8520dd8df2 Update the names of some member variables in comments to refect reality.
Apparently this was forgotten when this code was derived from the BSD
openprom(4).

630c60c775 - Move OFW_NAME_MAX, used as a limit for OFW property names and device
identifiers, to openfirmio.h as OFIOCMAXNAME, so programs can use it
  for buffer sizes etc.
  Note: Although this is only a rough upper limit to make the code more
  robust and to prevent the allocation of ridiculous amounts of memory,
  the current limit of one page (8191 + '\0' in openfirm_getstr()) still
  appears a bit high. The maximum length of OFW property names is 31.
  I didn't find a maximum length for the device identifiers in the OFW
  documentation but it certainly is much smaller than 8191, too.
- Enable the OFIOCSET ioctl, i.e. move it out from under #if 0.
- Don't use openfirm_getstr() for the property value in OFIOCSET, there
  are also properties whose values aren't strings and it makes sense to
  use a different maximum length for property values than OFW_NAME_MAX/
  OFIOCMAXNAME. The maximum accepted property value is defined in
  openfirmio.h as OFIOCMAXVALUE (currently the maximum size of the value
  of the nvramrc property).
- Make OFIOCSET not return EINVAL when OF_setprop() returns a different
  length for the written value than it was told to write, this is normal
  for the text string values of the properties in the OFW /options node.
  Instead, only return EINVAL if OF_setprop() returned -1 (value could
  not be written or property could not be created). Add a comment about
  the specialty of the OFW /options node.
- Make OFIOCSET return the length of the written value returned by
  OF_setprop(), just like OF_getprop() does. Quite useful, at least for
  debugging.

930f46e30b Add a pseudo device which allows to access the OpenFirmware device tree
via ioctl()s. This was ported from NetBSD and adapted a bit to better
match our OpenFirmware support code.
