freemodbus: Fix bug with incorrect coils read mask Contains two different component folders per each implementation (serial_master and serial_slave) with concrete ports. Added common public api for master and slave and common interface for master and slave implementation. Add support of cmake system (added cmake files). Added sdkconfig.defaults files for slave and master modbus examples. Updated make file and KConfig for freemodbus component Update according to review and fix doxygen warnings Fix Doxyfile to pass documentation build Update headers and change interface file names as per review comments Merge branch feature/freemodbus_move_rs485_mode_control Update after review: The stack modbus folder updated to support master and slave ports together and moved into freemodbus/modbus Stack and port files updated to remove duplicated simbols Make file, KConfig and CMakeLists.txt updated to compile master and slave stacks, common interface and concrete implementations of ports Stack callback functions execute callbacks using interface pointer from concrete port implementation User can instantiate any of concrete port using common API (only one concrete port at a time) and it does not require to select port by KConfig Port pins and mode configuration moved into example files from port files to allow user select pins and port mode (customer request) Changes tested using pymodbus, ModbusPoll and communication between two boards Updated DoxyFile according to public include path Fix maximum instance size for slave (merge from master of customer issue) Fix critical section issue TW#28622 (change spin lock based critical section to semaphore) Move serial port files into component port folder for master and slave accordingly Fix example issue showed in the log when IO slave is not configured correctly Fix conflicts while merging from origin/master Fix errors handling in modbus controller interface + some final corrections according to review Update maximum allowed number of slaves in the network segment Fix bug with incorrect coils read mask Closes https://github.com/espressif/esp-idf/issues/858
