add multi register area descriptors into concrete port (initial)
add create/destroy of area descriptors into concrete port
add the list of descriptors in common slave interface structure and init/destroy in concrete slave port
move r/w callback functions into common slave
final update of common slave interface wrappers add override API option in concrete port
update slave examples to check new feature
Add TCP port files to provide Modbus TCP interface for communication
Add freemodbus add tcp support for common master/slave iface and tcp example based on socket API
The communication between master and slave checked for each example serial_master, serial_slave (use ModbusPoll TCP)
update tcp example according netif changes, fix ci issues
update TCP slave implementation
update example_test.py to to set IP through stdin
update API documentation
event bit instead of semahore to lock communication resource
update default options and master/slave port files

Closes IDF-452
check master read write functions with array of registers)
fix master serial processing code and modbus controller to work with register array
modbus_master: add reading and writing of test value array (58 registers) to check failure is gone
remove parameter temporary buffer from modbus controller to allow more than 24 byte writes
driver: fix issue with TOUT feature
driver: fix uart_rx_timeout issue
driver: fix issue with rxfifo_tout_int_raw not triggered when received fifo_len = 120 byte and all bytes read out of fifo as result of rxfifo_full_int_raw
driver: add function uart_internal_set_always_rx_timeout() to always handle tout interrupt
examples: call uart_internal_set_always_rx_timeout() to handle tout interrupt correctly
examples: update examples to use tout feature
driver: reflect changes of uart_set_always_rx_timeout() function, change uart.c
driver: change conditions to trigger workaround for tout feature in uart.c
driver: change uart_set_always_rx_timeout()
freemodbus: fix tabs, remove commented code
driver: remove uart_ll_is_rx_idle()
tout_thr - move calculation and masking into hal layer update driver and uart_ll (add uart_ll_set_rx_tout)
move tout calculation into uart_ll
move calculation of time out in bit time for esp32s2 into low level uart_ll.h file
move uart_hal_get_symb_len() into hal
update set_rx_timeout() to warn user about incorrect value
update HAL, LL 1
fix uart_xx_set_rx_tout() to convert symbol time into bit time
update param description
update tout calculation in LL
update uart_hal_get_max_rx_timeout_thrd() and uart_ll_get_max_rx_timeout_thrd()
add support of modbus master ascii
rename base dir name of master and slave example to be mb_slave, mb_master to avoid conflict with sdio/slave example test
add Kconfig option to enable ASCII and RTU mode separately
update ASCII options + remove cast for errors
added baudrate for examples into Kconfig
updated magic numbers for timer timeout
put ascii private definitions into one file
