Updated gMock to 1.7.0

This change updates gMock to the new release, 1.7.0.  This is
necessary for Android, as Android Master has updated their gTest to
1.7.0, and we must always use the matching version of gMock.

This should not break any existing tests, as 1.7.0 is
backwards-compatible with 1.6.0 code in nearly all cases.  There are
a few bugfixes around being too generous with type coercion in
EXPECT_THAT() and ASSERT_THAT() that could break code that was
accepted by the compiler before but was never technically safe.

For a full list of changes, including all the awesome new matchers
you can now use in your tests, see CHANGES, which is included from
gMock unchanged.

For a full list of modifications made to allow this to work on
Android Master, see the updated README.android.

No changes to the GYP files were necessary as part of this upgrade.
