When a new journal file is created we write the header first, then sync and only then create the data and field hash tables in them. That means to other processes it might appear that the files have a valid header but not data and field hash tables. Our reader code should be able to deal with this. With this change we'll not map the two hash tables right-away after opening a file for reading anymore (because that will of course fail if the objects are missing), but delay this until the first time we access them. On top of that, when we want to look something up in the hash tables and we notice they aren't initialized yet, we consider them empty. This improves handling of some journal files reported in #487.
