solver: rewrite backtracking and scoring system
* properly do absolute scoring now, the previous scoring where
preference could get reduced could have caused incorrect early
pruning of search tree
* backtracking is now separated from package state, and first
branching point is the decision if a name is left unassigned
or if something _has_ to be assigned. this allows multiple future
search tree optimizations like handling of common dependencies
early.
* merge common dependency names early to provide deeper forward
checking.
