74900a6b35 progress API: unify stop_progress{,_msg}(), fix trace2 bug
Fix a bug that's been with us ever since 98a1364740 (trace2: log
progress time and throughput, 2020-05-12), when the
stop_progress_msg() API was used we didn't log a "region_leave" for
the "region_enter" we start in "start_progress_delay()".

The only user of the "stop_progress_msg()" function is
"index-pack". Let's add a previously failing test to check that we
have the same number of "region_enter" and "region_leave" events, with
"-v" we'll log progress even in the test environment.

In addition to that we've had a submarine bug here introduced with
9d81ecb52b (progress: add sparse mode to force 100% complete message,
2019-03-21). The "start_sparse_progress()" API would only do the right
thing if the progress was ended with "stop_progress()", not
"stop_progress_msg()".

The only user of that API uses "stop_progress()", but let's still fix
that along with the trace2 issue by making "stop_progress()" a trivial
wrapper for "stop_progress_msg()".

We can also drop the "if (progress)" test from
"finish_if_sparse()". It's now a helper for the small
"stop_progress_msg()" function. We'll already have returned from it if
"progress" is "NULL".

a02014bb4c progress.h: format and be consistent with progress.c naming
Fix an inconsistency introduced in dc6a0757c4 (make struct progress
an opaque type, 2007-10-30) and rename the "progress" parameters to
stop_progress{,_msg}() to "p_progress". Now these match the
corresponding parameters in the *.c code.

While we're at it let's move the definition of the former below the
latter, a subsequent change will start defining stop_progress() in
terms of stop_progress_msg(). Let's also remove the excess whitespace
at the end of the file.

Updating the display with progress message has been cleaned up to
deal better with overlong messages.

* sg/overlong-progress-fix:
  progress: break too long progress bar lines
  progress: clear previous progress update dynamically
  progress: assemble percentage and counters in a strbuf before printing
  progress: make display_progress() return void

9219d12777 progress: make display_progress() return void
Ever since the progress infrastructure was introduced in 96a02f8f6d
(common progress display support, 2007-04-18), display_progress() has
returned an int, telling callers whether it updated the progress bar
or not.  However, this is:

  - useless, because over the last dozen years there has never been a
    single caller that cared about that return value.

  - not quite true, because it doesn't print a progress bar when
    running in the background, yet it returns 1; see 85cb8906f0
    (progress: no progress in background, 2015-04-13).

The related display_throughput() function returned void already upon
its introduction in cf84d51c43 (add throughput to progress display,
2007-10-30).

Let's make display_progress() return void, too.  While doing so
several return statements in display() become unnecessary, remove
them.

9d81ecb52b progress: add sparse mode to force 100% complete message
Add new start_sparse_progress() and start_delayed_sparse_progress()
constructors and "sparse" flag to struct progress.

Teach stop_progress() to force a 100% complete progress message before
printing the final "done" message when "sparse" is set.

Calling display_progress() for every item in a large set can
be expensive.  If callers try to filter this for performance
reasons, such as emitting every k-th item, progress would
not reach 100% unless they made a final call to display_progress()
with the item count before calling stop_progress().

Now this is automatic when "sparse" is set.

d6861d0258 progress: fix progress meters when dealing with lots of work
The possibility of setting merge.renameLimit beyond 2^16 raises the
possibility that the values passed to progress can exceed 2^32.
Use uint64_t, because it "ought to be enough for anybody".  :-)

8aade107dd progress: simplify "delayed" progress API
We used to expose the full power of the delayed progress API to the
callers, so that they can specify, not just the message to show and
expected total amount of work that is used to compute the percentage
of work performed so far, the percent-threshold parameter P and the
delay-seconds parameter N.  The progress meter starts to show at N
seconds into the operation only if we have not yet completed P per-cent
of the total work.

Most callers used either (0%, 2s) or (50%, 1s) as (P, N), but there
are oddballs that chose more random-looking values like 95%.

For a smoother workload, (50%, 1s) would allow us to start showing
the progress meter earlier than (0%, 2s), while keeping the chance
of not showing progress meter for long running operation the same as
the latter.  For a task that would take 2s or more to complete, it
is likely that less than half of it would complete within the first
second, if the workload is smooth.  But for a spiky workload whose
earlier part is easier, such a setting is likely to fail to show the
progress meter entirely and (0%, 2s) is more appropriate.

But that is merely a theory.  Realistically, it is of dubious value
to ask each codepath to carefully consider smoothness of their
workload and specify their own setting by passing two extra
parameters.  Let's simplify the API by dropping both parameters and
have everybody use (0%, 2s).

Oh, by the way, the percent-threshold parameter and the structure
member were consistently misspelled, which also is now fixed ;-)

a984a06a07 nicer display of thin pack completion
In the same spirit of prettifying Git's output display for mere mortals,
here's a simple extension to the progress API allowing for a final
message to be provided when terminating a progress line, and use it for
the display of the number of objects needed to complete a thin pack,
saving yet one more line of screen display.

218558af59 make display of total transferred more accurate
The throughput display needs a delay period before accounting and
displaying anything.  Yet it might be called after some amount of data
has already been transferred.  The display of total data is therefore
accounted late and therefore smaller than the reality.

Let's call display_throughput() with an absolute amount of transferred
data instead of a relative number, and let the throughput code find the
relative amount of data by itself as needed.  This way the displayed
total is always exact.

96a02f8f6d 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.
