Michel Dänzer 29586101dc EXA: Only record damage generated by rendering operations.
Recording damage from other operations (e.g. creating a client damage record)
may confuse the migration code resulting in corruption.

Option "EXAOptimizeMigration" appears safe now, so enable it by default. Also
remove it from the manpage, as it should only be necessary on request in the
course of bug report diagnostics anymore.
