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
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.
* 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.
If two headers with overlapping names are added while replace == true, like in:
```cpp
http.addHeader("api_token", "pMXFOLpinQqajaRQJYMeWObg2XYmcX1");
http.addHeader("token", "1234");
```
then replacing went wrong. This is fixed with this PR.
This event name was missing in the list:
d5e2bb12ca/tools/sdk/include/esp32/esp_event_legacy.h (L43)
E.g., it was giving
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 24 - ETH_GOT_IP
When it should have been
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 24 - ETH_DISCONNECTED
Especially if the user wants to use the library as component in IDF,
there are some pitfalls while doing make menuconfig. One is this missing
dependency which will now fail with a better error message with a hint to
the user how to fix it.

This changes all SPI functions that take data pointers which are
not modified so that the declaration is const. This allows them
to be used with const data (i.e. held in flash). No functional
changes are required.
The defnitions of spiWrite() and spiTransferBytes() in
esp-hal-spi.h/c have been updated to be consistent.
Tests:
- Build a simple sketch using SPI.writePattern() and
SPI.transferBytes() which uses const data and verify that the
attached device functions as expected.
