[PATCH 13/25] tests: test writing and recovering checksum-free 32/64bit journals

["Darrick J. Wong" <darrick.wong@oracle.com>]

Simple tests for the journal transaction creation code.   We test
writing (bad) block bitmaps out through the journal and replaying them
via fsck, with a few twists:

(a) All bitmaps are committed (fs errors reported)
(b) All the bitmap blocks are revoked (no errors)
(c) The transaction is never committed (no errors)
(d) Same as (a), but debugfs gets to do the replay.

We also test:

(a) writing and replaying transactions with multiple
    descriptor blocks
(b) same, but with multiple revoke blocks.
(c) adding the 64bit flag to a journal
