail of two and a half years ago from Yusuf Goolamabbas.
