[phobos] Removing std.stdio.File.popen()

[Steve Schveighoffer]

Well, like I said, I wrote code that compiled.  I haven't been able to test it 
because of the "circular dependency" problem artifically introduced by the 
workaround for 3979 :)

I think it's correct, Walter sent me enough snipits from DMC's runtime internals 
so I could do it.  Only testing will tell....

BTW, are you in a position to test Rainer's patch on bug 3979?  I don't have 
time right now to build/test a compiler patch (not to mention, I've never built 
dmd before).

-Steve
