fs: Break fs package to top-level and introduce ObjectAPI interface. ObjectAPI interface brings in changes needed for XL ObjectAPI layer. The new interface for any ObjectAPI layer is as below ``` // ObjectAPI interface. type ObjectAPI interface { // Bucket resource API. DeleteBucket(bucket string) *probe.Error ListBuckets() ([]BucketInfo, *probe.Error) MakeBucket(bucket string) *probe.Error GetBucketInfo(bucket string) (BucketInfo, *probe.Error) // Bucket query API. ListObjects(bucket, prefix, marker, delimiter string, maxKeys int) (ListObjectsResult, *probe.Error) ListMultipartUploads(bucket string, resources BucketMultipartResourcesMetadata) (BucketMultipartResourcesMetadata, *probe.Error) // Object resource API. GetObject(bucket, object string, startOffset int64) (io.ReadCloser, *probe.Error) GetObjectInfo(bucket, object string) (ObjectInfo, *probe.Error) PutObject(bucket string, object string, size int64, data io.Reader, metadata map[string]string) (ObjectInfo, *probe.Error) DeleteObject(bucket, object string) *probe.Error // Object query API.
