bundle1: fix bundle1-denied reporting for pull over ssh Changeset b288fb2724bf introduced a config option to have the server deny pull using bundle1. The original protocol has not really been design to allow that kind of error reporting so some hack was used. It turned the hack only works on HTTP and that ssh server hangs forever when this is used. After further digging, there is no way to report the error in a unified way. Using `ooberror` freeze ssh and raising 'Abort' makes HTTP return a HTTP-500 without further details. So with sadness we implement a version that dispatch according to the protocol used. Now the error is properly reported, but we still have ungraceful abort after that. The protocol do not allow anything better to happen using bundle1.

bundle-tests: operate from outside a repository We are about to add a test for ssh pull/cloning being denied because of bundle1 usage. For this, it is cleaner to not operate from the clone using http. So we update the test beforehand for clarity. This is more churns that what I'm happy to see on stable, but the rests of the series is worth it in my opinion.

bundle1: display server abort hint during unbundle The code was printing the abort message but not the hint. This is now fixed.

bundle1: fix bundle1-denied reporting for push over ssh Changeset b288fb2724bf introduced a config option to have the server deny push using bundle1. The original protocol has not really be design to allow such kind of error reporting so some hack was used. It turned the hack only works on HTTP and that ssh wire peer hangs forever when the same hack is used. After further digging, there is no way to report the error in a unified way. Using 'ooberror' freeze ssh and raising 'Abort' makes HTTP return a HTTP500 without further details. So with sadness we implement a version that dispatch according to the protocol used. We also add a test for pushing over ssh to make sure we won't regress in the future. That test show that the hint is missing, this is another bug fixed in the next changeset.
