This fixes the firmware update function with bootloader v8, allows to
recover from interrupted updates with v7/v8, and does some code cleanup.
I believe that the code that allows to recover from a broken partition
table is also necessary to make flashing a different partition table
work at all, but I wasn't able to verify that, as I don't have any firmware
images with different partition tables to test with. In any case, I'm
pretty sure that it is working correctly now, as recovery from a mostly
empty flash without partition table has been tested successfully.
I have only tested the new code with bootloader v8, and I don't have the
documentation / interfacing guide for v7, so it would be great if anyone
could check that I didn't break updates for v7.
