from server/columnstore_cache. Commit message: Fixed bug in free locks that caused rows in cache to not be properly flushed Fixed by doing adding external_lock(F_UNLCK) in free_locks. I also moved unlock of cache_handler to be after changing lock type of cached tables to ensure that no one can use cached table while this is happening (as cache table is locked with write lock). I also fixed a wrong mutex order bug in ha_cache::flush_insert_cache() Other things: - Addded share::cached_rows to track inserted rows. This is only used for asserts to check the number of rows in the cache. - Fixed wrong mysql_file_chsize() in case of repair
