Make the rule tree actually threadsafe
...
RuleTree::gc is now a safe method that any thread can call
at any time, and StrongRuleNode values can all be dropped
whenever their owner want to, on any thread.

Always upgrade existing weak child references in the rule tree
...
Just because we didn't find a child when read-locking a node children list
doesn't mean it still won't exist while we wait to upgrade the read lock
into a write lock to create the child.

Introduce a new type UnsafeBox<T> in the rule tree
...
This lets us rely less on raw pointers, thus better tracking the lifetime
of the rule node values while dropping strong references etc.

Remove WeakRuleNode::clone
...
MallocSizeOf for RuleTree should not keep around weak references in
case someone runs a GC meanwhile.
