50e99fd07a Rework dependency-tracking to be poison-free 
Now new dependency edges that introduce cycles are simply rejected, not
affecting the overall graph. This simplifies the visible API and also
removes the need to restore the graph.

dc299f2f9a Reimplement LazyMutexId using MaybeUninit 
This shrinks the type by quite a bit and we don't lose state tracking as
the interal std::sync::Once already keeps track of that.

Also add a test for the new behaviour as this is a lot of unsafe code.

050ee27af6 Refactor MutexID to be self tracking 
This avoids the need to implement Drop on every wrapped mutex, and
removes the need for unsafe code in this crate.

5638ebffd8 Simplify lock guard tracking 
Instead of implementing the tracking everywhere, create a RAII-guard
that will track the state as it is held and dropped.
