cabana: socketcan support

[pd0wm]

Test on a virtual socketcan device using.

sudo modprobe vcan
sudo ip link add dev vcan0 type vcan
sudo ip link set up vcan0
cangen vcan0 -g 1 -L 8 # Generate some fake data

Start cabana using ./cabana --socketcan vcan0.

TODO:

• [ ] Test with an actual device? Might need to patch up the panda socketCAN driver.
• [ ] Fix MacOS build
• [ ] Support multiple devices simultaneously (socketCAN uses one device per bus)

what would be needed to add support for USB connected black/red pandas on macOS (that does not have socketcan) - I see that Qt supports some CAN adapters https://doc.qt.io/qt-5/qtcanbus-backends.html and there is https://www.mac-can.com that also has plugin interface

[martinl]

nvm, I already found that panda is supported via usb serial interface. I'll go test if it works with macOS

[pd0wm]

Those are already supported! Just plug it in and select from the startup dialog.

Tested build on Linux, MacOS and C3.

@adeebshihadeh This is ready for review. I assume the failing CI is due to the changes in install_ubuntu_dependencies.h and will be fixed after merging?

@deanlee Any thoughts?

lgtm!
