These errors are gone and replaced (in parity-ethereum) by plain io::Error. PR

This option is also gone (always true now).

Also fix the weird file structure by making `wasm_executor.rs` -> `wasm_executor/mod.rs`.

Closes #371
Introduces an availability store. Validators who are meant to guarantee available data will not cast votes until the data has been written to disk. Currently it resides in a fixed subdirectory of the general data directory, but we will make it configurable in the future.
Block data network requests are now answered from the store if not kept in memory already.
There is no protocol for discovering peer IDs for validators who have historic data available (yet).
