[WIP] implement a lock-free MPMC ring buffer
TODO: actually use the right memory barriers in the right places
TODO: eliminate false sharing between mpmc_ptr_ring members
TODO: reconsider atomic_long_t vs. atomic_t, vs. the type of size in _init()
TODO: sprinkle likely/unlikely on some branches
FIXME: it still crashes
