svn commit: r280005 - head/sys/sys

New Revision: 280005
URL: https://svnweb.freebsd.org/changeset/base/280005

Log:
  Define a convenience macro, SYSCTL_OUT_STR() for handling strings the
  standard way (including the nulterm byte in the data returned to userland).
  
  This augments the existing sysctl_handle_string() in that this can be used
  with const strings without ugly inappropriate casting.
