Refactor PeerServer event loop to avoid select!

Add a timeout to the `PeerServer` event loop.
...
I think this code could be cleaned up significantly (e.g., removing the
other use of select!) but that's potentially a larger change than this
PR.

Handle error conversions properly. ( #56 )
...
This adds a type alias, BoxedStdError, for a boxed std::error::Error
trait object, and uses it in the where bounds for the generic service
code. In the future, we may want to standardize on using
std::error::Error exclusively, but we would then possibly lose out on
backtrace information.

Initial tower-based peer implementation. ( #17 )
...
Add a tower-based peer implementation.
Tower provides middleware for request-response oriented protocols, while Bitcoin/Zcash just send messages which could be interpreted either as requests or responses, depending on context. To bridge this mismatch we define our own internal request/response protocol, and implement a per-peer event loop that scans incoming messages and interprets them either as requests from the remote peer to our node, or as responses to requests we made previously. This is performed by the `PeerService` task, and a corresponding `PeerClient: tower::Service` can send it requests. These tasks are themselves created by a `PeerConnector: tower::Service` which dials a remote peer and performs a handshake.

Rename `Services` to `PeerServices`.
...
This field is called `services` in Bitcoin and Zcash, but because we use
that word internally for other purposes, calling it `PeerServices`
disambiguates the meaning to "the services advertised by the peer",
rather than, e.g., a `tower::Service`.

I don't feel super strongly about this change, so I'm happy to drop it,
but it makes the parsing match statements line up nicely and aligns
naming with the naming used in Bitcoin.

Parse inv messages, refactor inventory vectors.
...
This removes the inventory vector structs from `zebra-chain` (as they
are really part of the network protocol) and refactors them into a
single `InventoryHash` type. This corresponds to Bitcoin's "inventory
vector" but with a different, better name (it's not a vector, it's just
a typed hash of some other item).
