* Make `decl_error!` errors usable

This pr implements support for returning errors of different pallets in
a pallet. These errors need to be declared with `decl_error!`.

The pr changes the following:

- Each dispatchable function now returns a `DispatchResult` which is an
alias for `Result<(), DispatchError>`.
- `DispatchError` is an enum that has 4 variants:
  - `Other`: For storing string error messages
  - `CannotLookup`: Variant that is returned when something returns a
  `sp_runtime::LookupError`
  - `BadOrigin`: Variant that is returned for any kind of bad origin
  - `Module`: The error of a specific module. Contains the `index`,
  `error` and the `message`. The index is the index of the module in
  `construct_runtime!`. `error` is the index of the error in the error
  enum declared by `decl_error!`. `message` is the message to the error
  variant (this will not be encoded).
- `construct_runtime!` now creates a new struct `ModuleToIndex`. This
struct implements the trait `ModuleToIndex`.
- `frame_system::Trait` has a new associated type: `ModuleToIndex` that
expects the `ModuleToIndex` generated by `construct_runtime!`.
- All error strings returned in any module are being converted now to `DispatchError`.
- `BadOrigin` is the default error returned by any type that implements `EnsureOrigin`.

The finality-grandpa module needs two sets of functionalities from the
network:

1. Everything gossip related, e.g. event_stream, write_notification, ...

2. The ability to set a fork sync request for a specific block hash.

Instead of embedding (2) inside of (1) this patch extracts (2) from (1)
having finality-grandpa depend on a `Network` that fulfills the
`network_gossip::Network` trait and that can set block sync requests.

On the one hand this improves the overall structure splitting things
that don't logically belong together. On the other hand it does
reintroduce a lot of trait bounds within finality-grandpa.
