The Rust libp2p-kad implementation can require iterative queries to use
disjoint paths for increased resiliency in the presence of potentially
adversarial nodes.

Allow Substrate users to enable this feature via the
`--kademlia-disjoint-query-paths` flag.

* Fix logging from inside the WASM runtime

When using `RuntimeLogger` to log something from the runtime, we didn't
set any logging level. So, we actually did not log anything from the
runtime as logging is disabled by default. This pr fixes that by setting
the logging level to `TRACE`. It also adds a test to ensure this does
not break again ;)

* Update frame/support/src/debug.rs

* *: Bump async-std to v1.6.5

Prevent users from using v1.6.4 which faces issues receiving incoming
TCP connections. See https://github.com/async-rs/async-std/issues/888
for details.

* client/network/src/gossip: Use channel instead of condvar

`async_std::sync::Condvar::wait_timeout` uses
`gloo_timers::callback::Timeout` when compiled for
`wasm32-unknown-unknown`. This timeout implementation does not fulfill
the requirement of being `Send`.

Instead of using a `Condvar` use a `futures::channel::mpsc` to signal
progress from the `QueuedSender` to the background `Future`.

* client/network/Cargo.toml: Remove async-std unstable feature

* client/network/src/gossip: Forward all queued messages

* client/network/gossip: Have QueuedSender methods take &mut self

* client/network/gossip: Move queue_size_limit into QueuedSender

The `queue_size_limit` field is only accessed by `QueuedSender`, thus
there is no need to share it between the background future and the
`QueuedSender`.

* client/network/gossip: Rename background task to future

To be a bit picky the background task is not a task in the sense of an
asynchonous task, but rather a background future in the sense of
`futures::future::Future`.

With the `OnRead` flow control option yamux "send[s] window updates only
when data is read on the receiving end" and not as soon as "a Stream's
receive window drops to 0".

Yamux flow control has proven itself. This commit removes the feature
flag. Yamux flow control is now always enabled.

* grandpa: remove duplicate authority_id function

* grandpa: rename is_voter to local_authority_id

* grandpa: cleanup rebuild_voter telemetry event

* Make `wasm-builder` print the rustc version

This makes `wasm-builder` print the rustc version that is being used to
compile the project. This is rather useful, because people can check
faster if the used rustc version is maybe known for being broken with
Substrate.

* Fixes bug in wasm-builder with cargo publish

There was a bug in wasm-builder which resulted in generating a
`Cargo.lock` in the project directory because of running `cargo
metadata`. This resulted in commands like `cargo publish` to fail (if
there was no `Cargo.lock` before building), because it checks that the
project directory isn't modified.

the DHT event stream.

* client/finality-grandpa: Use `Arc<dyn CryptoStore>` instead of SyncXXX

Instead of using `SyncCryptoStorePtr` within `client/finality-grandpa`,
which is a type alias for `Arc<dyn SyncCryptoStore>`, use `Arc<dyn
CryptoStore>`. Benefits are:

1. No additional mental overhead of a `SyncCryptoStorePtr`.

2. Ability for new code to use the asynchronous methods of `CryptoStore`
instead of the synchronous `SyncCryptoStore` methods within
`client/finality-granpa` without the need for larger refactorings.

Note: This commit uses `Arc<dyn CryptoStore>` instead of
`CryptoStorePtr`, as I find the type signature more descriptive. This is
subjective and in no way required.
