When doing Ethereum signTypedData, and the primaryType="EIP712Domain",
we completely ignore the "message" part and only sign the domain.
According to the community, this is technically allowed by the spec,
and may be used by ETH smart contracts to save on gas.
Test case generated by @MetaMask/eth-sig-util's library.
See: https://ethereum-magicians.org/t/eip-712-standards-clarification-primarytype-as-domaintype/3286
This keeps information about vendors and USB IDs in one place, and
allows us to extend with model-specific information later.
By default, this should be backwards-compatible -- TrezorClient can
optionally accept model information, and if not, it will try to guess
based on Features.
It is possible to specify which models to look for in transport
enumeration. Bridge and UDP transports ignore the parameter, because
they can't know what model is on the other side.
supersedes #1448 and #1449
If the device asks for a tx_hash which is not present in prev_txes,
raise a ValueError with some more detailed messaging about the missing
hash rather than the default dictionary lookup failure of KeyError.

* Changes from original PR
* Now that we are rejecting chain_ids of 0, we need to have the tests set the chain_ids to at least 1.
* Ran 'make gen' and uploaded changed files.
* Ran make style_check and fixed reported errors
* Added changelog files
* Reverted changes concerning chain_id 0 being rejected.
* Adds tests for MAX_CHAIN_ID and MAX_CHAIN_ID+1. Also reverts MAX_CHAIN_ID to the previous value.
* Added missing whitespace around arithmetic operator.

There's two udp calls in `UdpTransport._ping()`:
- socket.sendall(b"PINGPING") -> this will be instanteous, AND it will
raise if the receiving side is not listening.
- socket.recv() -> this will wait for SOCKET_TIMEOUT seconds, but only
in case the sendall() succeeded. This means that receiving side exists
and we are now waiting until it's awake enough to respond.
In conclusion, we avoid hammering emulator with PINGPINGs with a timeout
so short we don't see an answer. This should avoid the problem
occasionally seen in CI and described in #1668
API-compatibility with the original one is retained.
Now that we don't need to keep code parity with core, we could do some
changes that make life easier.
All generated classes are now in one file. This makes github diffs more
readable, at the cost of somewhat complicating inspecting individual
classes; however, that is something we shouldn't be doing anyway.
Enums are now implemented as enum.IntEnum.
The original class-level FIELDS member was restored.
Each field is now defined via protobuf.Field, which is easier to work
with in the codec, AND we're not stuffing defaults and flags into the
same field.
