storage/maria/ma_blockrec.c:
  Generalized the way update and redo extends the size of a directory record.
  This will (for now) ensure that data files are idenitical after normal run and after a apply-log run.
storage/maria/ma_open.c:
  Disabled reservation of transid on rows (for now) as these are not yet used.
  (I had to disable this as otherwise update thougth rows had grown in size when they hadn't and we had thus different row sizes on update and redo, which caused different block information)
storage/maria/ma_test1.c:
  Added comment
storage/maria/ma_test2.c:
  Do commit on error/abort
storage/maria/ma_test_all.sh:

storage/maria/ma_test_recovery:
  More tests
