Previously, we defaulted to only printing dirty journal entries (which
means nothing would be printed after a clean shutdown) - this is usually
not what we want.

Now, we default to printing the biggest range that has no gaps or
missing entries.

-a, --all
  now means print all entries, not just contiguous entries

And we now have

-d, --dirty-only
  for the the previous default behaviour.

-D, --datetime
  Print out one line per journal entry, with datetime it was written

-L, --log-only
  Only print entries containing log messages

-F, --flush-only
  Only print flush commits

Additionally, we now print a line for missing journal entry ranges.

These make it easier to get an overall picture of what happened in the
journal - in particular, seeing how far back we can rewind before we
have gaps.

Add a tool for creating small image files.

Data is written out in a reproducible order, sequentially from the
start of the device.

Metadata is initially written to a temporary device, then after writing
out data, the metadata we want to keep (alloc info is left out by
default) is migrated to the real device.

Then, the image file is trimmed to minimum size and the temporary
metadata device dropped.
