* reorder fn in can.md, remove driver_can/Kconfig
* fixed a leak when can.stop()
- 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.
This fixes the panic-on-restart issue and the crash-on-uart-input-before-flash-mapped issue.
Node module updated to reflect new function names for sleep/restart.
WiFi STA module updated to reflect IDF name changes.
Platform flash and partition api updated to reflect IDF name changes.
Eventually these (and the SPIFFS module) will likely need to be updated
to exclusively work with the esp_partition_xxx() functions in order to
support working with encrypted flash.
Based on his revision 2d290a24a0914be88e5ca4ac7b1018392fe75fe2
(https://github.com/djphoenix/nodemcu-firmware).
All LWIP callback handling changed to use the NodeMCU task interface
to make it usable on RTOS.
IPv4 assumptions have been removed, and this net module /should/ now
be IPv6 ready, but aside from compilation no testing has been done
in this area.
SSL integration points not touched - some work needed there once we
have an mbedTLS module.
