* Update IDF to v3.2 977854975

* Update app_httpd.cpp

fixes: https://github.com/espressif/arduino-esp32/issues/2758

* Converted EEPROM library to use nvs instead of partition.  Removed eeprom partition from all partition table CSV files.
* Changed variable names, added some comments, formatting as per me-no-dev's requests
* Checks for memory on malloc
* Moved include nvs.h from header to code
* Reworked the extra example to make it more clear how to actually use the library and persist data

* Set IDF to v3.2

* Remove BLE submodule

* Add BLE lib source

* Update Camera example to support OV3660

* Added 2 ffat partition schemes for 4MB modules + improved descriptions.

Existing format options were unclear on how much spiffs you were
getting. Also add missing 1MB App/3MB Spiffs split.
This addresses https://github.com/espressif/arduino-esp32/issues/1799

This makes it very clear what each option gives you, and also adds 2 options
to get ffat on 4MB chips..

* Added link to ffat howto.

* 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.

- ESP-Face to 2937054
- ESP32-Camera to 113629b

Adding the -g3 flag that was omitted in the PIO build script but is present in Arduino IDE build scripts. This flag restores the ability to get line numbers from stack traces for elf files generated in PlatformIO IDE.
