device/trezor: webusb transport added, cmake fixes
- webusb transport based on libusb added. Provides direct access to Trezor via USB, no need for Trezor bridge. - trezor protocol message handler improved, no recursion used. Ready for upcoming integration tests. - libusb (for docker) bumped from v1.0.9 to v1.0.22, newer version required for webusb transport, for device enumeration. - cmake improvements and fixes. Cmake Trezor checks are moved to a dedicated CheckTrezor.cmake file. In case of a problem Trezor is excluded from build. - ifdefs made consistent to Ledger. - UDP Transport enumeration disabled by default in release mode

## Messages rebuild
|

|

Install `protoc` for your distribution.
|
||||
Install `protoc` for your distribution. Requirements:
|
||||
|
||||
- `protobuf-compiler`
|
||||
- `libprotobuf-dev`
|
||||
- `libprotoc-dev`
|
||||
- `python-protobuf`
|
||||
- `python`
|
||||
|
||||
Python 3 is required. If you don't have python 3 quite an easy way is
|
||||
to use [pyenv].
|
||||
|
||||
It is also advised to create own python virtual environment so dependencies
|
||||
are installed in this project-related virtual environment.
|
||||
Soft requirement: Python 3, can be easily installed with [pyenv].
|
||||
|
||||
### Python 2
|
||||
|
||||
Workaround if there is no Python3 available:
|
||||
|
||||
```bash
|
||||
python -m venv /
|
||||
pip install backports.tempfile
|
||||
```
|
||||
|
||||
Make sure your python has `protobuf` package installed
|
||||
### Regenerate messages
|
||||
|
||||
```bash
|
||||
pip install protobuf
|
||||
```
|
||||
|
||||
Regenerate messages:
|
||||
|
||||
```
|
||||
./venv/bin/python3 src/device_trezor/trezor/tools/build_protob.py
|
||||
cd src/device_trezor/trezor
|
||||
python tools/build_protob.py
|
||||
```
|
||||
|
||||
The messages regeneration is done also automatically via cmake.
