Mostly mechanical. Creating a `CommonTransport` yields an
`io::Result<_>` now since creating the `DnsConfig` may fail with an
`io::Error` when creating the `ThreadPool`.
The `DnsConfig` `Transport` impl had to be changed slightly:
(a) PR [[1311]] requires some `Send` bounds.
(b) The async block had to be changed to work around lifetime inference
issues which resulted in an "one type is more general than the other"
error.

The functionality is available through `Multiaddr::replace`.
What we currently call "nat_traversal" is merley a replacement of an IP
address prefix in a `Multiaddr`, hence it can be done directly on
`Multiaddr` values instead of having to go through a `Transport`.
In addition this PR consolidates changes made to `Multiaddr` in
previous commits which resulted in lots of deprecations. It adds some
more (see below for the complete list of API changes) and removes all
deprecated functionality, requiring a minor version bump.
Here are the changes to `multiaddr` compared to the currently published
version:
1. Removed `into_bytes` (use `to_vec` instead).
2. Renamed `to_bytes` to `to_vec`.
3. Removed `from_bytes` (use the `TryFrom` impl instead).
4. Added `with_capacity`.
5. Added `len`.
6. Removed `as_slice` (use `AsRef` impl instead).
7. Removed `encapsulate` (use `push` or `with` instead).
8. Removed `decapsulate` (use `pop` instead).
9. Renamed `append` to `push`.
10. Added `with`.
11. Added `replace`.
12. Removed `ToMultiaddr` trait (use `TryFrom` instead).
Replace the listener and address pair returned from `Transport::listen_on` with just a listener that produces `ListenerEvent` values which include upgrades as well as address changes.
