The on-disk consistency checks in git-fsck(1) are conceptually
backend-specific: while connectivity checks and object-level parsing
checks are generic, verifying the physical integrity of packfiles and
loose objects is meaningful only to backends that use these formats:
Having these checks live in "builtin/fsck.c" violates that layering,
because it forces the command to reach directly into format-specific
internals.
Provide new infrastructure to make these format-specific checks
pluggable and implement stubs for the different source types we already
have. In subsequent commits we'll move functionality over piece by
piece.
