> We have some old-style try/finally to close files in DataStorage and Storage, let's update
them.
> Also a few small cleanups:
> * Actually check that tryLock returns a FileLock in isPreUpgradableLayout
> * Remove unused parameter from writeProperties
> * Add braces for one-line if statements per coding style
