* For sr-io, "std" should imply "no_oom" and "no_panic_handler".
Otherwise, rustc complains (correctly) about duplicate lang items.
* Add missing "runtime-io/std" features
* Fix compilation errors
* Prevent duplicate lang items
Rust does not allow duplicate lang items. When compiled without the
`std` feature, `sr-io` defines two lang items. Therefore, `sr-io`
compiled without `feature = "std"` must not be linked with `std`.
However, `pwasm-utils` and `wasmi-validation` both bring in `std` unless
compiled with `default-features = "false"`. This caused a duplicate
lang item error. Building both with `default-features = "false"`
prevents this error. When building with `feature = "std"`, they should
both be built with the `std` feature, so this feature needs to be
explicitly depended on.

* address grumbles
* Move Service::new to a macro
* Move function calls to macros
* Extract offchain_workers and start_rpc in separate function
In follow-up commits, we want to be able to directly call maintain_transaction_pool, offchain_workers, and start_rpc, without having to implement the Components trait.
This commit is a preliminary step: we extract the code to freestanding functions.
* Introduce an AbstractService trait
* Introduce NewService as an implementation detail of Service
* Implement traits on NewService instead
Instead of implementing AbstractService, Future, and Executor on Service, we implement them on NewService instead.
The implementations of AbstractService, Future, and Executor on Service still exist, but they just wrap to the respective implementations for NewService.
* Move components creation back to macro invocation
Instead of having multiple $build_ parameters passed to the macro, let's group them all into one.
This change is necessary for the follow-up commits, because we are going to call new_impl! only after all the components have already been built.
* Add a $block parameter to new_impl
This makes it possible to be explicit as what the generic parameter of the NewServiceis, without relying on type inference.
* Introduce the ServiceBuilder struct
Introduces a new builder-like ServiceBuilder struct that creates a NewService.
* Macro-ify import_blocks, export_blocks and revert_chain
Similar to the introduction of new_impl!, we extract the actual code into a macro, letting us get rid of the Components and Factory traits
* Add export_blocks, import_blocks and revert_chain methods on ServiceBuilder
Can be used as a replacement for the chain_ops::* methods
* Add run_with_builder
Instead of just run, adds run_with_builder to ParseAndPrepareExport/Import/Revert. This lets you run these operations with a ServiceBuilder instead of a ServiceFactory.
* Transition node and node-template to ServiceBuilder
* Transition transaction-factory to the new service factory
This is technically a breaking change, but the transaction-factory crate is only ever used from within substrate-node, which this commit updates as well.
* Remove old service factory
* Adjust the AbstractService trait to be more usable
We slightly change the trait bounds in order to make all the methods usable.

Given the following situation: A validator 'A' is not supposed to be
connected to the public internet to protect it from e.g. a DoS attack.
Instead it connects to a sentry node 'sentry-A' which connects to the
public internet. Validator 'B' can reach validator 'A' via sentry node
'sentry-A' and vice versa.
A sentry node needs to participate in the grandpa gossip without
becoming a validator itself in order to forward these message to its
validator. This commit adds a new command line flag (`--grandpa-voter`)
forcing a node to participate in the grandpa voting process even though
no `--key` was specified. Due to the fact that it does not have a key,
it does not become a validator in the network.
In order to simulate the above situation this commit also adds a Docker
Compose file (`scripts/sentry-node/docker-compose.yml`) with further
documentation.
