Image 0 did not work. We now get rid of bootloader_backup_irq_table and do this manually: We may not write to address 0 while an image is running. So for image 0 we write the lower 8 pages to the backup address. For all other images (ony image 1 currently) we write to *both*, the original address *and* the backup address. This is done because some addresses in the lower 8 pages *are* used at the original address and the bootloader doesn't (want to) know which addresses are which. There are more safeguards now: We refuse to write to the active or boot_next image (if boot_next is not boot_default). We mark the uploaded partition as not ok. Needs latest bootloader with commit ID a5771ae033b57.
