state: rework changeset calculation algorithm
Calculate changesets directly by stabilizating the package graph instead of recalculating the whole graph and then diffing (similar approach as seen in 'smart' package manager). The algorithm is not complete: defferred search space forking is missing. So you don't always get a solution on complex graphs. Benefits: - usually the search state tree is smaller (less memory used) - speed relational to changeset size, not database size (usually faster) - touch only packages related to users request (can work on partitially broken state; upgrades only necessary packages, fixes #7) Also implemented: - command prompt to confirm operation if packages are deleted or downgraded - requesting deletion of package suggests removal of all packages depending on the package being removed (you'll get list of packages that also get removed if you want package X removed) - option --simulate to see what would have been done (mainly for testing) - an untested implementation of versioned dependencies and conflicts A lot has changed, so expect new bugs too.
