common progress display support
Instead of having this code duplicated in multiple places, let's have a common interface for progress display. If someday someone wishes to display a cheezy progress bar instead then only one file will have to be changed. Note: I left merge-recursive.c out since it has a strange notion of progress as it apparently increase the expected total number as it goes. Someone with more intimate knowledge of what that is supposed to mean might look at converting it to the common progress interface.
