WL#3726 "DDL locking for all metadata objects".
After review fixes in progress. Adjusted test case
according to review.
mysql-test/suite/rpl/r/rpl_view_multi.result:
Changed test case to check that statements are replicated
properly instead of directly inspecting binary log. Also
made result file more readable by adding echo there it
was appropriate. Moved test case to "rpl" suite.
mysql-test/suite/rpl/t/rpl_view_multi.test:
Changed test case to check that statements are replicated
properly instead of directly inspecting binary log. Also
made result file more readable by adding echo there it
was appropriate. Moved test case to "rpl" suite.

# concurren connections and manifest themselves as wrong binary log

# sequence which results in broken replication. In principle we are
