/**
Print "SET skip_replication=..." statement when needed.
Not all servers support this (only MariaDB from some version on). So we
mark the SET to only execute from the version of MariaDB that supports it,
and also only output it if we actually see events with the flag set, to not
get spurious errors on MySQL@Oracle servers of higher version that do not
support the flag.
So we start out assuming @@skip_replication is 0, and only output a SET
statement when it changes.
