gnutls on by default

[Lars Magne Ingebrigtsen]

I think it's time to switch gnutls on by default in network-stream.el
(for Emacsen that has support compiled in, that is).  It seems to work
fine for people who are using it, but we won't get a thorough testing
until more people are exposed to it.

So unless anybody objects, I'm going to commit that tomorrow.
