Add optional pause() notification feature to the test suite
Originally created by @anonym on #12175 (Redmine)
I want something that can run an arbitrary shell (set via the
configuration system) command when pause()
is called, e.g. on failure
when --interactive-debugging
is used. This will be pretty useful when
multitasking with long test suite runs, so you immediately are notified
when a test fails (or when you reached a temporary pause()
breakpoint).
