Automatic stack location selection (SYS or HEAP), enable per library AR-chive in arduino build system 

* enable dot_a_linkage on internal libraries
* add device tests
* boards generator: deprecate --noextra4k/--allowWPS and fix documentation

* increase available flash space by disabling floats in ``*printf`` functions
* enable WPS which is now disabled by default (at the cost of a smaller heap by ~4KB)
* change led pin ``LED_BUILTIN`` for the two generic boards
* change the default lwIP version (1.4 or 2)

* Using ``*printf()`` with floats is enabled by default. Some KBs of flash can
be saved by using the option ``--nofloat`` with the boards generator:
``./tools/boards.txt.py --nofloat --allgen``
``./tools/boards.txt.py --nofloat --boardsgen``
* Use the debug level option ``NoAssert-NDEBUG`` (in the Tools menu)

Why can't I use WPS ?
~~~~~~~~~~~~~~~~~~~~~
About WPS
~~~~~~~~~
WPS is disabled by default, this offers an extra 4KB in ram/heap. To enable
WPS (and lose 4KB of useable ram), use this boards generator option:
From release 2.4.2 and ahead, not using WPS will give an exra ~4.5KB in
heap.
``./tools/boards.txt.py --allowWPS --allgen``
In release 2.4.2 only, WPS is disabled by default and the board generator is
required to enable it:
``./tools/boards.txt.py --allowWPS --boardsgen``
`Read more <a05-board-generator.rst>`__.
This manual selection is not needed starting from 2.5.0 (and in git
version). WPS is always available, and not using it will give an extra
~4.5KB compared to releases until 2.4.1 included.
This Arduino library doesn't work on ESP. How do I make it work?
