Change the usage of the "test-tool progress" introduced in
2bb74b53a4 (Test the progress display, 2019-09-16) to take command
like "start" and "stop" on stdin, instead of running them implicitly.
This makes for tests that are easier to read, since the recipe will
mirror the API usage, and allows for easily testing invalid usage that
would yield (or should yield) a BUG(), e.g. providing two "start"
calls in a row. A subsequent commit will add such tests.

/*

|
* A test helper to exercise the progress display.
|
|
*
|
|
* Reads instructions from standard input, one instruction per line:
|
|
*
|
|
* "start <total>[ <title>]" - Call start_progress(title, total),
|
|
* Uses the default title of "Working hard"
|
|
* if the " <title>" is omitted.
|
|
* "progress <items>" - Call display_progress() with the given item count
|
|
* as parameter.
|
|
* "throughput <bytes> <millis> - Call display_throughput() with the given
|
|
* byte count as parameter. The 'millis'
|
|
* specify the time elapsed since the
|
|
* start_progress() call.
|
|
* "update" - Set the 'progress_update' flag.
|
|
* "stop" - Call stop_progress().
|
|
*
|
|
* See 't0500-progress-display.sh' for examples.
