Flesh out the package kit solver API quite a bit more

* Reorganize things a bit: - BSolver is now an abstract base class. - A libsolv based implementation, LibsolvSolver, lives in a new add-on, which is loaded lazily. - Get rid of libpackage_solver. Save for LibsolvSolver everything is moved to libpackage. - This is a nicer solution for the cyclic dependency caused by libsolv (libsolvext to be precise) using the package kit for reading repositories and package files. * Add a solver result data structure and and an accessor the solver. * Add problem reporting support to the solver. There aren't data structures for the problem solutions yet and support for selecting solutions and re-solving is missing as well.
