Byte-precise size estimate for fees
...
Fixes issue #232 .
It assumes largest possible signature size for all inputs. For segwit
multisig it can be .25 bytes off due to difference between segwit
encoding (varint) vs. non-segwit encoding (op_push) of the multisig script.

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.
