A fair bit of reshuffling with include paths and overrides was necessary, as the two RTOS SDKs (ESP8266 and ESP32) don't have the same header structure (or even libraries for that matter). Uses the xtensa-esp108-elf toolchain to build. Completely untested beyond linking, as I still can't flash the ESP32 module I have :( I'd be most surprised if it does anything useful at this point considering I've spent almost no time on the linker script or UART setup. Anything using espconn has been ifdef'd out since espconn is not (and probably will not be) available. Notably this includes the entire net module as well as coap, mqtt and enduser_setup. Many (most?) hardware bus drivers and related modules are also ifdef'd out for now due to hardware differences. Functions surrounding sleep, rtc and RF modes have also been hit by the ifdef hammer. Grep'ing for __ESP8266__ and/or FIXME is a quick way of finding these places. With time I hope all of these will be reinstated.
