Our Air Quality 3c81f7d587 lwip update
* The mdns responder has been reworked to lower stack and memory usage. This is
  a variation on the upstream code, it use malloc whereas the upstream code uses
  pools. The high stack usage of the mdns responder was problem for
  esp-open-rtos, so we might have to maintain the differences for now.

* Improved lwip core locking, and lock checking. Upstream improvements, that
  need some added support from esp-open-rtos specific code. More core lock is
  performed when calling from the esp-open-rtos code now, so a little safer. The
  checking is not enforced, but projects might see warning messages and might
  want to look into them.

* The esp-open-rtos lwip support has been sync'ed with the new freertos port
  included with lwip. There are still some minor differences.

* A few lwip timer bugs have been resolved. This might help resolve some issues.

* Plus it picks up all the other upstream fixes and improvements.

* The default lwip stack has been lowered from 768 words to 480 words,
  due to the reduced stack usage by the mdns responder.

Open Espressif Libs

These are functional recreations of the MIT licensed binary Espressif SDK libraries found in lib. They keep the same functionality as the SDK libraries (possibly with bugfixes or other minor tweaks), but are compiled from source.

Most of the reverse engineering work so far has been by Alex Stewart (@foogod).

See http://esp8266-re.foogod.com/wiki/ for more technical details of SDK library internals.

Disabling

The open ESP libs are compiled in by default, and they automatically replace any binary SDK symbols (functions, etc.) with the same names.

To compile using the binary SDK libraries only, override the COMPONENTS list in parameters.mk to remove the open_esplibs component, or add -DOPEN_ESPLIBS=0 to CPPFLAGS.

To selectively replace some functionality with binary SDK functionality for debugging, edit the header file open_esplibs/include/open_esplibs.h
