Subject changed from rbd_metadata_list API function does not work properly to Issues with C API image metadata retrieval functions

Also, there is an issue with rbd_metadata_get function: on success it does not set update val_len param (which might be ok), but it also does not copy the final '\0' character to the value buffer. As a result the caller can't tell the value length until it pre-fills the buffer with zeros.
