The point of the progress meter is to let the user know that the
task is progressing, and give them a chance to estimate when it will
be complete. If the task completes in under 0.5 seconds then it
is sufficiently fast enough that the user doesn't need to be kept
up-to-date on its progress; in fact showing the meter may just slow
the task down waiting on the tty to redraw.
We now delay the progress meter 0.5 seconds (or 1 second if the
Python time.time() function isn't accurate enough) to avoid any
really fast tasks, like a no-op local sync.

The trace output often interfers with the progress meter, so its
easier to just disable the progress meter if trace is active.
Its already verbose enough to let the user know we are working,
which is all the progress meter is there for anyway.

If there are no projects to fetch, the progress meter would
have divided by zero during `repo sync`, and that throws a
ZeroDivisionError. Instead we report the progress with an
unknown amount remaining.

This way users can see how much is left during fetch. Its
especially useful when most syncs are no-ops but there are
hundreds of repositories to poll.
