This patch adds the following:

- sources/third_party/googletest/googletest/:
  The sources for the latest GoogleTest revision.

- sources/third_party/googletest/patches.ndk/:
  The patches applied to the upstream sources.

- sources/third_party/googletest/README.NDK:
  Readme file explaining what this is + basic usage instructions.

- sources/third_party/googletest/Android.mk:
  Build file declaring the modules to be imported to use GoogleTest

- tests/device/test-googletest-stlport:
  Simple test to build GoogleTest against STLport and run a few
  sample programs.

- tests/device/test-googletest-gnustl:
  Same as above, but linking against GNU libstdc++.
  This is required because GoogleTest will compile differently
  based on the features of the C++ STL being used (e.g. STLport
  doesn't have <tr1/tuple>)

- tests/device/test-googletest-full:
  The full GoogleTest unit test program (740 tests). Ignored by
  tests/run-tests.sh by default since it's long to build and run.
