With the IDF asserting full control over the linker scripts and insisting on the application description being the first entry in the .flash.rodata section, or previous method of doing link-time arrays stopped working. Why? Because the build patched in a SHA256 digest straight into our arrays. With the limited language of the gcc linker scripts I could find no other way of getting it in cleanly. The IDF "linker fragments" support can not be made to work for our needs: - no support for setting alignment before including objects - no support for declaring symbols - no support for adding our terminating zeros - insists on grouping objects by lib rather than by declared grouping, which means we could at most have a single link-time-array using the IDF mechanism - also does not like underscores in section names, but that's just an annoyance So, the least bad option that I could come up with was to use a project-wide makefile snippet to add a target in-between the IDF's generation of the esp32.project.ld file, and the linking of our NodeMCU.elf. In this target we read in the esp32.project.ld linker script, check whether we have our arrays in there, and if not rewrites the linker script. Oh, and the esp32.project.ld file only came into existence on the IDF 3.3 branch, so I had to change up the IDF to the latest release/3.3 as well. I would've preferred a stable tag, but the v3.3-beta3 had a really nasty regression for us (can't add partition entry), so that was a no-go.

- Switched hardcoded interrupts to new IDF interrupt allocation framework. - gpio module switched to the IDF's per-pin interrupt callback service. - Improved NodeMCU linker script since it broke with the IDF upgrade. - Various compatibility updates.

Modules can now subscribe to ESP system events via the new NODEMCU_ESP_EVENT() macro. See nodemcu_esp_event.h for details.

RTOS driver evicted as it did not play nice with stdio etc. Implemented a minimal driver to fully support Lua console on UART0. Output on UART0 done via stdout (provided by the IDF). Input and setup handled via driver_console/console.c. In addition to the direct input function console_getc(), the driver also registers in the syscall tables to enable regular stdio input functions to work (yay!). The Lua VM is still using the direct interface since it's less overhead, but does also work when going through stdin/fd 0. Auto-bauding on the console is not yet functional; revisit when the UART docs are available. Module registration/linking/enabling moved over to be Kconfig based. See updates to base_nodemcu/include/module.h and base_nodemcu/Kconfig for details. The sdk-overrides directory/approach is no longer used. The IDF is simply too different to the old RTOS SDK - we need to adapt our code directly instead. Everything in app/ is now unused, and will need to be gradually migrated into components/ though it is probably better to migrate straight from the latest dev branch.
