Theodore Ts'o 46efd2d93c Rename warn() to warning() to fix symbol conflicts on BSD and Mac OS
This fixes a problem reported by Randal Schwartz:

>I finally tracked down all the (albeit inconsequential) errors I was getting

>warn(3) in BSD-style distros.  It'd take a "great rename" to change it, but if

It was annoying to me, too, when I was doing some mergetool testing on
Mac OS X, so here's a fix.
