[Warner Losh]

Author: imp
Date: Sat Dec  2 00:07:19 2017
New Revision: 326445
URL: https://svnweb.freebsd.org/changeset/base/326445

Log:
  Fix random() and srandom() prototypes to match the standard.
  
  These prototypes were needlessly different from the standard. Fix them
  to be the same, and fix the surrounding code after the changes.
