ndk: Fix <sys/atomics.h> declarations. The atomic operations exported by the platform's C library do not provide full memory barriers. This can result in incorrect results when NDK machine code linked against them runs on multi-core devices. While the bug has been fixed in the platform, this NDK header change ensures that any source code that includes <sys/atomics.h> will end up using a correct implementation of these functions, based on the corresponding GCC builtins. These builtins always provide a full barrier and have reasonable performance. Application developers who depend on <sys/atomics.h> should recompile their unmodified sources against this version of the NDK as soon as possible.

Unify NDK platform headers. This commit removes duplication of system headers per platform, i.e. remove copies of common headers like <stdlib.h> from arch-arm/usr/include and arch-x86/usr/include and move them to a common include directory. More specifically: - common headers: android-N/arch-A/usr/include --> android-N/include - arch-specific headers: android-N/arch-A/usr-include --> android-N/arch-A/include - arch-specific libs: android-N/arch-A/usr/lib --> android-N/arch-A/lib Change-Id: Ifdba5038d108901931f3e3a7c14ebe6270d2d276 NOTE: This also contains careful separation of API-level-specific headers. For example, platforms/android-5/include/pthread.h contains new function declarations that are not available when using platforms/android-3/include/pthread.h NOTE: The NDK's build-platforms.sh script has been updated to understand the new layout. This change in develeopment/ndk does not change the layout of platform files under $NDK/platforms after build-platforms.sh is called.
