Because fscking a blob has always been a noop, we didn't bother passing around the blob data. In preparation for content-level checks, let's fix up a few things: 1. The fsck_object() function just returns success for any blob. Let's a noop fsck_blob(), which we can fill in with actual logic later. 2. The fsck_loose() function in builtin/fsck.c just threw away blob content after loading it. Let's hold onto it until after we've called fsck_object(). The easiest way to do this is to just drop the parse_loose_object() helper entirely. Incidentally, this also fixes a memory leak: if we successfully loaded the object data but did not parse it, we would have left the function without freeing it. 3. When fsck_loose() loads the object data, it does so with a custom read_loose_object() helper. This function streams any blobs, regardless of size, under the assumption that we're only checking the sha1. Instead, let's actually load blobs smaller than big_file_threshold, as the normal object-reading code-paths would do. This lets us fsck small files, and a NULL return is an indication that the blob was so big that it needed to be streamed, and we can pass that information along to fsck_blob().
