New CoinInfo separated from protobuf structures
Having CoinType using the protobuf structures has several disadvantages. - We always need to change trezor-common if we need a new field (like bech32 prefix) - Every time Trezor initializes it sends all this information out and nobody cares. - The protobuf structures add storage overhead due to their fixed size. I also removed most of the `has_` fields except for forkid: - `has_segwit` was merged with segwit - `has_coin_shortcut` can be replaced by test for NULL if necessary. The fields were reordered for better padding.
