Implement userdata export.
...
A very simple implementation, as we are very short on remaining
block RAM. Simply blindly copies the entire userdata area to the
SD card. This may subject the SD card to some extra wear, as well
as potentially read-disturb some Flash memory pages, but this would
require more code.
