bug #34518: loading intel hex files > 64k using record-type 4 

(Extended Linear Address Record)

Replace the change from r928 (handling of 0x8000000 offset in AVR32
files) by a completely different logic that no longer breaks hex files
for other devices starting with an offset; also apply a similar change
to S-record files, as well as when writing files.
