Merge lp:~laney/britney/autopkgtest-no-delay-if-never-passed into lp:britney

[Iain Lane]

This is an attempt at fixing bug #1501699.

With this branch, we now take into account the "ever_passed" flag to decide if a test run has passed or not. It has passed if the test is ALWAYSFAILED or RUNNING but has never passed, for all arches.

Many testcases relied on the previous behaviour, so I inserted some 'passing' test results to cause the packages to be held.

There are some delicacies around kernel triggering that I don't fully understand (this is my first venture into britney/autopkgtest) - please check I didn't break anything.

Add passing results for various tests

We're going to modify britney so that RUNNING tests don't block
promotion if they have never failed - for this we will need to change a
few tests so that the packages being tested have passed before, meaning
that there could potentially be a regression.

tests: pretty print the excuses so that they are readable

Fix typo in test name triggerered -> triggered

Don't wait for tests which have never passed

They won't ever block promotion, so we might as well make them
candidates right away (but trigger their tests).

Restrict ADT_ARCHES to architectures we actually run for

This makes it simpler to run britney against a PPA with
--architectures='i386 amd64'.

Split self.options.adt_arches once during initialization

For consistency with all other self.options.*_arches.

tests: Use proper triggers in all tests

Also introduce a tr() shortcut for those. Drop the now redundant
test_rerun_failure_triggers().

Autopkgtest: Request one test run per trigger for all packages

Stop special-casing the kernel and move to one test run per trigger. This
allows us to only install the triggering package from unstable and run the rest
out of testing, which gives much better isolation.
