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.

This reverts commit b2c67887.

* 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.

Number of pulses is limited to the reserved RMT memory for the channel. Very useful for PWM, Servo and other repeatable signals.

Fix recent commit d8b20984 (PR #3377) which includes esp_adc_cal component but does not update CMakeLists.txt (#3648)

The default value is 0 (= all channels) to preserve backward compatibility.

* add board HONEYLemon

Extend BLEDevice::setPower() to include powerType parameter. It's optional and set to ESP_BLE_PWR_TYPE_DEFAULT for compatibility. (#3623)

Extend BLEDevice::setPower() to include powerType parameter. It's optional and set to ESP_BLE_PWR_TYPE_DEFAULT for compatibility.

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.

add the partition and flash size menus for the VintLabs board definitions.

Fixed incorrect board name for TinyPICO - You can now use this to detect it's a TinyPICO at compile time.... (#3567)

#ifdef ARDUINO_TINYPICO
   // It's a TinyPICO!
#endif

Added two boards from iarduino.ru based on ESP-32

Small change to insure wifi starts off and avoid crashing

* API compatibility to AVR, ESP8266, et al

* Add non-blocking HardwareSerial::read(buffer, size) extension (ESP8266 portability)

* Refactor for fewer indirect calls.

Currently we have no way to set BLE Advertisement Type.
We have an initial value of ADV_TYPE_IND and the member is private.

iBeacon should advertise with ADV_TYPE_NONCONN_IND.
esp-idf's example code specifies this value.

https://github.com/espressif/esp-idf/blob/93a8603c545fb8e54741d6685146e2f3b874378d/examples/bluetooth/bluedroid/ble/ble_ibeacon/main/ibeacon_demo.c#L57

* 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.

`WIFI_REASON_CONNECTION_FAIL` has been added to `wifi_err_reason_t` some time ago:  
https://github.com/espressif/arduino-esp32/blob/cec3fca4ad4a39feb463f9298ab3238819732d50/tools/sdk/include/esp32/esp_wifi_types.h#L95

But it was still missing from `system_event_reasons` in `WiFiGeneric.cpp` sometimes causing panics here:  
https://github.com/espressif/arduino-esp32/blob/cec3fca4ad4a39feb463f9298ab3238819732d50/libraries/WiFi/src/WiFiGeneric.cpp#L348

* Utilize prepoc symbols for SPI pins
* Adjusts for GPIO pins when ALTERNATE_PINS is set

Added pinout for TTGO T Journal device and improved the intent of comments.

With the >= used let's say you have four RMT inputs, each using 2 channels wide for their receive buffer. This is 4*2 = 8 buffers which is the number of hardware buffers (MAX_CHANNELS). But, for the fourth input the starting buffer will be 6 (this is correct, the buffers used for each input are 0-1, 2-3, 4-5, 6-7). But, 6+2 = 8 which  is MAX_CHANNELS. This is valid but the >= would match against it and abort. It is correct to only abort if the value i+j is only greater than MAX_CHANNELS. Thus, a simple one character fix. Delete the equals sign.

* BLE: reception support multiple service data

* fix prev commit, i not inicialized

* WString explicit converters to reduce Flash size

This is a port from the same patch for ESP8266: https://github.com/esp8266/Arduino/pull/6759/files

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.

Hi,

I have added a variant for the LilyGo TTGO LoRa32-OLED V2, which is similar to the LilyGo TTGO LoRa32-OLED V1 but with a different pinout. This will be useful for PlatformIO users, specially because I am also adding the board there as well.

Cheers.

* Add Uri with support for staticUri, regexUri and globUri

* Add newline to end of files

* Update example

* Suppress gcc warnings (unused params)
