ALTER TABLE IMPORT enhancement

Details

    Description

      The feature introduces simplified workflow:

      FLUSH TABLES t1 FOR EXPORT;
      		 
      --copy_file $MYSQLD_DATADIR/test/t1.cfg $MYSQLD_DATADIR/test/t2.cfg
      		 
      --copy_file $MYSQLD_DATADIR/test/t1.frm $MYSQLD_DATADIR/test/t2.frm
      		 
      --copy_file $MYSQLD_DATADIR/test/t1.ibd $MYSQLD_DATADIR/test/t2.ibd
      		 
      UNLOCK TABLES;
      		 
      ALTER TABLE t2 IMPORT TABLESPACE;

      Previously, CREATE TABLE and ALTER TABLE…DISCARD TABLESPACE had to be executed, and the exact table definition from an existing .frm file could not be reused. This simplification addresses MDEV-15225.

      ha_innodb::open() should check for .ibd and .cfg files before actually opening a table.
