Peter Hutterer 82c60232c0 dix: add valuator_mask_fetch_double() ...

Using this call simplifies callers that don't know if the mask bit is set.

Before:
  if (valuator_mask_isset(mask, valnum))
    value = valuator_mask_get_double(mask, valnum));
  else
    value = someothervalue;

Now:
 if (!valuator_mask_fetch_double(mask, valnum, &value))
    value = someothervalue;
