v1->v2: Redid all the ovs-atomic changes to fix a bug in the GCC 4.x (x <
7) support. This was not a simple fix; all the ovs-atomic patches are
essentially new. Also, changed the ovs-rcu library to use "consume" rather
than "acquire" based on this:

Ben Pfaff (15):
ovs-atomic-gcc4+: Fix parenthesization in atomic_read_explicit().
compiler: New macro for defining aligned structs.
util: New macro PAD_SIZE.
util: Move CACHE_LINE_SIZE here.
ovs-atomic: Factor type declarations out of most implementations.
ovs-atomic: Use raw types, not structs, when locks are required.
ovs-atomic-pthreads: Use global shared locks for atomic_flag also.
ovs-atomic-types: Move into ovs-atomic.h.
ovs-atomic: Delete atomic, atomic_flag, ovs_refcount destroy
functions.
ovs-rcu: New library.
ofproto: Use RCU to protect rule_actions.
util: New functions for allocating memory while avoiding false
sharing.
ovs-thread: Replace ovsthread_counter by more general
ovsthread_stats.
dpif-netdev: Use ovsthread_stats for flow stats.
dpif-netdev: Use RCU to protect data.
