Commit message

Increase MAXSEQNO to avoid "MySQL protocol limit reached, you cannot send more than 4GB of data"

Description of the change

By Polystar:

Increasing MAX_SEQNO to avoid "MySQL protocol limit reached, you cannot send more than 4GB of data" when using LOAD DATA INFILE with big sizes. The MAX_SEQNO was wrong, causing it to be impossible to send queries of larger since than about 2MB (each packet is 8192 bytes multiplied with 255 is 2088960 bytes). I just increased the MAX_SEQNO to a very high value, not sure if the Mysql/MariaDB server actually can handle it.
