* Remove usage of unneeded Rust feature core_intrinsics

* core::intrinsics::abort -> arch::wasm32::unreachable

* Don't publish `core::intrinsics`.

* Disable panic_handler and alloc_error_handler for no_std non wasm builds

* Print an error if listener is closed

* Oops, forgot to commit this

* pallet-evm: log created address

* Bump spec_version

* Only emit Created event when ExitReason is Succeed

Hopefully this can be merged if the tests pass.

When messing with the signature, we need to make sure that we acutally
mess-up the signature. As the generated private/public key is random,
the signature is random as well. It can happen that `bytes[0] ==
bytes[2]` which makes the test fail. We fix this problem by just
inverting the bytes at `0` and `2`.

* client/finality-grandpa: Add regression test observer polling network

Ensure `Future` implementation of `ObserverWork` is polling its
`NetworkBridge`. Regression test for bug introduced in d4fbb897 and
fixed in 7d58ceeb

.

When polled, `NetworkBridge` forwards reputation change requests from
the `GossipValidator` to the underlying `dyn Network`. This test
triggers a reputation change by calling `GossipValidator::validate` with
an invalid gossip message. After polling the `ObserverWork` which should
poll the `NetworkBridge`, the reputation change should be forwarded to
the test network.

* Expose information about the extrinsic in the metadata

This pr exposes some information about the extrinsic used in the runtime
via metadata. The following information are exposed:

- Version of the extrinsic
- List of all signed extensions used by the extrinsic.

* Increment `spec_version`

To my knowledge, we don't keep wasm blobs checked in anymore.

It changes the way we extended the CLI functionalities of substrate to allow more flexibility. (If this was not clear, here is another version: it changes the `sc_cli` API to allow more flexibility).

This touches a few important things:
 - the startup of the async task with tokei:
    This was in node and node-template and I moved it to substrate. The idea is to have 1 time the code that handles unix signals (SIGTERM and SIGINT) properly. It is however possible to make this more generic to wait for a future instead and provide only a helper for the basic handling of SIGTERM and SIGINT.
 - increased the version of structopt and tokei
 - no more use of structopt internal's API
 - less use of generics

Related to #4643 and https://github.com/paritytech/cumulus/pull/42: the implementation of "into_configuration" and "get_config" are similar but with better flexibility so it is now possible in cumulus to have the command-line arguments only of the run command for polkadot if we want

Related to https://github.com/paritytech/cumulus/issues/24 and https://github.com/paritytech/cumulus/issues/34 : it will now be possible to make a configuration struct for polkadot with some overrides of the default parameters much more easily.
