* Replace `listen_addr` with `local_addr`.
In `ListenerUpgrade`, `ConnectedPoint` and other event types where we
were previously using the listen address we now report the local address
of an incoming connection. The reason being that it is difficult to get
the listen address right. In case clients want to know, which listener
produced an incoming connection upgrade they are advised to use the
`ListenerId` for such purposes.
* Update transports/tcp/src/lib.rs

* Add listener ID and error event.
Report listener errors to client code so they are aware that an error
occurred within a listener. By default we continue to poll listeners
which produced an error, but clients can remove listeners by ID.
* tcp: Report errors.
Instead of silently waiting after errors we return all errors, but pause
after each error, before continuing.
* Add a test.
To ease testing, `Listener` is made generic and we test that no values
and errors are lost. Elapsed time between item generation is not
measured.
* Support the new methods in core-derive.
* Address review concerns.
* Remove `Display` impl of `ListenerId`.
* Add 'static bound to `on_listener_error` error.
The transport should be able to continue processing other connections.
An error to determine a socket's address is not a fatal condition but
may happen when a connection is immediately reset after being
established. By the time the programme asks for the remote address, the
socket may already be gone.
Fixes#1182.
* Update soketto and enable deflate extension.
* libp2p-deflate and libp2p-websocket share flate2.
Due to the way feature resolution works in cargo today, the `deflate`
feature of `soketto` will include `flate2` with feature `zlib` which is
then also active for the `flate2` that `libp2p-deflate` depends on. This
leads to compilation failures for WASM targets. This PR therefore moves
libp2p-deflate to the crates which are not available on WASM.
* Begin reimplementing the websocket transport.
* Add TLS support.
* Add support for redirects during handshake.
* Cosmetics.
* Remove unused error cases in tls module.
Left-overs from a previous implementation.
* No libp2p-websocket for wasm targets.
* Change tls::Config to make the server optional.
* Update transports/websocket/src/lib.rs

* Duplicate config methods.
As per PR review feedback.
* Map all 127.0.0.0/8 addresses to 127.0.0.1.
Since every local socket address in the 127.0.0.0/8 space is looped back
to 127.0.0.1/32 we should only have to report the later as the listen
address. For other addresses we still attempt to discover host addresses
when we encounter an unknown local address. We now also check that after
the host addresses have been reset that the address is now found,
otherwise we produce an error.
* Change listen address lookup.
Perform multiple steps:
1. Check for exact address match.
2. Else consider netmask and check for containment.
3. Else re-check host addresses and try 1 & 2 again.
4. Else report an error.
* Small fixes.
* Test and improve prefix_len.
* Simplify and inline the prefix_len logic.
* Add wasm-ext-transport
* Fix paths
* Adjust listen_on to return an Iterator
* Adjust read() to produce Iterator
* Remove map_err when possible
* Cargo fmt
* Adjust errors as well
* Small comment fix
* Revert "Adjust errors as well"
This reverts commit 97eb5149dafeaca9910a2809ee47e6d332ce1cb1.
* More dev on Debug
* Differentiate based on error
* Bump to 0.7.0
* Update CHANGELOG.md

* Update for #1078
* New version of multihash and multiaddr as well
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).
Wildcard IP addresses (e.g. 0.0.0.0) are used to listen on all host
interfaces. To report those addresses such that clients know about them
and can actually make use of them we use the `get_if_addrs` crate and
maintain a collection of addresses. We report the whole expansion at the
very beginning of the listener stream with `ListenerEvent::NewAddress`
events and add new addresses should they come to our attention.
What remains to be done is to potentially allow users to filter IP
addresses, for example the local loopback one, and to detect expired
addresses not only if a new address is discovered.
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.
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
* Improve raw swarm a bit
* Rename map_other to map
* Use source() instead of cause()
* RawSwarmIncErr -> IncomingError
