/*
   A bit of explanation for this entry point:

   SYS is the SDK task/context used by the upperlying system to run its
   administrative tasks (at least WLAN and lwip's receive callbacks and
   Ticker).  NONOS-SDK is designed to run user's non-threaded code in
   another specific task/context with its own stack in BSS.

   Some clever fellows found that the SYS stack was a large and quite unused
   piece of ram that we could use for the user's stack instead of using user's
   main memory, thus saving around 4KB on ram/heap.

   A problem arose later, which is that this stack can heavily be used by
   the SDK for some features.  One of these features is WPS.  We still don't
   know if other features are using this, or if this memory is going to be
   used in future SDK releases.

   WPS beeing flawed by its poor security, or not beeing used by lots of
   users, it has been decided that we are still going to use that memory for
   user's stack and disable the use of WPS.

   app_entry() jumps to app_entry_custom() defined as "weakref" calling
   itself a weak customizable function, allowing to use another one when
   this is required (see core_esp8266_app_entry_noextra4k.cpp, used by WPS).

   (note: setting app_entry() itself as "weak" is not sufficient and always
    ends up with the other "noextra4k" one linked, maybe because it has a
    default ENTRY(app_entry) value in linker scripts).
