Cleanup after query.
SYNOPSIS
THD::cleanup_after_query()
DESCRIPTION
This function is used to reset thread data to it's default state.
NOTE
This function is not suitable for setting thread data to some
non-default values, as there is only one replication thread, so
different master threads may overwrite data of each other on
slave.
