It occures, that major DDL/DML functions support a subset of UTF-8(according with this) for table/column identifiers and only 'ALTER TABLE RENAME' doesn't support it because the mariadb plugin function ha_calpont_impl_rename_table_() replaces the initial query. I changed this and also replace push_warning() arguments according with recomendations given in server_code/sql/sql_error.cc to avoid possible sigabort.

Kindly take a look at the tiny functional tests results.

For QA: Please see Roman's tests.
