* Use the new protobuf messages that send accounts as strings (fixes#367)
* `stellar_signingAbort()` now takes an error message
* Operations now check if a transaction is being signed (fixes#368)
* Operations now return false on error or if the user cancels
* Stellar `fsm_*` methods now check operation result and return early if the operation fails
This PR also re-enables the stellar code in the firmware.
While technically part of the address, the coin prefix, e.g., bitcoincash:
is implicit and doesn't need to be checked by the user. We still
include it in the QR-code though.
Also set case-insensitive flag for QR-code.
Use `FLASH_PTR` macro to convert a flash address to a const pointer.
For real hardware it is just a cast, for emulator we subtract the
`FLASH_ORIGIN` and use it as index into the memory mapped flash file.
Make write access to flash with volatile pointers
Also use FLASH_PTR in DebugMemory* for now. This allows for reading and
writing the flash in the emulator or just crash it by reading outside
the flash...
Increase the size of the addresses in protobuf.
Fix layout2.c to handle longer addresses.
Add a field bech32_prefix to coins.h
Adapted the coins-gen script.
Added bech32 support in signing.c and transaction.c
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.
