fsck_object(): allow passing object data separately from the object itself
When fsck'ing an incoming pack, we need to fsck objects that cannot be read via read_sha1_file() because they are not local yet (and might even be rejected if transfer.fsckobjects is set to 'true'). For commits, there is a hack in place: we basically cache commit objects' buffers anyway, but the same is not true, say, for tag objects. By refactoring fsck_object() to take the object buffer and size as optional arguments -- optional, because we still fall back to the previous method to look at the cached commit objects if the caller passes NULL -- we prepare the machinery for the upcoming handling of tag objects. The assumption that such buffers are inherently NUL terminated is now wrong, of course, hence we pass the size of the buffer so that we can add a sanity check later, to prevent running past the end of the buffer.
