svn commit: r288163 - stable/10/usr.bin/systat

[Xin LI]

Author: delphij
Date: Thu Sep 24 00:50:17 2015
New Revision: 288163
URL: https://svnweb.freebsd.org/changeset/base/288163

Log:
  MFC r287633:
  
   - Avoid accessing window properties directly, instead, use accessors.
     This should be no-op for now, but allows the code to work if we
     move to NCURSES_OPAQUE.
   - Use calloc() instead of malloc+bzero.
