* clinet/finality-grandpa: Make round_communication use bounded channel

`round_communication` returns a `Sink` and a `Stream` for outgoing and
incoming messages. The messages send into the `Sink` are forwarded down
to the network as well as send back into the `Stream` to ensure the node
processes its own messages.

So far, to send messages into the `Sink` back into the `Stream`, an
unbounded channel was used. This patch updates `round_communication` and
`OutgoingMessages` to use a bounded channel.

This is part of a greater effort to reduce the number of owners of
components within `finality-grandpa` and `network` as well as to reduce
the amount of unbounded channels. For details see d9837d7d and
5f80929d.

* client/finality-grandpa: Import futures03::future::ready at the top

* client/finality-grandpa: Do not import ready into scope

Instead of importing futures03::future::ready into the scope, only
import futures::future03 into scope and call ready as furure03::ready.

This moves the wasm-allocator (`FreeingBumpHeapAllocator`) into its own
crate `sp-allocator`. This new crate can theoretically provide multiple
different allocators. Besides moving the allocator, this pr also makes
`FreeingBumpHeapAllocator` compile on `no_std`.

See #4702 for details.

* fixes trigger-contracts-ci job to actually depend on build-linux-substrate

* client/authority-discovery/Cargo.toml: Update dependency

* client/authority-discovery: Pass packet payload and addresses as slice

Starting with Bytes 0.5 `Vec<T>` does not implement `Buf`, but `&[T]`
does.

* Support `u128`/`i128` in runtime interface

This implements support for `u128`/`i128` as parameters/return value in
runtime interfaces. As we can not pass them as identity, as for the
other primitives types, we pass them as an pointer to an `[u8; 16]` array.

* contracts: Add Evicted and Restored events

* fix doc comment

* emit Evicted event immediately and add tombstone flag bool

* Pass an executor through the Configuration

* Make tasks_executor mandatory

* Fix tests

* Make debug builds more usable

This pr makes debug builds more usable in terms of `cargo run -- --dev`.

1. `--dev` activates `--execution native`, iff `--execution` is not
given or no sub `--execution-*` is given.
2. It was probably a mistake to compile WASM in debug for a debug build.
So, we now build the WASM binary always as `release` (if not requested
differently by the user). So, we trade compilation time for a better
debug experience.

* Make sure we only overwrite default values

* Make it work

* Apply suggestion

Some fixes after: https://github.com/paritytech/substrate/pull/4502

This removes the unwanted `expect`s from `MultiSigner`. Instead we
convert from full to compressed in `TryFrom` and can return an error on
invalid input.

By using `cfg(doc)`, we can generate docs for modules which are only
available from `no_std`. This drastically improves the documentation for
the developers.

* Add rules and unfounding to society.

* Docs and event

* Extra bit of docs.

* Cunningly reduce complexity

* Remove candidates when unfounding.

* Remove suspended candidates when unfounding, too.

Adds a table to the rustdoc that shows how each individual type is
passed between the wasm and the host side.

* Ensure all votes are removed after tally

* Fix comment

* client/finality-grandpa: Reintegrate gossip validator report stream

The `finality-grandpa` `GossipValidator` is called by the `GossipEngine`
in a synchronous fashion on each gossip message. Its main task is to
decide whether to gossip the given message on, or whether to drop it.

In addition it also updates the reputation of a node's peers based on
the incoming gossip messages. To do so it needs to be able to report the
reputation change which it does through an unbounded channel (in order
to stay synchronous).

Previously the receiving side of this channel would be handled by a new
task, polling the channel and forwarding the changes to a clone of the
`GossipEngine` that it would own.

Instead the receiver of the above mentioned channel is now being polled
by the `NetworkBridge` within its `Future::poll` implementation.
Reputation changes are reported through the already existing
`GossipEngine` instance within `NetworkBridge`.

For details on the overall goal, see d9837d7d.
