TST,BUG: Explicitly allow running tests multiple times

[HaoZeke]

These are extracted from the meson port effort [1] but are not directly tied to a build system. The main fixes involve:

• Calling abort over stop
  • Equally well supported (in terms of language standards / compilation), but stop reports no errors (i.e. return code was always 0), and doesn't include a backtrace.
• Changing the test write status from new to replace
  • Allows tests to run multiple times without a clean step in between

M1 failure seems unrelated..
