object-file API: split up and simplify check_object_signature()
Split up the check_object_signature() function into that non-streaming version (it accepts an already filled "buf"), and a new stream_object_signature() which will retrieve the object from storage, and hash it on-the-fly. All of the callers of check_object_signature() were effectively calling two different functions, if we go by cyclomatic complexity. I.e. they'd either take the early "if (map)" branch and return early, or not. This has been the case since the "if (map)" condition was added in 090ea12671b (parse_object: avoid putting whole blob in core, 2012-03-07). We can then further simplify the resulting check_object_signature() function since only one caller wanted to pass a non-NULL "buf" and a non-NULL "real_oidp". That "read_loose_object()" codepath used by "git fsck" can instead use hash_object_file() followed by oideq().
