Closes https://github.com/paritytech/polkadot-sdk/issues/2319 Changes: - Ensure that only `enqueue_message(s)` is callable from within the message processor. This prevents messed up storage that can currently happen when the pallet is called into recursively. - Use `H256` instead of `[u8; 32]` for clearer API. ## Details The re-entracy check is done with the `environmental` crate by adding a `with_service_mutex(f)` function that runs the closure exclusively. This works since the MQ pallet is not instantiable. --------- Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com>

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
