  Log:
  Add security.jail.mount_allowed sysctl, which allows to mount and
  unmount jail-friendly file systems from within a jail.
  Precisely it grants PRIV_VFS_MOUNT, PRIV_VFS_UNMOUNT and
  PRIV_VFS_MOUNT_NONUSER privileges for a jailed super-user.
  It is turned off by default.
  
  A jail-friendly file system is a file system which driver registers
  itself with VFCF_JAIL flag via VFS_SET(9) API.
  The lsvfs(1) command can be used to see which file systems are
  jail-friendly ones.
  
  There currently no jail-friendly file systems, ZFS will be the first one.
  In the future we may consider marking file systems like nullfs as
  jail-friendly.
