dist/tools/compile_and_test_for_board: add compile and test script

dist/tools/compile_and_test_for_board/README.md

+Compile and Test one board
+==========================
+
+
+The `./compile_and_test_for_board.py` script can be used to run all compilation
+and **automated** tests for one board, not the manual tests.
+
+
+Usage
+-----
+
+    ./compile_and_test_for_board.py path_to_riot_directory board_name [results]
+
+It prints the summary with results files relative to `results_dir/board` to have
+a github friendly output.
+
+Failures and all tests output are saved in files.
+They can be checked with:
+
+    find results/ -name '*.failed'
+    find results/ -name 'test.success'
+
+
+Implementation TODO
+-------------------
+
+The script was developed for being used outside of RIOT so does not currently
+simply adapt to be used from within RIOT.
+
+* Provide another script for new interface?
+* Provide a RIOT/Makefile integration
+* Save output files into `${BUILD_DIR}/output/compile_and_test` directory by
+  default
+* tox file to run `doctests/pylint/flake8`. Add tests.
+* Implement the `board_is_supported`/`board_has_enough_memory`/`has_tests` to
+  make targets instead of fiddling to get the value
