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

This introduces crtbegin_so.o and crtend_so.o and also requires a corresponding
change in the NDK build scripts to use them.
Also add a small test under 'tests/dlclose-destruction' to check that.
Note that this is not a sample (i.e. Android application) per se.
