On stdio, there's a problem that it shows invalid values for callchains in cumulated hist entries. It's because it only cares about the self period. But with --children behavior, we always add callchain info to the cumulated entries so it should use the value in that case.

This patch automatically adjusts the path of MMAP records associated with Android system libraries. The Android system is organized with system libraries found in /system/lib and user libraries in /data/app-lib. On the host system (not running Android), system libraries can be found in the downloaded NDK directory under ${NDK_ROOT}/platforms/${APP_PLATFORM}/arch-${ARCH}/usr/lib and the user libraries are installed under libs/${APP_ABI} within the apk build directory. This patch makes running the reporting tools possible on the host system using the libraries from the NDK.
