    xfs: remove the quotaoff log format from the quotaoff log item

    This one doesn't save a whole lot of memory, but still makes the
    code simpler.

    xfs: remove the dquot log format from the dquot log item

    No need to keep the dquot log format around all the time, we can
    easily generate it at iop_format time.

    xfs: format logged extents directly into the CIL

    With the new iop_format scheme there is no need to have a temporary buffer
    to format logged extents into, we can do so directly into the CIL.  This
    also allows to remove the shortcut for big endian systems that probably
    hasn't gotten a lot of test coverage for a long time.

    xfs: format log items write directly into the linear CIL buffer

    Instead of setting up pointers to memory locations in iop_format which then
    get copied into the CIL linear buffer after return move the copy into
    the individual inode items.  This avoids the need to always have a memory
    block in the exact same layout that gets written into the log around, and
    allow the log items to be much more flexible in their in-memory layouts.

    The only caveat is that we need to properly align the data for each
    iovec so that don't have structures misaligned in subsequent iovecs.

    Note that all log item format routines now need to be careful to modify
    the copy of the item that was placed into the CIL after calls to
    xlog_copy_iovec instead of the in-memory copy.

    xfs: introduce xlog_copy_iovec

    Add a helper to abstract out filling the log iovecs in the log item
    format handlers.  This will allow us to change the way we do the log
    item formatting more easily.

    The copy in the name is a bit confusing for now as it just assigns a
    pointer and lets the CIL code perform the copy, but that will change
    soon.
