Implemented a crappy version of -Qu (query upgrades). This simply outputs the

packages to be upgraded in a -Su operation.  Much of the code is duplicated from
sync.c.
TODO: move the implementation to upgrades.c, and reimplement the sync_sysupgrade
function in terms of this:
    trans->packages = alpm_get_upgrades();
