Upgrade gtest to r267 and gmock to r173.

testing/README.chromium

 We include a snapshot of gmock from http://googlemock.googlecode.com/svn/trunk
 with chromium.patch applied.

 -- HOW TO USE --
 
 If you are unfamiliar with gmock, there is an example of how to write a test
 based on gmock in base/gmock_unittest.cc.  To use gmock, just add a dependency
 onto testing/gmock.gyp:gmock in your gyp target.
 
 For more general informaiton, there is a lot of good documentation availble on
 the googlemock website:
 
   http://code.google.com/p/googlemock/
 
 In particular, the "For Dummies" guide is a good place to start.  The
 "CheatSheet" and "CookBook" are better as references.
 
 
 -- RECREATING PACKAGE --
 
-Gmock requires tr1 tuple.  However, Visual Studio 2005 does not include
-tr1 tuple, so a version of boost tuple was added into the third_party
-tree for chromium.  Our version of gmock has been patched to search for
-this version of tuple inside our source tree.
+Starting with r173, gmock began distributing a pared down version of tr1 tuple
+that can be used on compilers without TR1.  This means that we will no longer
+need TR1 or boost on windows.
 
-chromium.patch modifies gmock/include/gmock/internal/gmock-port.h so that
-for _MSC_VER < 1500 (anything newer than Visual Studio 2008), boost tuple
-is loaded from boost/tr1/tr1/tuple.
+Recreating this package is now just exporting the wanted revision.
+Example:
 
-To recreate this install, do the following:
+    svn export --ignore-externals \
+        http://googlemock.googlecode.com/svn/trunk/ gmock
 
- *1) Checkout a copy from svn trunk using --ignore-externals to avoid
-     getting an extra copy of gtest.  Use the following command:
-       svn export --ignore-externals \
-           http://googlemock.googlecode.com/svn/trunk/ gmock
-  2) Patch it with chromium.patch.
+When checking out a copy from svn, --ignore-externals should be used to avoid
+getting an extra copy of gtest.
 
-* Pass -r [revision number] to svn export if you want a specific revision.
-The current revision of the source is listed at the top of the README.

--- ALTERNATIVES TO PATCHING --
-
-The patching of gmock to use boost in VS2005 was settled upon as the lowest
-impact solution for getting gmock working in VS2005.  Patching gmock trades
-making some assumptions regarding the internal implementations of gmock
-and boost for a simple, easy to underatnd, implementation that provides
-relatively good insulation for the rest of the build from the boost dependency.
-
-Alternate soltuions are:
-  1) Drop support for VS2005 -- too heavy-handed.
-  2) Add a "tuple" file parallel to gmock-port.h  -- still makes assumptions
-     about boost's structure.
-  3) Add boost/tr1/tr1 into the include path -- dirties the include path for
-     all dependencies.
+This command will grab the head of trunk. Optionally, -r [revision number] to
+can be passed to svn export if you want a specific revision.  The current
+revision of the source is listed at the top of the README.
