Parachain execution yields messages to send (#96)

Browse Source 
* read head-data directly out of WASM memory

* implement ext_post_message for parachain WASM

* further refactoring of the parachain module

* add externalities error type

* accumulate posted messages when validating parachain candidate

* define Extrinsic type in primitives

* availability-store: store extrinsic data

* compute extrinsic and check against candidate

* add some egress queue tests

* grumbles & substrate update

* ensure everything builds
