Part of MDEV-5336 Implement LOCK FOR BACKUP Originally both table metadata lock and global read lock protection were acquired before getting TABLE from table cache. This will be reordered in a future commit with MDL_BACKUP_XXX locks so that we first take table metadata lock, then get TABLE from table cache, then acquire analogue of global read lock. This patch both simplifies FLUSH TABLES code, makes FLUSH TABLES to lock less and also enables FLUSH TABLES code to be used with backup locks. The usage of FLUSH TABLES changes slightly: - FLUSH TABLES without any arguments will now only close not used tables and tables locked by the FLUSH TABLES connection. All not used table shares will be closed. Tables locked by the FLUSH TABLES connection will be reopened and re-locked after all others has stoped using the table (as before). If there was no locked tables, then FLUSH TABLES is instant and will not cause any waits. FLUSH TABLES will not wait for any in use table. - FLUSH TABLES with a table list, will ensure that the tables are closed before statement returns. The code is now only using MDL locks and not table share versions, which simplices the code greatly. One visible change is that the server will wait for the end of the transaction that are using the tables. Before FLUSH TABLES only waited for the statements to end.
