Currently port usage is hard-coded to the default port layout, cli commands are coming in a future commit. This decouples all code from the global 'serialPorts' structure which has been removed. Any code that needs to use a serial port can use findOpenSerialPort() and openSerialPort() and maintain it's own reference to the port. Ports can switch between functions. e.g. by default cli/msp/telemetry/gps passthrough all use USART1. Each port maintains it's current function. see begin/endSerialPortFunction. There are only certain combinations of serial port functions that are supported, these are listed in serialPortFunctionScenario_e. This commit also adds a few 'static' keywords to variables that should have been. There a a few other minor fixes and tweaks to various bits of code that this uncovered too.
