commit 6b01e58ff708c17f74b560fe1b57f7733b78da53
Author: staraz <staraz@chromium.org>
Date: Thu Nov 10 18:19:11 2016

Replaced cc::SurfaceId::nonce_ with base::UnguessableToken

base::SurfaceId::nonce_ is an uint64 generated at random to make the entire
surface id unguessable.
base::UnguessableToken is a wrapper for 2 uint64 (high_ and low_).
high_ and low_ are generated at random using base::UnguessableToken::Create().
base::UnguessableToken achieves the same goal as the original
cc::SurfaceId::nonce_ with better security and uses more common code.

commit d75809ef13714bcc4e960779d2178d9f99783147
Author: dpranke <dpranke@chromium.org>
Date: Thu Nov 10 20:04:44 2016

Revert of Replaced cc::SurfaceId::nonce_ with base::UnguessableToken (patchset #25 id:480001 of https://codereview.chromium.org/2379653006/ )

Reason for revert:
Looks like this added a static initializer to surface_manager.cc via the change to unguessable_token
