uBPF should support support the new atomic instructions

eBPF ABI was extended to add support for atomic operations:

This is important as it allow eBPF programs to update maps in a lock-free manner.

I think we should probably resolve #45 (maybe by reviving #53 as an optional feature?) before addressing atomics, since we don't have any tests for using maps right now.
