94bcff28b1 p2p: Add wrappers for messages that use `Vec` (rustaceanrob)
Pull request description:
To move `p2p` into a crate:
1. All `Encodable` implementations for `p2p` must be defined in `p2p`. To accomplish this, and anything else in the future related to encoding, I added a `deser` module with the necessary macro to implement `Encodable` for `Vec<T> where T: Encodable`.
2. Because the orphan rule would apply for implementing `Encodable`for `Vec` within `p2p`, three types defined within `p2p` are used to wrap the `Vec` and snake around the orphan rule.
