* Added baudrate detection to esp32-hal-uart and HardwareSerial

* Solved compiler warning for uartResizeRxBuffer()

* Add unit to header variable name (timeout_ms)

* Reverting accidentally changed files to master

* Add small delay after baudrate detection

Pin definitions T8/T9 & DAC1/DAC2 Back To Front (Issue #1831)

Pin definitions T8/T9 & DAC1/DAC2 Back To Front

* make WiFi.softAP() more robust

* WiFi.softAP() revert fallback to WIFI_AUTH_OPEN

fixes #1875

Incorrect values used, use the proper defines from header-files instead.

* removed uint8_t Wire.endTransmission(uint8_t sendStop)

Having both endTransmission(bool) and endTransmission(uint8_t) creates problems.
There is no need for endTransmission(uint8_t)
endTransmission(1) and endTransmission(0) works with endTransmission(bool).
Removing endTransmission(uint8_t) allows the ESP32 code to be compatible with
all the other Arduino cores by allowing endTransmission(1) and endTranmission(0)
to work as it does on all the other cores.

* Wire library version bump for endTransmission() update

#1869 exposed a resource exhaustion issue. The current HAL layer for I2C support is designed to use a shared interrupt, But, during debugging to solve the interrupt overloading condition identified in #1588, and the generation of pr #1717, the interrupt allocation parameters were changed.  This change was unnecessary, the code will work successfully with shared interrupts.  So, there is no need to assign a private interrupt for each I2C peripheral.

* Add BPI-BIT boards connfig

* Add BPI-BIT v1.3 boards

* Add wESP32 support

* Add default Ethernet config

Few testers let me know, they were unable with connection to Eduroam network under PEAP+MsCHAPv2 methods.
They were trying many modifications. Solution is very absurd. 
Change board to STA mode manually. 
One tester from Italy was able to connect to Eduroam network under TTLS + MsCHAPv2 with that sketch too!

Sketch was tested and worked almost for all testers with that problem.

fixes #1734

* Add delay into example to allow print before sleep

* Changed to Serial.flush()

see #1800

(removed quotes from last line, and fixed indentation, no text changes)

Add functionality allowing rxBuffer of HardwareSerial to be changed in size via HardwareSerial::setRxBufferSize. (#1855)

* Updated ISSUE_TEMPLATE to try to get better postings

* Added line for PSRAM enabled

* More complete info request as per @stickbreaker

- Delete queue at end
- Close BT connection before end
- DeInit SPP

The original pins_arduino.h did not correspond to the actual hardware.

If the esp32 is reset during a i2c read cycle the slave device may be in control of the SDA line.  

If the SDA line is held low, the esp32 cannot issue a START or STOP to recover the bus. 

The previous code did not correctly configure the SCL output pin, and it cycled SCL 9 times with SDA Low.  Since the slave device was in a READ cycle, it just continued outputting the bits of the current byte.  When the ACK/NAK bit space occurred, The low output value of SDA was interpreted as ACK so the slave device continued with the next byte.  It never terminated the READ cycle. 

This new code will correctly recover from an interrupted READ
