Reimplement TotalDownload functionality
Add a new totaldlcb callback function to libalpm and make pacman utilize it when the TotalDownload option is enabled. This callback function is pretty simple- it is meant to be called once at the beginning of a "list download" action, and once at the end (with value 0 to indicate the list has been finished). The frontend is responsible for keeping track of adding individual file download amounts to the total xfered amount in order to display some sort of overall progress.
