up header guard. Clean up structure definition for at2_entry so it's correct rather than derived from at_entry- this is important for unswizzling purposes. Add a whole bunch of unswizzle macros- they're not quite right yet but at least they're a start. Note that we now have, for at_entry, a 16 bit firmware handle as part of what had been at_reserved- this is to correlate ATIOs with CTIOs- and this must be carried along as part of a tag value to use with all CTIOs we send in relation to this ATIO.
