lwip lib bundled with esp32 Arduino supports only one ntp server. Any additional servers set are just silently ignored.
This default is different from esp8266 Arduino core and very confusing. Most of the examples provided uses 3 different ntp servers for redundancy while only the first one is used actually.
Addressing issue #4964
* Update boards.txt
Add menu items for ffat on mhetesp32minikit board.
* Add partition table.
* Added ffat partition for 4MB ESP32 Dev Module.
* Added comment about partitioning schemes.
* First commit of FFat library
* Fixed reboot loops if no fat present. Added CMakeLists
* Functionalize the partition checks
* Cleanup, especially in format
* Dont format if mounted. More wording cleanup
* 16M ffat should only be on 16M board
* Fix some casting issues that trip up the compiler when building as ESP-IDF component
