* Kademlia: Optimise iteration over closest entries.
The current implementation for finding the entries whose keys are closest
to some target key in the Kademlia routing table involves copying the
keys of all buckets into a new `Vec` which is then sorted based on the
distances to the target and turned into an iterator from which only a
small number of elements (by default 20) are drawn.
This commit introduces an iterator over buckets for finding the closest
keys to a target that visits the buckets in the optimal order, based on
the information contained in the distance bit-string representing the
distance between the local key and the target.
Correctness is tested against full-table scans.
Also included:
* Updated documentation.
* The `Entry` API was moved to the `kbucket::entry` sub-module for
ease of maintenance.
* The pending node handling has been slightly refactored in order to
bring code and documentation in agreement and clarify the semantics
a little.
* Rewrite pending node handling and add tests.
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).
Update the protocols and transport subdirectories to the 2018 edition.
NB: The websocket transport cannot be moved to 2018 edition due to
websocket-rs's use of the keyword async as the name of a module.
* Add an Error associated type to transports
