This makes file versioning way easier, since every file will have the
same version. I'll still need to manage minimum-supported versions, but
that shouldn't be too difficult going forward.

I want to reuse as much file code as I can for cache files, but I need a
new struct since data and cache files track different properties.

I don't think it makes sense that callers of file_open() are expected to
check the file version after opening. This should be something handled
by the file code so we can print a consistent error message.

And then rename the temporary file when closed. This protects users
data in case Ocarina gets killed.

I'm only setting this to a static string, so it doesn't make sense to
store this as a char array. Let's use a string pointer instead.

I eventually intend to remove the file_init() function, once everything
has been converted to C.

I also introduced a file_readf() function to make it easier to read a
formatted string from the file.

I also introduced a file_writef() function to make it easier to write a

And replace it with the function file_init(). Let's take this chance to
rework parts of the unit test as well.

This change also lets me remove the destructor, since code is expected
to call file_close() when IO is complete.

I add more detailed documentation matching what was in my DESIGN file.
In addition, I also prefix private File members with an underscore like
I do in other Ocarina classes.

I plan to introduce a new lib/ that sits between the gui and the backend
files (similar to how glibc sits between the kernel and userspace).
This gets the rename out of the way before I change my mind again.
