Merge #261

261: Begin overhauling libtock_platform's syscalls trait for Tock 2.0. r=hudson-ayers a=jrvanwhy

I made the following changes to the design of `Syscalls`:

1. The trait is now designed for the (work-in-progress) Tock 2.0 syscalls rather
   than the Tock 1.0 syscalls.
2. The higher-level API that I previously intended to implement in the Platform
   type is now expressed in the form of provided functions in Syscalls.

So far, I have only implemented `yield`. I'm sending this for review now because it is already getting large, and I'd prefer to split it up into several PRs rather than send a single huge PR.

There is still significant design work to be done in terms of error handling for `subscribe`, `command`, both `allow`s, and `memop`.

EDIT: To everyone reviewing this, here is a [direct link to syscalls.rs](https://github.com/jrvanwhy/libtock-rs/blob/syscalls-2.0/core/platform/src/syscalls.rs), in case you want to read it *without* seeing the diff from the previous version.
