status and system variables

libtool does not like it and fails the build.

- When reopening table during recovery, don't set file length from file sizes as file is not flushed.
New feature in Aria recovery:
- Create database directory if missing.



storage/maria/ma_recovery.c:
  Don't print Query: twice when running maria_read_log
  Create database directory if missing. (Needed when running maria_read_log on an empty database direcory during testing)
  More DBUG_print
  Fixed bug: When reopening table during recovery, don't set file length from file sizes as file is not flushed.

(otherwise it often times out)
