capability_quintet_mangle() can be called with capability sets
containing unknown capabilities. Let's not crash when this is the
case but instead ignore the unknown capabilities.

This breaks the rule stated at the beginning of help_sudo_mode():

I've always been reluctant to invoke the current user's shell in another
user's context, hence was fully grounded in `sudo -i`. With this bit in
place `run0` will finally be feature-complete on my side ;-)
Currently, if systemd-networkd-wait-online is started with --dns, and
systemd-resolved is not running, it will exit with an error right away.
Similarly, if systemd-resolved is restarted while waiting for DNS
configuration, systemd-networkd-wait-online will not attempt to
re-connect, and will potentially never see subsequent DNS
configurations.
Improve this by adding socket units for the systemd-resolved varlink
servers, and re-establish the connection in systemd-networkd-wait-online
when we receive `SD_VARLINK_ERROR_DISCONNECTED`.
Otherwise passing invalid data means asserts get hit instead of
handling it gracefully. Other verbs already do the same checks.

Specifically, add a test case that ensures systemd-networkd-wait-online --dns
is robust against (a) systemd-resolved absence, and (b) systemd-resolved
restarts.
In case of failures we don't want to leave an image with intermediate
test configuration, as images are reused across multiple tests

Previously, all queued events were discarded on exit, hence several
events might not be processed by udevd when it is restarted. Such
situation especially easily happens on switching root.
This makes queued events serialized on exit, and deserialized in the
next invocation. Hence, no events should be lost during restarting
udevd.
This is important with the several aspects. Basically
systemd-udev-trigger.service (re)triggers all devices anyway after
switching root, But the service may be disabled or modified by admin.
Moreover, the service produces only 'add' events, and thus the service
cannot cover events with other actions generated by the kernel during
switching root. Also, the userspace triggered events may not contain
some parameters compared with events triggered by the kernel.
ssh-generator and ssh-proxy are great features, it is very handy to be
able to do:
ssh vsock/1
But, because of the '/' used as a separator, scp and rsync don't
interpret 'vsock/<CID>' as a hostname, e.g.
$ scp /etc/machine-id vsock/2222:.
cp: cannot create regular file 'vsock/2222:.': No such file or directory
$ rsync /etc/machine-id vsock/2222:.
rsync: [Receiver] change_dir#3 "(...)/vsock" failed: No such file or directory (2)
rsync error: errors selecting input/output files, dirs (code 3) at main.c(829) [Receiver=3.4.1]
An alternative is to use ',' as separator, e.g.
$ scp /etc/machine-id vsock,2222:.
This is what is being suggested here. The names with '/' are kept not to
break anything here.
Others are possible: '%', '=', '#', '@', ':', etc. As mentioned in
commit 0abd510f7f ("ssh-proxy: add ssh ProxyCommand tool that can
connect to AF_UNIX + AF_VSOCK sockets"), it is better to avoid ':' as it
is already taken by SSH itself when doing sftp, and "@" is already taken
for separating the user name. '#' will cause some issues with some
shells like ZSH when quotes are not used.
Otherwise, if already 'remove' uevent for the device is queued, then
the device node may not exist any more when 'udevadm wait' command succeeds.
