Runtime Syscalls

[austinabell]

Task summary

Syscalls for runtime to use in actors execution. Most are proof related.

Most likely will interface https://github.com/filecoin-project/rust-filecoin-proofs-api for proof related things, but can probably use our encoding crate for the blake hash and our crypto crate for the verify signature.

Can ignore the TODO on the Syscalls type, as even if/when that switches, it will be simple to migrate over.

currently resides in vm/runtime/src/lib.rs but this is not a final location

Specification reference

• Spec is out of date, needs to match the interface used in specs-actors (I tried to match the interface as close to the go version when stubbing, but some types are likely to have to change slightly to match the interface with the rust proofs)
