* Fix analogWrite channel available verification
The last channel allocated is number 0, which conflicted with the value given to an uninitialized pin, giving the "No more analogWrite channels available!" error when trying to use it
Pins are now given the value -1 to indicate that they are not used so channel 0 can be used without errors.
* Fix incorrect array initialization
Keeping array of zeros for `pin_to_channel` and shifting stored channel
values by +1 to keep the pin with channel 0 from being interpreted as unused.

The constants that need to be passed to gpio_matrix_in and gpio_matrix_out
to detach an input or output pin from a peripheral vary by platform. Use
SIG_GPIO_OUT_IDX to detach an output, and GPIO_MATRIX_CONST_ONE_INPUT
and GPIO_MATRIX_CONST_ZERO_INPUT to detach an input. ESP32 before IDF 4.0
didn't define GPIO_MATRIX_CONST_*_INPUT, so add compatibility #defines
for GPIO_FUNC_IN_LOW/HIGH. GPIO_FUNC_IN_LOW/HIGH exist in IDF 4.0+, but
can't be used because they have the wrong values for ESP32-C3 at least
in IDF 4.4.3 (https://github.com/espressif/esp-idf/issues/11737).

* Fix the F_CPU frequency for the ESP32-S3
Hello, I was using the FastLED library and it was complaining about F_CPU not being defined. So, I just noticed that it is not defined for the ESP32-S3 module. So I made this change in the header file and it compiled. Therefore I wanted to propose this change to the HAL library to improve compatibility. Thank you for your time.
* Makes F_CPU generic based on the SoC frequency
Works for ESP32, ESP32C3, ESP32S2, ESP32S3
* Includes ESP32C3 in the F_CPU definition
Necessary for ESP32 Arduino Core 2.0.x based on IDF 4.4

* Remove __FlashStringHelper from ESP32, it's not needed - all the files using it are different from their ESP8266 counterparts anyway.
* Revert removal of class __FlashStringHelper forward for continued compatibility with external libs
* Improved fix, works for libs that return const __FlashStringHelper*
* Inline all wrappers using const __FlashStringHelper*.
WString Fix int64_t
Fixed int64_t String support. Resolves issue #7760.
Background:
sprintf on esp32 doesn't support "%lld" parameter. It's possible to recompile the underlying libraries to add that option, but I have an easier solution.
This has already been solved in ESP8266 version of WString by replacing sprintf() with itoa/ltoa/lltoa.
This PR does the following:
Fixes integer print issues by replacing sprintf() with itoa/ltoa/lltoa
Moves concat(long long num), concat(unsigned long long num) location (match ESP8266)
Cleans up code formatting (matches ESP8266)

* Improve RGB LED Driver
Replaces the use of the `LED_BUILTIN` variable by creating a new variable called `RGB_BUILTIN`. On boards with both a regular LED and RGB LED, this change provides functionality to control either LED.
The `LED_BRIGHTNESS` variable is changed to `RGB_BRIGHTNESS`, which aligns more closely with the `RGB_BUILTIN` variable name.
`BOARD_HAS_NEOPIXEL` is no longer necessary; it is replaced by `RGB_BUILTIN`.
* Update BlinkRGB example
Update example code for changes with the RGB driver:
- Replace `LED_BUILTIN` and `BOARD_HAS_NEOPIXEL` with `RGB_BUILTIN`
- Replace `LED_BRIGHTNESS` with `RGB_BRIGHTNESS`
* Update board variants
Update board variants for changes with the RGB driver:
- Remove `BOARD_HAS_NEOPIXEL`
- Define `RGB_BUILTIN` pin
- Replace `LED_BRIGHTNESS` with `RGB_BRIGHTNESS` to align with `RGB_BUILTIN` name

espressif/esp-idf / components/driver/include/driver/uart.h defines the API:
esp_err_t uart_set_pin(uart_port_t uart_num, int tx_io_num, int rx_io_num, int **rts_io_num**, int **cts_io_num**);
uartSetPins uses that api but alls it with swapped CTS/RTS pins as its API uses a different pin ordering:
uart_set_pin(uart->num, txPin, rxPin, **ctsPin**, **rtsPin**);
This fixes the wrong order in the function uartSetPins

* Changed in pinMode() default intr_type
pins default configuration has intr_type = GPIO_INTR_DISABLE
With this implementation, it will set the intr_type to previously set intr_type. It will no longer disable interrupt, when pinmode is called multiple times on same pin with interrupt enabled.
Description of Change
Fixes IPAddress INADDR_NONE declaration when using Arduino WiFi or ETH.
This symbol was defined as 0xffffffff by lwip /inet.h, making it impossible to use INADDR_NONE correctly.
This PR only works when <wifi-provisioning/wifi_config.h> has a modification to include <lwip/ip4_addr.h> instead of <lwip/inet.h>. This will be done directly to the sdk folder in the github structure and it has been fixed in IDF by a separated Merge Request. This will be reflected in the future, for good.
Tests scenarios
This PR was tested with all Arduino WiFi examples, including AsyncUDP. Also with ETH examples.
It was also tested for #6610 test cases.
Testing done for ESP32, ESP32-S2, ESP32-C3 and ESP32-S3.

* Adds HardwareSerial::onReceiveTimeout()
* Fixed typo
* Changes requested
* Fix eventQueueReset
* Changed _onReceiveTimeout to _rxTimeout for consistency
* Uniform uart_set_rx_timeout condition
* test _uart not NULL in eventQueueReset()
check if _uart is not NULL before using it.
* revert last commit - no need for it
reverting last change made - it is not necessary.
* adds onReceive() parameter
In order to allow the user to choose if onReceive() call back will be called only when UART Rx timeout happens or also when UART FIFO gets 120 bytes,
a new parameter has been added to onReceive() with the default behavior based on timeout.
void onReceive(OnReceiveCb function, bool onlyOnTimeout = true);
onReceive will setup a callback that will be called whenever an UART interruption occurs (UART_INTR_RXFIFO_FULL or UART_INTR_RXFIFO_TOUT)
UART_INTR_RXFIFO_FULL interrupt triggers at UART_FULL_THRESH_DEFAULT bytes received (defined as 120 bytes by default in IDF)
UART_INTR_RXFIFO_TOUT interrupt triggers at UART_TOUT_THRESH_DEFAULT symbols passed without any reception (defined as 10 symbos by default in IDF)
onlyOnTimeout parameter will define how onReceive will behave:
Default: true -- The callback will only be called when RX Timeout happens.
Whole stream of bytes will be ready for being read on the callback function at once.
This option may lead to Rx Overflow depending on the Rx Buffer Size and number of bytes received in the streaming
false -- The callback will be called when FIFO reaches 120 bytes and also on RX Timeout.
The stream of incommig bytes will be "split" into blocks of 120 bytes on each callback.
This option avoid any sort of Rx Overflow, but leaves the UART packet reassembling work to the Application.
* Adds onReceive() parameter for timeout only
* Adds back setRxTimeout()
* Adds setRxTimeout()
* CI Syntax error - "," missing

Summary
Touch Sensor refactoring to be based on IDF 4.4.
Adds support to ESP32S2 and future ESP32S3.
Adds some new APIs:
For all chips:
void touchAttachInterruptArg(uint8_t pin, void (*userFunc)(void*), void *arg, uint32_t threshold);
This function allows the user to add and pass a void* parameter to the ISR user callback.
void touchDetachInterrupt(uint8_t pin);
This function detaches ISR call back for the touch pad pin.
Only ESP32 chip
void touchInterruptSetThresholdDirection(bool mustbeLower);
This function allows the user to set if the ISR callback will be activated when the touch sensor readings are lower or higher than the threshold defined. See example TouchButton.ino.
Only ESP32-S2 and ESP32-S3 chips
bool touchInterruptGetLastStatus(uint8_t pin);
This function reports if the touch pad pin is touched or untouched. It can be used with ISR to identify when it is touched and untouched (released). See example TouchButtonV2.ino.
Impact
None. ll original APIs and examples now run on ESP32 and ESP32-S2.

Summary
This PR fixes an issue with UART1 default pins.
When using pins RX_1 = 18 and TX_1 = 17, UART1 will display a Break Error on those pins when they are floting (not connected).
It also defines RX_2 = 19 and TX_2 = 20 as default pins for UART2.
Impact
The deaulf pins may look different from the original pinout diagram.
I2C Slave currently doesn't compile for projects where Arduino is an IDF component. This adds missing conditionals.

Summary
RMT HAL refactoring based on IDF.
Impact
Improves RMT by adding IDF v4.4 support.

## Summary
Arduino ```setup()``` and ```loop()``` run under a Task with a fixed Stack size of 8KB.
Users may want to change this size.
This PR adds this possibility by just adding a line of code, as for example:
``` dart
ESP_LOOP_TASK_STACK_SIZE(16384);
void setup() {
}
void loop() {
}
```
## Impact
None. It adds a new functionality to ESP32 Arduino.
If ```ESP_LOOP_TASK_STACK_SIZE(newSize);``` is not declared/used, it will compile the sketch with the default stack size of 8KB.

Thanks @igrr for the suggestion!
HardwareSerial flush() was returning before all data was sent out through serial port.
This is a problem to some RS485 libraries that depend on it to signaling.
This PR solves the issue by forcing it to block flush() until all data is sent.
This PR is refactoring of DAC HAL in order to use IDF instead of current Register manipulation approach.
Edited dacWrite() to use ESP-IDF api.
Added dacDisable() so there is an option to disable dac channel.

This pull request contains a few fixes and improvements to the HWCDC implementation.
- Rework `HWCDC::write()` to accept unlimited data
- Add Semaphore to guard the TX Ring Buffer
- Add events support
- Remove unnecessary 1200bps touch for flashing over HWCDC
- Fix `HardwareSerial::setDebugOutput()` not resetting `putc` if the port is already selected, causing debug output to also show on HWCDC even when not selected.
Depending on `tud_cdc_tx_complete_cb` can cause in some cases the last packet to not be transmitted until more data is written and flushed. It's a rare case, but if the other end is expecting those last bytes, transmission will hang.
This PR also fixes debug output on CDC
