Saleem Rashid 54b0869535 signing: Use Hasher instead of SHA256_CTX 2017-12-09 16:28:40 +01:00
Jochen Hoenicke e1fa7af1da 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.

Jochen Hoenicke b5fa8a266a 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.
