This example adds functionality to support basic communication in RS485 networks using Modbus protocol. This example uses FreeModbus stack and regular UART driver API to communicate in RS485 half duplex mode. Added initial support of modbus controller pure C api to access device parameters over Modbus transport. Move freemodbus stack and port files into components folder Move the modbus_controller interface into components idf folder Source files updated after review. Add modbus interface documentation docs/en/api-reference/protocols/modbus.rst porttimer.c: fix bug with timer1 selected in the Kconfig Add support of cmake system (added cmake files) Closes https://github.com/espressif/esp-idf/issues/858
