third_party/protobuf: update to upstream r412.

third_party/protobuf: update to upstream r412.

1) Got an upstream diff 411:412 from svn
2) Applied
3) Modified protobuf.gyp to make it platform independent thanks to the new
   guards added in atomicops_internals_x86_gcc.cc and
   atomicops_internals_x86_msvc.cc.
   Note that the previous change adding atomicops added a significant
   complexity to protobuf.gyp to handle platform-specific source files. Because
   it was using target_arch only, it did not even work properly. Indeed
   protobuf_lite needs to deal with the host architecture when it is built to
   be used by protoc.

LGTM.

n.b. you codereview tools seem to be out of date as the email contained a link
to the old, insecure codereview.chromium.org site.
