## 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!

Fixes: https://github.com/espressif/arduino-esp32/issues/6019

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.

* Refactoring function headers

Changing the header so the main TwoWire::requestFrom() definition uses a `size_t` instead of a `uint8_t`, removing the 255 bytes limit on I2C requests.

* using ksz8081 only from ESP-IDF 4.4 onwards

The previous assertion only considerate the existance of ESP-IDF 4.3, but with the ESP-IDF 4.3.1 release this assertion would generate errors. Now only includes from ESP-IDF 4.4 onwards.

Migrate MD5Builder to use esp_rom functions directly rather than rely on wrappers that can be omitted from compilation based on sdkconfig. (#5941)

- supports the WiFi/Ethernet board with WT32-S1 module and LAN8720A Ethernet PHY
- documentation available at http://www.wireless-tag.com/portfolio/wt32-eth01/

Current implementation clears _headers when request was sent. If the
user added custom request headers, they will be lost and the redirected
request will not contain them. This commit changes the scope of cleanup
so that the headers survive redirects but don't survive connection
reuse.

1.0.6 changed scanning method to always scan all available channels during connect. This results in results in connect taking about ~3 seconds instead of ~1. This patch changes the behavior to use WIFI_FAST_SCAN if client used a specific channel.

* Merged all TTGO-LoRa32 Board profiles (see #5933)

* Fix for LORA_RST (see #5966)

* [Feature] Added Sonoff DUALR3 support with RainMaker example

* [Feature] Added skip files for C3 and S2
