This avoids GIL limitations with using threads for parallel processing.
This reworks the fetch logic to return results for processing in the
main thread instead of leaving every thread to do its own processing.
We have to tweak the chunking logic a little here because multiprocessing
favors batching over returning immediate results when using a larger value
for chunksize. When a single job can be quite slow, this tradeoff is not
good UX.

We're already keeping tracking of the start time, so might as
well use it to display overall execution time for steps.

The idea for skipping some progress updates was to avoid spending
too much time on the progress bar itself. Unfortunately, for large
projects (100s if not 1000s) of repos, we get into the situation
with large/slow checkouts that we skip showing updates when a repo
finishes, but not enough repos finished to increase the percent.
Since the progress bar should be relatively fast compared to the
actual network & local dick operations, have it show an update
whenever the caller requests it. A test with ~1000 repos shows
that the progress bar in total adds <100ms.

The current sync output displays "Fetching project" and "Checking out
project" messages and progress bar updates independently leading to a
lot of spam. Lets merge these periodic outputs with the status bar to
get a little bit tighter output in the normal case. This doesn't solve
all our problems, but gets us closer.

When displaying progress bars, we use \r to reset the cursor to the
start of the line before showing the new update. This assumes the
new line will fully erase whatever was displayed there previously.
The "done" codepath tries to handle this by including a few extra
spaces at the end of the message to "white out" what was there.
Lets replace that hack with the standard ECMA escape sequence that
clears the current line completely. This is the CSI "erase in line"
sequence that the terminal will use to delete all content. The \r
is still needed to move the cursor to the start of the line. Using
this sequence should be OK since we're already assuming the terminal
is ECMA compliant with our use of coloring sequences. We also put
the \r after the CSI sequence on the off chance the terminal can't
process it and displays a few bytes of garbage.
The other improvement is to the syncbuffer API. When it dumps its
status information, it almost always comes after a progress bar
update which leads to confusing comingled output. Something like:
Fetching projects: 100% (2/2) error: src/platform2/: branch ...
Since the progress bar is "throw away", have the syncbuffer reset
the current output to the start of the line before showing whatever
messages it has queued.

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.
