  Log:
  SVN rev 216573 on 2010-12-19 21:33:28Z by joerg
  
  Fix __retval vs. retval confusion: retval is meant to store the (userland)
  pointer where data is to be returned by ibask() (currently unimplemented),
  while __retval holds the value returned by the libgpib ibfoo() functions.
  
  The confusion resulted in the ibfoo() functions returning an uninitialized
  value except in situations where the GPIB activity has been terminated
  abnormally.
  
  Implement more of __ibsta: END and SRQI status bits (taken out of the
  uPD7210 IRQ status).
