From d317acaee8e9c20056a84ee0fc0089cc6610a412 Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>

Subject: Add a series of pm_printf functions to pacman frontend

Add pm_printf, pm_fprintf, and pm_vfprintf to the pacman frontend for use by
debug printing and other output messages from pacman. These will be
incorporated into the log callback functions in the next iteration of
changes.
