Simplify the logging of ALTER TABLE operations, by making use of the
TRX_UNDO_RENAME_TABLE undo log record that was introduced in
commit 0bc36758ba.
commit_try_rebuild(): Invoke row_rename_table_for_mysql() and
actually rename the files before committing the transaction.
fil_mtr_rename_log(), commit_cache_rebuild(),
log_append_on_checkpoint(), row_merge_rename_tables_dict(): Remove.
mtr_buf_copy_t, log_t::append_on_checkpoint: Remove.
row_rename_table_for_mysql(): If !use_fk, ignore missing foreign
keys. Remove a call to dict_table_rename_in_cache(), because
trx_rollback_to_savepoint() should invoke the function if needed.
