autopkgtest

We see BlockingIOError quite a bit these days on Ubuntu's autopkgtest
cloud when trying to write to sys.stderr. Not sure why it's non-blocking,
seems Python sets it up that way sometimes...

nova: Drop nova network-show, we're all openstack now

ssh-setup/nova: Use `openstack network show` in preference to `nova`

Once we don't care about xenial's `openstack` client tools then we can
drop the fallback and upstream this.

UBUNTU: setup-testbed: Setup Acquire::Retries 10, like debci does

da7d955... by Julian Andres Klode on 2021-04-07

setup-testbed: Also remove needrestart

needrestart installs a dpkg hook that fails and inserts errors,
causing the apt test suite to fail (there's no way to isolate against
system dpkg hooks so far), and is installed in cloud images atm.

ssh-setup/nova: Quote arguments to `tr`

Otherwise they can be expanded as globs, which breaks badly if they
match anything in the cwd.

lxd: Add a hook_prepare_reboot and pass arguments from it to wait_reboot

We've got a race condition currently. When rebooting the testbed, the
flow is like this:

  hook_prepare_reboot
  reboot
  hook_wait_reboot

The idea is that hook_wait_reboot waits for the testbed to come back up,
so we can go on with the tests. For lxd, this means fetch the uptime,
and wait for it to go backwards, indicating the the reboot happened.

We fetch the 'initial' uptime in hook_wait_reboot, though. As this is
after we actually ask the testbed to reboot itself, there's a race
condition. If we managed to go down before we get into hook_wait_reboot,
we will not be able to get the initial uptime.

Instead, add a prepare_reboot hook to autopkgtest-virt-lxd, which
fetches the initial uptime. Then it needs to be able to return a value
back to the caller, so that wait_reboot can know what it needs to
compare to. That needs a bit of adjustment to hook_wait_reboot's
interface, to allow it to accept arguments. We make this generic, so
it's optional across backends.

TEMPORARY: RT#127293: install haveged again

rng-tools is not working everywhere, so continue to install haveged
in the meantime.

Include cross-arch packages in pinning.

To ensure cross-installability of 'unstable' versions of libraries whose
native versions are also installed in the base system, and to ensure the
'unstable' versions of cross packages are used, our binary package pins must
include both native and cross packages. Some of the values included in the
pin will be nonsense (the cross variant of any Arch: all package), but this
doesn't matter.

Handle cross-arch test deps for packages which are not Arch: any.

If the package is only built on a subset of archs, the [arch] list is
part of the string in my_packages and needs to be accounted for. Don't
worry about the possibility that our target arch isn't actually in the
architecture list, since in that case it shouldn't be a test dep anyway.
