Instead of relying on the name of the chain spec file, we now use the
`is_*` methods for this.

this will account for 'dummy' cores due to maxValidatorsPerCore

* ProxyType MaxEncodedLen

* import

* import

* fix dep and bump substrate

* Update Cargo.lock

* Use proper host configuration everywhere

* Fix dumb errors

* enable Config for Paras

* fix

* Bump Rococo/Wococo `spec_version` used by the bridge relayer

* Prevent bridge relayer from being part of workspace

This allows us to build the relayer without pulling in all its
dependencies into the Polkadot repo by indicating its manifest path when
building.

* Revert "Bump Rococo/Wococo `spec_version` used by the bridge relayer"

This reverts commit 90fdeecb.

* Replace NetworkStatusSinks with Arc<NetworkService>

* update Substrate

It should rather be updated manually with proper `Cargo.lock` updates at least until we switch to crates.io versions. See #3109 as an example of that (bad) update.

* validator_discovery: small tweak in retrying logic

* validator_discovery: use timeouts instead

* Introduce polkadot code substitute

This introduces a code substitute for the on-chain wasm of Polkadot from
block
`0x86aa36a140dfc449c30dbce16ce0fea33d5c3786766baa764e33f336841b9e29`
on wards. The underlying problem was that there exists some
miscompilation by the rust compiler in the wasm runtime that results in
state mismatches between the native/wasm runtime of the
the 0.8.30 release. This resulted in blocks being authored by the native
runtime not being importable by nodes using the wasm runtime. The
on-chain wasm is replaced by a wasm build from the 0.8.30 using the
rustc nightly from 1.03.2021.

* update the wasm substitute blob

* update Substrate
