    mkfs.ocfs2: Add 64bit journal support.

    The [no]block32 and [no]block64 journal options are added to mkfs -J.
    noblock32 and block64 will create 64bit-capable journals.

    With block64 enabled journals, the filesystem can be created larger than
    2^32 blocks.

    libocfs2: Support 64bit journals.

    libocfs2 is ensured to check the journal feature bits before continuing
    via the COMPAT_JBD2_SB filesystem feature.  fsck.ocfs2 can replay and
    recover 64bit journals.  tunefs.ocfs2 copies journal feature bits when
    creating new slots.  We are now safe to mark the feature bit supported.

    fsck.ocfs2: Fix feature bits, handle bad first journal.

    fsck.ocfs2 needs to make the feature bits consistent across all
    journals.

    While we're there, we can fix the fact that fsck.ocfs2 implicitly trusts
    the first journal file.  If the first journal is corrupt, it exits and
    refuses to repair the filesystem.

    Instead, we create a two-pass journal check scheme.  In the first pass,
    all journals are checked.  If we can find a sane disposition from one of
    them, we can then go about fixing all of them.

    Included in this patch is fixing journal superblock feature bits.

    mkfs.ocfs2: Add FEATURE_COMPAT_JBD2_SB.

    All filesystems that support FEATURE_COMPAT_JBD2_SB can handle journal
    superblock features.  We use this feature to prevent older fsck/tunefs
    from loading journal features they don't understand (since they never
    checked).  The code at this point will check for unknown features, and
    it doesn't know any.  Thus it can safely fsck/tune JBD2_SB filesystems
    it creates.

    libocfs2: Add features to ocfs2_make_journal()

    When we create/modify journals, we basically rewrite them.  The
    ocfs2_make_journal() function now takes the set of features we want in
    the journal.

    mkfs.ocfs2 and fsck.ocfs2 are updated but only sets an empty feature
    set.

    tunefs.ocfs2 now checks the feature bits and is smart enough to copy the
    feature set from other journals.

    libocfs2: Set and clear journal features.

    This adds functions to set and clear feature bits in the journal
    superblock.  Features are checked against the known feature set.

    fsck.ocfs2: Replay 64bit journals.

    Properly handle the new 64bit journal_block_tag_t.  This includes
    fsck.ocfs2's replay and debugfs.ocfs2's display.

    libocfs2: Check for unsupported features in the journal superblock.

    ocfs2_read_journal_superblock() should fail if it finds unsupported

    fsck.ocfs2: Move to JBD2 header and structures.

    Change all defines and structures to JBD2 structures.  This is backwards
    compatible with the JBD journals, and is capable of handling even the
    oldest ocfs2 filesystems.

    The only major functional change is to use journal_tag_size() instead of
    sizeof(journal_block_tag_t) when walking the descriptor block.
    fsck.ocfs2 and debugfs.ocfs2 are updated.

    We deliberately put JBD2_FEATURE_INCOMPAT_REVOKE in the set of known
    features.  We've never checked the feature set (we're about to), but
    we've always supported revoke.
