The signal_hook crate makes this easy, but unfortunately insists on
hardcoding SA_RESTART. So we have to then use libc directly to patch
that out...
Still worth using signal_hook for the atomic flag helper though.

On any panic, we dump out the last ~30 seconds of IVSENSE data along
with the starting state and panic reason.
Also add a feature to panic if the gain reduces too much. This can be
used to try to catch badness.

the bindings we rely on were merged in v0.7.1, so we
no longer need to carry the crate downstream.
