* 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.

I have kept the original APPS size on purpose as 40KB SPIFFS is useless IMHO

Some fixes to nghttp2 to provide basic functionality. Added the missing main header. Removed the asio headers which require Boost libraries. Moved http_parser into the expected location. (#2068)

* 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

Because TCP is stream-based, an earlier read can 'take away' the "OK" response
from the device, so that a later read doesn't get the message.

* script exec fails on curl error

* Add PSRAM init and malloc funtions

* Rebuild IDF libs
