test: use bundle2 in test-ssh Now that we have a bundle1 version of this test, we can move the main version to bundle2. This lets us handle the ouput change from using the bundle2 protocol earlier.

test: copy test-ssh.t to test-ssh-bundle1.t We want to keep both code paths tested. The test is a bit too extensive to simply introduce dual testing in it so we make a copy for each protocol version.

test: lock test-unbundlehash to bundle1 usage It is testing a bundle1 specific behavior. Bundle2 has its own way there. See inline comment for details.

test: use bundle2 in test-acl This test makes extensive use of --debug so moving to bundle2 based exchange has a massive impact. We do it early to reduce the noise create by a future usage of bundle2 as the default protocol.
