fixed breaking in libc ABI

On December 18th I made a commit that accidentally broke the libc ABI,
the commit below fixes it.  If you updated current in the interim and
rebuilt ports due to complaints about strunvis or strunvisx you will
need to do so again after your next update.  Sorry for the breakage.

Subject: svn commit: r245305 - head/lib/libc/gen

Author: brooks
Date: Fri Jan 11 15:50:01 2013
New Revision: 245305
URL: http://svnweb.freebsd.org/changeset/base/245305

Log:
  In r244401 I accidently moved strunvis and strunvisx from version 1.0 to
  1.3 breaking the libc ABI. Revert that change (breaking the ABI again
  for users who updated after December 18th).
