Note that this is for bionic headers to be consistent with 64-bit headers tentatively placed at android-20. ie. 1. bionic headers in all the existing 32-bit headers android-3 .. 19 are consistent, and don't track any new development in bionic/ since JB (the time when significant refactoring work starts in bionic/) unless bug fixes. 2. bionic headers in android-20 tracks bionic/ Change-Id: Ia07f04ac03ffaef6a6ddcea5f0e6b891e21a869a
