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
* BLE and softAP provisioning examples added along with tests.
* An application specific example added for demonstrating custom provisioning scheme.
* tools/esp_prov/esp_prov.py can be used as a provisioning client for SoftAP, BLE and CLI based transports.

set shorter time to save some space on server. For those artifacts need
to be stored for long time, we can manually press "keep" button in job page.
Also add a CI job to check if all artifacts have set expire time.
Changes:
KConfig: The option CONFIG_ESP32_RTCDATA_IN_FAST_MEM is added in Kconfig file for esp32 component.
esp32.common.ld: added support of RTC_DATA_ATTR, RTC_RODATA_ATTR data placement into appropriate segment according to Kconfig option.
esp32.ld: linker script is modified to set alias for memory segment selected by Kconfig option to place data. The segments for force placement are added for RTC_FAST_ATTR, RTC_SLOW_ATTR attributes.
esp_attr.h: added new attributes RTC_FAST_ATTR, RTC_SLOW_ATTR for force placement into fest/slow memory.
test_rtc_fast.c: Added unit test cases to check data placement into appropriate memory segment.
Updated documentation for RTC_DATA_ATTR, RTC_FAST_ATTR, RTC_SLOW_ATTR in deep_sleep_stub.rst file.

Currently CI test environment is complicated, usually includes NIC, AP.
These devices are not used for a lot test cases. Therefore we split the
test environment, remove unnecessary devices. Then it will be easier to
create CI runners.
1. New tests for SD card on slot 0. Currently frequency for 4-bit mode
has to be reduced in the test.
2. Change pin for CD/WP tests, re-enable CD tests.
1. Add the 100 times test when the private key is generated by the random number;
2. Add the bt components to the unit-test-app/config directory.
3. Added the bt unit test case to CI.
An existing UART driver does not support RS485 half duplex mode.
This task adds this functionality to ESP_IDF UART driver.
driver/uart.c/h: updated to add support of RS485 half duplex mode
examples/peripherals/uart_echo_rs485/main/rs485_example.c: added test example
components/driver/test/test_uart.c: added test of RS485 half duplex mode
docs/en/api-reference/peripherals/uart.rst: updated documentation
test_uart.c: suppress GCC warnings about discarded const qualifiers
uart.rst: remove sphinx warning - "Duplicate explicit target name"
simple change in uart.h file
update (test_uart.c) after rebase from master
update uart.rst, uart.c, rs485_example.c
Update example description in file Readme.md
update uart.c/h, uart.rst, test_uart.c according to review results
update uart.h (uart_set_rx_timeout() description
test_uart.c remove ignore tag
The tests are completed using RS485 adapters hardware connected to two ESP32 WROVER KITs.
