From ffd0820ab317542f8780aac475da590a4bdbc7a8 Mon Sep 17 00:00:00 2001

Subject: Deprecate taint/trust and related methods, and make the methods
 no-ops

This removes the related tests, and puts the related specs behind
version guards.  This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
