This PR extends the Host serial port emulation to include local physical devices using the `--device` command-line option. For example: ``` make run HOST_UART_OPTIONS="--uart=0 --device=/dev/ttyUSB0" ``` The `--device` option must follow the `--uart` option. Another example: ``` make run HOST_UART_OPTIONS="--uart=0 --device=/dev/ttyUSB0 --uart=1 --device=/dev/ttyUSB1" ``` The port is opened when `uart_init` gets called. The default baud rate is whatever the application has requested. This can be overridden as follows: ``` make run HOST_UART_OPTIONS="--uart=0 --device=/dev/ttyUSB0 --baud=921600" ```
