Remove knowledge from the library to install packages.
The library is only responsible now to find all binary packages from repositories, sort them and create a dictionary with all details. The frontend (xbps-bin) provides support for this, and this allows for more flexibility and removes some stuff that didn't belong in the library. While here implemented support to show total download/installed size for all packages that are going to be installed. Next step will be to implement user interactivity before installing/removing/updating packages. --HG-- extra : convert_revision : 858e9a89bc6a60b348435f2416a8af3ebb6ea5c9
