[PATCH v6 0/7] make test output coloring more intuitive

This series of commits attempts to make test output coloring more intuitive, so that:

  - red is only used for things which have gone unexpectedly wrong:
    test failures, unexpected test passes, and failures with the
    framework,

  - yellow is only used for known breakages,

  - green is only used for things which have gone to plan and
    require no further work to be done,

  - blue is only used for skipped tests, and

  - cyan is used for other informational messages.

Since unexpected test passes are no longer treated as passes, the summary lines displayed at the end of a test run have enough different possible outputs to warrant them being covered in the test framework's self-tests. Therefore this series also refactors and extends the self-tests.

Adam Spiers (7):
  tests: test number comes first in 'not ok $count - $message'
  tests: paint known breakages in bold yellow
  tests: paint skipped tests in bold blue
  tests: change info messages from yellow/brown to bold cyan
  tests: refactor mechanics of testing in a sub test-lib
  tests: test the test framework more thoroughly
  tests: paint unexpectedly fixed known breakages in bold red
