'progress.c' has seen a few fixes recently [1], and, unfortunately,
some of those fixes required further fixes [2]. It seems it's time to
have a few tests focusing on the subtleties of the progress display.
Add the 'test-tool progress' subcommand to help testing the progress
display, reading instructions from standard input and turning them
into calls to the display_progress() and display_throughput()
functions with the given parameters.
The progress display is, however, critically dependent on timing,
because it's only updated once every second or, if the toal is known
in advance, every 1%, and there is the throughput rate as well. These
make the progress display far too undeterministic for testing as-is.
To address this, add a few testing-specific variables and functions to
'progress.c', allowing the the new test helper to:
- Disable the triggered-every-second SIGALRM and set the
'progress_update' flag explicitly based in the input instructions.
This way the progress line will be updated deterministically when
the test wants it to be updated.
- Specify the time elapsed since start_progress() to make the
throughput rate calculations deterministic.
Add the new test script 't0500-progress-display.sh' to check a few
simple cases with and without throughput, and that a shorter progress
line properly covers up the previously displayed line in different
situations.

lines, 2019-04-12) and 9f1fd84e15 (progress: clear previous
progress update dynamically, 2019-04-12).
