This is the result of some changes and cleanup I did to nicely support
progress with throughput display, and avoid those random crashes the
previous patches introduced. All tests are OK now after every patch.
This is meant to replace my latest 2 patches currently in pu.

The progress count is per fanout directory, so it is useless to call
it for every file as the count doesn't change that often.

This allows for better management of progress "object" existence,
as well as making the progress display implementation more independent
from its callers.

Since it is now OK to pass a null pointer to display_progress() and
stop_progress() resulting in a no-op, then we can simplify the code
and remove a bunch of lines by not making those calls conditional all
the time.

This adds the ability for the progress code to also display transfer
throughput when that makes sense.
The math was inspired by commit c548cf4ee0737a321ffe94f6a97c65baf87281be
from Linus.

This one triggers only when git-pack-objects is called with
--all-progress and --stdout which is the combination used by
git-push.

If you go back into the history and look at the commit message for
when I introduced this per-object display_progress() call we find
the following:
commit b5d72f0a4cd3cce945ca0d37e4fa0ebbfcdcdb52
Author: Shawn O. Pearce <spearce@spearce.org>
Date: Fri Oct 19 00:08:37 2007 -0400
[...snip...]
We perform the display_progress() call from within the very innermost
loop in case we spend more than 1 second within any single object
directory. This ensures that a progress_update event from the
timer will still trigger in a timely fashion and allow the user to
see the progress meter.
During my testing with a 40,000 loose object case (yea, I fully
unpacked a git.git clone I had laying around) my system stalled
hard in the first object directory. A *lot* longer than 1 second.
So I got no progress meter for a long time, and then a progress
meter appeared on the second directory.
The display_progress() call already does a reasonably cheap
comparsion to see if the timer has tripped or if the percent complete
has changed. So I figured it was more useful to get feedback to
the user that we were working, but were going to take a while,
than it was to optimize a few machine instructions out of that
inner-most per-object loop.
So I'm a little against this patch. But I think I understand why
you think its worth doing. I just consider the progress feedback
more important than the few machine cycles avoiding it saves.

Hmmmm OK. I overlooked that.

But then don't you get a "0% (1/256)" on the screen for a while, like if
it was stalled? Might be better than nothing at all I suppose...

OK, I don't mind reverting the patch, or actually providing another one
to move the call back inside the loop since other changes will prevent a
clean revert.
