Subject: Bugfix 8079: fix require sys/ioctl.ph confilcts

  perl only allows a require to be done once. If it is done in two
  included modules the module or function in the module used second
  doesn't have the data in the required file in its scope. To prevent
  this I created a third module that contains the functions that require
  'sys/ioctl.ph' so that there is no longer a conflict.
