Description: Improve the XLS parsing:
* Don't stop processing after an EOF which is not followed by a BOF, as there
are many records that can appear after it (like a graph).
* On unexpected BOF record, dump already extracted data before complaining and
freeing memory.
* Accept different versions of BOF and XF records.
* Add more #defines for record types.
