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

Fixed used index and available index. These are modded by the queue size in the ring only. The index continues to increase until it naturally wraps at the data size

Right now, we return a pointer by usize. This is not good programming in
...
Rust. Instead, the scheduler needs to be modified to return a process
structure's reference. Then, we can extract the fields and then switch.
However, this will require us to have to change how the PROCESS_LIST
works. Since it uses move constructs, we cannot move a process out of it
when we replace the process list.
