Pacman side code consolidation- unify callback functions to one file 

Some more major code reorginization here. The download progress callback
function has been renamed and moved to callback.c, which is the former
trans.c with the download and log callbacks added. In addition, this allows
util.c to be cleaned up as fill_progress can now be static in callback.c.
We've also cut two more source files out.
