Given a list of <pack>.idx files, this command validates the index file and the corresponding .pack file for consistency. This patch also uses the same validation mechanism in fsck-cache when the --full flag is used. During normal operation, sha1_file.c verifies that a given .idx file matches the .pack file by comparing the SHA1 checksum stored in .idx file and .pack file as a minimum sanity check. We may further want to check the pack signature and version when we map the pack, but that would be a separate patch. Earlier, errors to map a pack file was not flagged fatal but led to a random fatal error later. This version explicitly die()s when such an error is detected.
