bmap_file_checksum is going to be used to check the integrity of the file. It is now included in the Bmap struct type and the builder. Signed-off-by: Rafael Garcia Ruiz <rafael.garcia@collabora.com>
Before using a Bmap file checks if its checksum is correct for the current bmap file. Bmap checksum is the application of Sha256 to the file data. When the bmap file is created, the value of the checksum has to be zero (all ASCII "0" symbols). Once calculated, zeros are replaced by the checksum, notice this modifies the file itself. In order to calculate the checksum before using it and compare it with the original, we need to set the field as all "0" before applying Sha256.
