[gopher] Gopher support in curl gone

[Brian Koontz <brian@pongonova.net>]

Despite having a version of curl on OS X (Panther) that supports
gopher, upon building the latest libcurl stuff on a Linux box, it
turns out that gopher hasn't been supported since at least 2006:

          David Shaw finally removed all traces of Gopher and we are now
          officially not supporting it. It hasn't been functioning for
          years anyway, so this is just finally stating what already was
          true. And a cleanup at the same time.

Guess we let this one slip by.  curl has always been the no-nonsense,
"go to" command line app for just about any protocol.  This might be a
worthy project for someone, to "unpatch" libcurl for gopher support.

Well, off to find gophfilt...
