Remove frontend add code that is no longer necessary
Change the pacman_upgrade stub function to do what pacman_add used to do so we can eliminate pacman_add. Move the code to the more-descriptive name of upgrade.c. Note that we have made no changes to the backend libalpm, where an ADD type transaction could still be supported. Signed-off-by: Dan McGee <dan@archlinux.org>
