wait4() was incorrectly declared in <sys/wait.h>, but only added to the
C library in Android 4.3 (API level 18) [1]
This patch:
- Removes the wait4() declarations for any <sys/wait.h> header before
API level 19.
- Brings the API level 19 <sys/wait.h> which correctly declares wait4().
- Update the libc.so.functions.txt for API level 19 of all platforms
to include the exported symbol.
NOTE: This does not bring the static libc.a to API level 19, which means
it is stuck at API level 9 for ARM.
See [2] for the corresponding NDK tests.

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

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.
