The kernel will not allow you to modify existing mount flags on a volume
when bind mounting it to another place. Since /sys/fs/cgroup/systemd is
mounted noexec on the host, it needs to be mounted with the same flags
in the rootless container.

Do not wait for events to occur before writing the OK header.
Events can take an unknown amount of time to occur and clients
do not need to wait until then to know if the connection is
good.

Record the user-specified "raw" image name in the SpecGenerator, so we
can pass it along to the config when creating a container. We need a
separate field as the image name in the generator may be set to the
ID of the previously pulled image - ultimately the cause of #7404.
Reverting the image name from the ID to the user input would not work
since "alpine" for pulling iterates over the search registries in the
registries.conf but looking up "alpine" normalizes to
"localhost/alpine".
Recording the raw-image name directly in the generator was the best of
the options I considered as no hidden magic from search registries or
normalizations (that may or may not change in the future) can interfere.
The auto-update backend enforces that the raw-image name is a
fully-qualified reference, so we need to worry about that in the front
end.

Move the `rootless-cni-infra` image to `quay.io/libpod/rootless-cni-image:$tag`
where $tag has the format `$version-$architecture`. Whenever we upload
a new image (e.g., after changing the Containerfile), we need to make
sure to increase the version number (an ordinary integer for simplicity) so we
have a notion of support.
Thanks to @AkihiroSuda for working on rootless CNI!

Add new system check confirming that "podman foo -l arg"
throws an error; and fix lots of instances where code
was not doing this check.
I'll probably need to add something similar for --all but
that can wait.

* Refactor/Rename channel.WriteCloser() to encapsulate the channel
* Refactor build endpoint to "live" stream buildah output channels
over API rather then buffering output
* Refactor bindings/tunnel build because endpoint changes
* building tar file now in bindings rather then depending on
caller
* Cleanup initiating extra image engine
* Remove setting fields to zero values (less noise in code)
* Update tests to support remote builds

A reading of LabelVolumePath suggests that the intended behavior
upon encountering ENOTSUP is to log the issue and continue without
error, while all other errors in the Relabeling operation should
be considered errors of LabelVolumePath and passed up accordingly.
This is not the behavior that is encountered, as this test shows:
it is instead considered an error if and only if the Relabeling
operation returns ENOTSUP, spitting out a somewhat incongruous
error message, while all other error types that may be returned
are logged without being propogated, with an even more incongruous
error message saying that the operation was not supported.
The comparison was changed to match the behavior documented by the
log messages, and a test was added that will simulate executing
this function on a path where the mounted filesystem does not
support SELinux labels, with the assertion that the function should
not return an error in order to highlight the condition these
changes seek to alleviate.

Fix the image-size calculations of system-df, where the shared size is
the actual shared size with other images (including children) and the
(total) size is the sum of the shared and unique size [1].
To calculate parent/child relations, make use of the recently added
layer tree which allows for quick (and cached!) calculations.
Break calculating image disk usages into the image runtime to a) access
the layer tree, and b) make the code easier to maintain and extend.

As error types are not preserved on the client side (due to marshaling),
we cannot use `errors.Cause(...)` and friends but, unfortunately, have
to fall back to looking for substring the error messages.
Change the error checks in remote run to do substring matches and fix
issue #7340.
