Sami Tolvanen 0a7b47397d Error correction: Use libfec in blockimg.cpp for recovery
Add block_image_recover function to rewrite corrupted blocks on the
partition. This can be attempted if block_image_verify fails.

Note that we cannot use libfec during block_image_update as it may
overwrite blocks required for error correction. A separate recovery
pass in case the image is corrupted is the only viable option.
