 // representation of the name of the tag.  For example
 // the client hello tag (CHLO) will be written as the
 // following 4 bytes: 'C' 'H' 'L' 'O'.  Since it is
 // stored in memory as a little endian uint32, we need
 // to reverse the order of the bytes.

 // We use a macro to ensure that no static initialisers are created. Use the
 // MakeQuicTag function in normal code.
