From 5eafdf0f9bfd9a3c5f93414ac16bb399b6da0b7f Mon Sep 17 00:00:00 2001
From: Chih-Hung Hsieh <chh@google.com>
Date: Thu, 24 Sep 2015 15:42:30 -0700
Subject: Move files up to match upstream source structure.

To create an upstream-master branch later and keep track
of upstream changes.
* src/Android.mk file is deleted because ./Android.mk
  is identical and serves the same purpose.
* ./Makefile.am is moved from old src/Makefile.am,
  and new src/Makefile.am is from old src/src/Makefile.am.
  Similarly, ./ChangeLog is moved from old src/ChangeLog,
  and new src/ChangeLog is from old src/src/ChangeLog.
* Remove unnecessary files that were generated by
  autoconf or configure.

Change-Id: Iafc67d1e80f9d7ad2a74bc851bf9ca9e87205336
