EXA: Only record damage generated by rendering operations.

Browse source 
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.
