[Dovecot] MASTER_AUTH_MAX_DATA_SIZE

[Mike Abbott]

In 2.0.17 you increased LOGIN_MAX_INBUF_SIZE from 1024 to 4096.
Should you also have increased MASTER_AUTH_MAX_DATA_SIZE from (1024*2) to 
(4096*2)?
/* This should be kept in sync with LOGIN_MAX_INBUF_SIZE. Multiply it by two
   to make sure there's space to transfer the command tag  */
