      solver: generate proper error messages · a5146f1b
      Timo Teräs authored
       * the solver no longer does look-ahead locking of names
         (could be possibly optimized later); instead names are now
         always ordered strictly to properly detect the package names
         which are unsolveable
       * basic error tests added, so we can see the most likely problem
         in dependencies easily

      solver: new package selection logic (which is not yet used) · 79b53d4d
      Timo Teräs authored
       * basic code for a backtracking, forward checking dependency satisfier
       * works better when there are tricky dependencies to solve
         (when can't just upgrade everything to most preferred versions)
       * the new code always evaluates all of 'world' constraints
         (old code just does incremental updates based on heuristics)
       * is probably somewhat slower than old code (probably unnoticeable
         difference in most cases)
       * makes easier to write support for provides and repository pinning
       * test applet and a bunch of test cases added which uses the new code
       * from the old feature set install_if is not yet implemented
