I'm probably to blame for that - I've removed the s_lock.h (it wasn't
spin.h for some reason) include from lwlock.h:

Clean up includes of s_lock.h.
Users of spinlocks should use spin.h, not s_lock.h. And lwlock.h
hasn't utilized spinlocks for quite a while.

I think including spin.h is the right fix, given that it needs to know
the size of s_lock.
