[Twisted-Python] IDNA problem in twisted

We just added a patch to our twisted to prevent twisted from doing idna validation. _idnaBytes and _idnaText not convert from bytes to unicode based on the type of the provided arg. We had to do this because there are domain names that youtube.com uses that are not valid under IDNA-2008

[Twisted-Python] log.callWithLogger not used - slows down reactor?

I'm hunting down performance issue in our code and spotted this in passing. As far I can tell nothing seems to need callWithLogger. I ran our 6k+ tests with this patch applied and everything worked. Does anything in the twisted world need it? Barry diff --git
