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.
