  message:
    Fix Bug#47991 InnoDB Dictionary Cache memory usage increases indefinitely
    when renaming tables
    
    Allocate the table name using ut_malloc() instead of table->heap because
    the latter cannot be freed.
    
    Adjust dict_sys->size calculations all over the code.
    
    Change dict_table_t::name from const char* to char* because we need to
    ut_malloc()/ut_free() it.
