* Small grammar fixes and clarifications
Just fixed some small grammar issues in the comments and clarified a few things that might seem confusing.
* More spelling fixes that I introduced...
* Update mDNS and LEDC
* update toolchain
* Update IDF to 1c3dd23
* Advertise the board variant for Arduino OTA
* Add generic variant definition for mDNS
* Allow configuration of Ethernet PHY clock source
Refer to https://github.com/espressif/esp-idf/pull/1127
The internal APLL can be used to generate the 50MHz clock for the internal EMAC and the external Ethernet PHY.
The clock can either be input on GPIO0 (as before) or output on GPIO0, GPIO16 or GPIO17 (only GPIO17 extensively tested).
New example available.

When user selected HSPI with SPIClass name(HSPI) ESP was, by default,
still using VSPI ports (the ones defined in pins_arduino.h).
With this change when user selects HSPI then HSPI default ports will be
used.
If user won't specify HSPI then VSPI default ports will be used.
If user will specify SCLK, MOSI, MISO and SS with SPI.begin() then user
defined ports will be used no matter if VSPI or HSPI is selected.
With this change fe. SD library can use default HSPI ports. It was
possible to
pass HSPI SPI instance to SD lib, however even then it was using VSPI
ports which were (probably) GPIO matrixed to HSPI.
The .build.board=xx proptery is used for generating a macro named "ARDUINO_xxx".
C macro names should never have a "-" sign.
* current: ARDUINO_NodeMCU-32S
* should be: ARDUINO_=NodeMCU_32S
* fix NodeMCU-32S .build.board property

`-DARDUINO_BOARD={build.board}` **is missing**
* Revert "fix NodeMCU-32S .build.board property"
This reverts commit ea57b1496a2e87d3977a31a29a4cf7d63216f008.
* ArduinoOTA would stop receiving any packets if the port received a zero-length UDP packet, commonly sent by network scanners like nmap. Fixed to flush() after every call to parsePacket(), even if read length is 0.
Additionally, added length checking to fix a potential buffer overflow in parseInt().
Finally, added an end() method that stops the OTA listener and releases resources.
* Only end MDNS in end() if mdns mode is enabled.
