// Version and Crypto tags are written to the wire with a big-endian
// 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_t, 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.
