The block device API is going back into the BIOS API, so we can work on filesystem support using the Linux BIOS.

We can do DIR now in #36. Next step is a LOAD command - and to change RUN to verify that the application loaded is actually valid before jumping to it so you can't jump to garbage.

We'll need an array of "open file" objects. The file handle you give to a user will be an index into this array. Each object will have a volume index and a file handle for that volume. If a card is ejected, all files on that volume will be marked as errored. All open files will need to be closed when a program exits.
