Variable initialization ahead of LOAD DATA INFILE not possible by validateLocalFileName pattern

The pattern in org.mariadb.jdbc.message.ClientMessage.validateLocalFileName requires that the sql statement - apart from leading comments - starts with the "LOAD DATA" statement.

The combination with other statements within the same sql string is blocked.

A statement like the this is therefor currently not possible:
{{SET @row = 0; LOAD DATA ... SET file_line_no = @row:=@row+1;
}}

The validateLocalFileName need be adjusted to allow other statements prior to the "LOAD DATA" statement in the sql string.
