Merge branch 'ps/meson-tap-parse'

Meson-based build/test framework now understands TAP output
generated by our tests.

* ps/meson-tap-parse:
  meson: parse TAP output generated by our tests
  meson: introduce kwargs variable for tests
  test-lib: fail on unexpectedly passing tests
  t7815: fix unexpectedly passing test on macOS
  t/test-lib: fix TAP format for BASH_XTRACEFD warning
  t/test-lib: don't print shell traces to stdout
  t983*: use prereq to check for Python-specific git-p4(1) support
  t9822: use prereq to check for ISO-8859-1 support
  t: silence output from `test_create_repo()`
  t: stop announcing prereqs
