The next number (AUTO_INCREMENT) field of the table for write rows events are not initialized, and cause some engines (innodb) not correctly update the tables's auto_increment value. This patch fixed this problem by honor next number fields if present. mysql-test/extra/rpl_tests/rpl_auto_increment.test: Add test code for BUG#41986 mysql-test/suite/rpl/r/rpl_auto_increment.result: update test result file for BUG#41986 sql/log_event.cc: set next_number_field before writing rows, and reset next_number_field after finished writing rows
