ext: Build googlemock with googletest

googlemock needs to be built together with googletest. This patch
is enabling it by doing the following things

* Moving googletest and googlemock under the same top level directory,
  so that we have a single SConscript for building them.
  This also matches googletest directory structure:
  googletest
      |_googletest
      |_googlemock

* Adding a shared SConscript which is building gmock and gtest as libgtest
* Removing googletest/SConscript

-Changes for 1.7.0:
-
-* New feature: death tests are supported on OpenBSD and in iOS
-  simulator now.
-* New feature: Google Test now implements a protocol to allow
-  a test runner to detect that a test program has exited
-  prematurely and report it as a failure (before it would be
-  falsely reported as a success if the exit code is 0).
-* New feature: Test::RecordProperty() can now be used outside of the
-  lifespan of a test method, in which case it will be attributed to
-  the current test case or the test program in the XML report.
-* New feature (potentially breaking): --gtest_list_tests now prints
-  the type parameters and value parameters for each test.
-* Improvement: char pointers and char arrays are now escaped properly
-  in failure messages.
-* Improvement: failure summary in XML reports now includes file and
-  line information.
-* Improvement: the <testsuites> XML element now has a timestamp attribute.
-* Improvement: When --gtest_filter is specified, XML report now doesn't
-  contain information about tests that are filtered out.
-* Fixed the bug where long --gtest_filter flag values are truncated in
-  death tests.
-* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
-  function instead of a macro in order to work better with Clang.
-* Compatibility fixes with C++ 11 and various platforms.
-* Bug/warning fixes.
-
-Changes for 1.6.0:
-
-* New feature: ADD_FAILURE_AT() for reporting a test failure at the
-  given source location -- useful for writing testing utilities.
-* New feature: the universal value printer is moved from Google Mock
-  to Google Test.
-* New feature: type parameters and value parameters are reported in
-  the XML report now.
-* A gtest_disable_pthreads CMake option.
-* Colored output works in GNU Screen sessions now.
-* Parameters of value-parameterized tests are now printed in the
-  textual output.
-* Failures from ad hoc test assertions run before RUN_ALL_TESTS() are
-  now correctly reported.
-* Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to
-  ostream.
-* More complete handling of exceptions.
-* GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter
-  name is already used by another library.
-* --gtest_catch_exceptions is now true by default, allowing a test
-  program to continue after an exception is thrown.
-* Value-parameterized test fixtures can now derive from Test and
-  WithParamInterface<T> separately, easing conversion of legacy tests.
-* Death test messages are clearly marked to make them more
-  distinguishable from other messages.
-* Compatibility fixes for Android, Google Native Client, MinGW, HP UX,
-  PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear),
-  IBM XL C++ (Visual Age C++), and C++0x.
-* Bug fixes and implementation clean-ups.
-* Potentially incompatible changes: disables the harmful 'make install'
-  command in autotools.
-
-Changes for 1.5.0:
-
- * New feature: assertions can be safely called in multiple threads
-   where the pthreads library is available.
- * New feature: predicates used inside EXPECT_TRUE() and friends
-   can now generate custom failure messages.
- * New feature: Google Test can now be compiled as a DLL.
- * New feature: fused source files are included.
- * New feature: prints help when encountering unrecognized Google Test flags.
- * Experimental feature: CMake build script (requires CMake 2.6.4+).
- * Experimental feature: the Pump script for meta programming.
- * double values streamed to an assertion are printed with enough precision
-   to differentiate any two different values.
- * Google Test now works on Solaris and AIX.
- * Build and test script improvements.
- * Bug fixes and implementation clean-ups.
-
- Potentially breaking changes:
-
- * Stopped supporting VC++ 7.1 with exceptions disabled.
- * Dropped support for 'make install'.
-
-Changes for 1.4.0:
-
- * New feature: the event listener API
- * New feature: test shuffling
- * New feature: the XML report format is closer to junitreport and can
-   be parsed by Hudson now.
- * New feature: when a test runs under Visual Studio, its failures are
-   integrated in the IDE.
- * New feature: /MD(d) versions of VC++ projects.
- * New feature: elapsed time for the tests is printed by default.
- * New feature: comes with a TR1 tuple implementation such that Boost
-   is no longer needed for Combine().
- * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends.
- * New feature: the Xcode project can now produce static gtest
-   libraries in addition to a framework.
- * Compatibility fixes for Solaris, Cygwin, minGW, Windows Mobile,
-   Symbian, gcc, and C++Builder.

-   .cc file for easy deployment.

-   machines (requires support from the test runner).
- * Bug fixes and implementation clean-ups.
