1. WiFiProv.ino sketch is added that allows arduino users to do provisioning via SoftAP or BLE. WiFi.beginProvision( ) API is designed for provisioning in Arduino.
2. In WiFiProv.h provisioning class is defined.
3. WiFiProv.cpp contains implementation for provisioning class.
4. README.md file is added which contains detail information for working.
The boundary delimiter (_STREAM_BOUNDARY) needs to be send before the
body part (_STREAM_PART) too follow RFC2046. This caused ffplay/ffmpeg
to fail to open the MJPEG stream.
* std::shared_ptr Memory Leak
clientSocketHande and _rxBuffer are std::shared_ptr, the stop() call was not correctly releasing them and the operator= had similar problems fix for #3679
* operator= second attempt
* operator= third time
* Minimize HardwareSerial Receive and Transmit delays
* Remove uartRxFifoToQueue from esp-hal-uart.h

* fix removeApbChangeCallback() error in spiStopBus()
spiStartBus() was using spiStopBus() to init the hardware, one of spiStopBus() functions is to unregister the runtime CPU clock speed change callback. But, spiStartBus() only wanted to init the hardware. This patch separates the hardware init into a standalone function spiInitBus() that both spiStartBus() and spiStopBus() call.
* Update esp32-hal-spi.c
capitalization problem
WiFiClient.connected() was hanging thinking there was still a connection when the remote had already closed. The one-liner in this patch addresses recv() returning 0 and errno==128. I couldn't find the corresponding errno for 128 but its caught by the case statement which includes EPIPE, ENOTCONN, ECONNRESET and ECONNABORTED so I assume its one of those. Broken pipe maybe?
```c
[D][WiFiClient.cpp:511] connected(): Disconnected: RES: 0, ERR: 128
```
EDIT: added comment to reflect that recv() can set errno when it returns 0.
* Fix flush
flush should not flush the read buffer, it should wait till all output is drained from the write buffer.
* Update BluetoothSerial.cpp

fixed the connected() function so that it only checks errno if recv returns a value of -1.
"in the even of an error, errno is set to indicate the error" --manpage
This fixes the ESP32 Webserver when dealing with a modern webserver with a slow SD card.
* API compatibility to AVR, ESP8266, et al
* Add non-blocking HardwareSerial::read(buffer, size) extension (ESP8266 portability)
* Refactor for fewer indirect calls.
* Updated BLERemoteCharacteristic to exposre esp_gatt_auth_req_t parameter for readValue and writeValue.
* Updated BLERemoteCharacteristic/Descriptor to expose a setAuth method to allow tweaking the authentication request type for that remotecharacteristic/descriptor without the need to add auth on each read/write.
