	The problem is that some DDL statements (ALTER TABLE, CREATE TRIGGER, FLUSH TABLES, ...) when under LOCK TABLES need to momentarily drop the lock, reopen the table and grab the write lock again (using reopen_tables). When grabbing the lock again, reopen_tables doesn't pass a flag to mysql_lock_tables in order to ignore the impending global read lock, which causes a assertion because LOCK_open is being hold. Also dropping the lock must not signal to any threads that the table has been relinquished (related to the locking/flushing protocol). The solution is to correct the way the table is reopenned and the locks grabbed. When reopening the table and under LOCK TABLES, the table version should be set to 0 so other threads have to wait for the table. When grabbing the lock, any other flush should be ignored because it's theoretically a atomic operation. The chosen solution also fixes a potential discrepancy between binlog and GRL (global read lock) because table placeholders were being ignored, now a FLUSH TABLES WITH READ LOCK will properly for table with open placeholders. It's also important to mention that this patch doesn't fix a potential deadlock if one uses two GRLs under LOCK TABLES concurrently. mysql-test/r/lock_multi.result: Add test case result for Bug#32395 mysql-test/r/trigger_notembedded.result: Add test case result for Bug#32395 mysql-test/t/lock_multi.test: Add test case for Bug#32395 mysql-test/t/trigger_notembedded.test: Enable test case for Bug#32395 sql/ha_ndbcluster.cc: Update close_cached_tables usage. sql/ha_ndbcluster_binlog.cc: Update close_cached_tables usage. sql/mysql_priv.h: Update close_cache_tables prototype. sql/set_var.cc: Update close_cached_tables usage and set flag to wait for tables with placeholders. This is one of the places where a GRL can be obtained. sql/sql_base.cc: Preserve old version for write locked tables and ignore pending flushes and update close_cache_tables to take into account name locked tables. sql/sql_parse.cc: Update close_cached_tables usage and pass flag so that name locked tables are waited for. sql/sql_table.cc: Protect the table against a impending GRL if under LOCK TABLES.
