Remove all duplicate platform files, i.e development/ndk/platforms/android-N now only contains files that are introduced in API level 'N' and not found in level 'N-1' (This makes it easier to manage independent platform release branches, and makes platform additions trivial to examine and maintain). Move samples that depends on features of API level 'N' into platforms/android-N/samples + update tests/run-all.sh accordingly Change-Id: I04c4c67c6c674c1714d5812d461d0524a4f4cfd9
