b2cce88620 optimizations (~25%) and cleanup 
Optimizations:
1. When a transistor is turned on, only add one of the nodes it
   controls to listout, otherwise group calculation would be done twice
   for this group. This simplifies recalcNodeList(). (This required
   the following change: Instead of adding the nodes that control
   transistors that have changed to listout, put the nodes that are
   switched by transistors on listout.)
2. The group value is calculated while collecting nodes, and the enum
   group_contains_value makes sure we don't check for weaker value
   indicators than have already been established.
3. listout is now a set, no node will be visited twice for group
   calculation, within one interation.
4. When setting input pins of the package to a value, only recalc the
   node if it actually changes.
5. Toggling a transistor is done by assigning it the group value
   instead of the inverse of its value.

Cleanup:
* Merge the concept of listin with the concept of nodes that change
  from the outside and trigger a recalc.
