Added Registers to CPU so we don't have to hardcode the register number. This makes it easier to read and figure out what's happening

Reworked file system, still much to do, however, now we can get a file by its name instead of inode number.

Added locking to the scheduler. Since this is invoked so often, it causes a race with the test_elf process.

Don't let init sleep. This will cause us to hang in the scheduler.

Use Rust out-of-the-box now that it has full support for RISC-V. We need
cargo-binutils and so forth to run these. But, for now all we need is to
run cargo run and it should invoke qemu for us based on .cargo/config
