tests: teach the test-tool to generate NUL bytes and use it
In cc95bc2025 (t5562: replace /dev/zero with a pipe from
generate_zero_bytes, 2019-02-09), we replaced usage of /dev/zero (which
is not available on NonStop, apparently) by a Perl script snippet to
generate NUL bytes.
Sadly, it does not seem to work on NonStop, as t5562 reportedly hangs.
Worse, this also hangs in the Ubuntu 16.04 agents of the CI builds on
Azure Pipelines: for some reason, the Perl script snippet that is run
via `generate_zero_bytes` in t5562's 'CONTENT_LENGTH overflow ssite_t'
test case tries to write out an infinite amount of NUL bytes unless a
broken pipe is encountered, that snippet never encounters the broken
pipe, and keeps going until the build times out.
Oddly enough, this does not reproduce on the Windows and macOS agents,
nor in a local Ubuntu 18.04.
This developer tried for a day to figure out the exact circumstances
under which this hang happens, to no avail, the details remain a
mystery.
In the end, though, what counts is that this here change incidentally
fixes that hang (maybe also on NonStop?). Even more positively, it gets
rid of yet another unnecessary Perl invocation.

Test the progress display
'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.
[1] See commits 545dc345eb (progress: break too long progress bar
lines, 2019-04-12) and 9f1fd84e15 (progress: clear previous
progress update dynamically, 2019-04-12).

line, 2019-05-19)
