// Equal reports whether two messages are equal,
// by recursively comparing the fields of the message.
//
//   - Bytes fields are equal if they contain identical bytes.
//     Empty bytes (regardless of nil-ness) are considered equal.
//
//   - Floating-point fields are equal if they contain the same value.
//     Unlike the == operator, a NaN is equal to another NaN.
//
//   - Other scalar fields are equal if they contain the same value.
//
//   - Message fields are equal if they have
//     the same set of populated known and extension field values, and
//     the same set of unknown fields values.
//
//   - Lists are equal if they are the same length and
//     each corresponding element is equal.
//
//   - Maps are equal if they have the same set of keys and
//     the corresponding value for each key is equal.
//
// An invalid message is not equal to a valid message.
// An invalid message is only equal to another invalid message of the
// same type. An invalid message often corresponds to a nil pointer
// of the concrete message type. For example, (*pb.M)(nil) is not equal
// to &pb.M{}.
// If two valid messages marshal to the same bytes under deterministic
// serialization, then Equal is guaranteed to report true.
