tests: test writing and recovering 64bit csum_v3 journals

Simple tests for the 64bit journal transaction creation code when
journal and metadata_csum are enabled.   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.
