* The receive and reply callbacks are called on the receiving (replica)
* side.
*
* Data can be exchanged between the sending and receiving sides using
* these callbacks by using the data_guid and data parameters. The data
* guid is used as an identifier to confirm the data type. Your callbacks
* that receive data must consult the data_guid before attempting to read
* the data parameter. This allows you to confirm that the same replication
* session plug-in is being used on both sides before making assumptions
* about the format of the data. The callbacks use these parameters as
* follows:
*
* pre - send data to replica
* recv - receive data from master
* reply - send data to master
* post - receive data from replica
*
* The memory used by data_guid and data should be allocated in the pre
* and reply callbacks. The replication plug-in is responsible for
* freeing this memory, so they should not be free'd in the callbacks.
*
* The return value of the callbacks should be 0 to allow replication
* to continue. A non-0 return value will cause the replication session
* to be abandoned, causing the master to go into incremental backoff
* mode.
