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.

- run tests: better "skip" message for docker-archive test;
remove FIXME, document that podman-remote doesn't support it
- run tests: instrument the --conmon-pidfile test in hopes
of tracking down flake #7580: cross-check pidfile against
output of 'podman inspect', and add some debug messages
that will only be seen on test failure.
- load tests: the pipe test: save and load a temporary tag,
not $IMAGE. Primary reason is because of #7371, in which
'podman load' assigns a new image ID (instead of preserving
the saved one). This messes with our image management, and
it turns out to be nonfixable.

After attaching to a container, we wait for the container to finish and
return its exit code. Waiting for the container may not always succeed,
for instance, when the container has been force removed by another
process. In such case, we have to look at the *last* container-exit
event.
Also refactor the `ContainerRun` method a bit to return early on errors
and de-spaghetti the code.
Enable the remote-disabled system test.

There is no need to setup the image and container engine when calling
a command with subcommands since we only print a usage message.
e.g `podman`,`podman container`
This also allows the remote client to show the usage message on
these commands without a running endpoint. I added a test for this.

CI and system tests currently pull some images from docker.io.
Eliminate that, by:
- building a custom image containing much of what we need
for testing; and
- copying other needed images to quay.io
(Reason: effective 2020-11-01 docker.io will limit the
number of image pulls).
The principal change is to create a new quay.io/libpod/testimage,
using the new test/system/build-testimage script, instead of
relying on quay.io/libpod/alpine_labels. We also switch to
using a hardcoded :YYYYMMDD tag, instead of :latest, in an
attempt to futureproof our CI. This image includes 'httpd'
from busybox-extras, which we use in our networking test
(previously we had to pull and run busybox from docker.io).
The testimage can and should be extended as needed for future
tests, e.g. adding test file content or other useful tools.
For the '--pull' tests which require actually pulling from
the registry, I've created an image with the same name but
tagged :00000000 so it will never be pulled by default.
Since this image is only used minimally, it's just busybox.
Unfortunately there remain two cases we cannot solve in
this tiny alpine-based image:
1) docker registry
2) systemd
For those, I've (manually) run:
podman pull [ docker.io/library/registry:2.7 | registry.fedoraproject.org/fedora:31 ]
podman tag !$ quay.io/...
podman push !$
...and amended the calling tests accordingly.
I've tried to make the the smallest reasonable diff, not the
smallest possible one. I hope it's a reasonable tradeoff.

The test that does 'adduser' in a keep-id container had a
really dumb bug: if the user running the test has UID 1000,
then podman itself (via keep-id) will add the "1000" passwd
entry, and the in-container "adduser" will allocate 1001,
making our test fail. This triggered in f31/f32 podman gating
tests, but (?!?) never in rawhide gating tests.
Solution: explicitly feed a UID to adduser. Make sure that
it's not the same as the UID of the current user.
Also (unrelated): fix a ridiculous "run mkdir || die". At
the time I wrote that I probably had no idea how BATS works.

info, images, run, networking tests: remove some skip_if_remote()s
that were added in the varlink days. All of these tests now seem
to work with APIv2.
help test: check that first output line from 'podman --help'
is the program description (regression check for #7273).
load test: clean up stray images, rewrite test to make it conform
to existing convention. In the process, discover and file #7337
exec test (and networking): file #7360, and add FIXME comment
to skip()s suggesting evaluating those tests once that is fixed.
pod test: now that #6328 is fixed, use 'podman pod inspect --format'
instead of relying on jq
Various other tests: add an explanation of why test is disabled
so we can more easily distinguish "this will never be meaningful
under remote" vs "hey, doesn't work for now, but maybe someday".

Oops. PR #6693 (sdnotify) added tests, but they were disabled
due to broken crun on f31. I tried for three weeks to get a
magic CI:IMG PR to update crun on the CI VMs ... but in that
time I forgot to actually enable those new tests.
This PR removes a 'skip', replacing it with a check that systemd
is running plus one more to make sure our runtime is crun. It
looks like sdnotify just doesn't work on Ubuntu (it hangs), and
my guess is that it's a crun/runc issue.
I also changed the test image from fedora:latest to :31, because,
sigh, fedora:latest removed the systemd-notify tool.
WARNING WARNING WARNING: the symptom of a missing systemd-notify
is that podman will hang forever, not even stopped by the timeout
command in podman_run! (Filed: #7316). This means that if the
sdnotify-in-container test ever fails, the symptom will be that
Cirrus itself will time out (2 hours?). This is horrible. I
don't know what to do about it other than push for a fix for 7316.

- new sanity checks for podman-remote:
- first, confirm that when PODMAN is "-remote",
we actually talk to a server (validated by
presence of "Server:" string in "podman version").
- second, add test for #7212, in which we run
"podman --remote" (podman with --remote flag,
not podman-remote command) and make sure --remote
is allowed both as the first option and also
with other flag options preceding.
- new test for "podman image tree" (piggybacking on
top of a "podman build" test, because that gives
us lots of layers).
- skip "podman exec - basic test" when remote. It is consistently
causing CI failures, breaking all of CI, due to #7241.

In local Podman, the frontend interprets the error and exit code
given by the Exec API to determine the appropriate exit code to
set for Podman itself; special cases like a missing executable
receive special exit codes.
Exec for the remote API, however, has to do this inside Libpod
itself, as Libpod will be directly queried (via the Inspect API
for exec sessions) to get the exit code. This was done correctly
when the exec session started properly, but we did not properly
handle cases where the OCI runtime fails before the exec session
can properly start. Making two error returns that would otherwise
not set exit code actually do so should resolve the issue.

podman-remote is in better shape now. Let's see what needs

- logs test: skip multilog, it doesn't work remote
- diff test: use -l only when local, not with remote
- many other tests: skip_if_remote, with 'FIXME: pending #xxxx'
where xxxx is a filed issue.
Unrelated: added new helper to skip_if_remote and _if_rootless,
where we check if the source message includes "remote"/"rootless"
and insert it if missing. This is a minor usability enhancement
to make it easier to understand at-a-glance why a skip triggers.

When copying from a URL, podman will download and create a context
directory in a temporary file. The problem was that this directory
was being removed as soon as the function that created it was returned.
Later the build code would look for content in the temporary directory
and fail to find it, blowing up the build.
By pulling the extraction code back into the build function, we keep the
temporary directory around until the build completes.

PR #6957 added a new path (/sys/devs) to an existing list
of masked mount points which an unprivileged container

those: run 'stat' on those devices in the container,
and make sure that they are dummies.
This is kind of kludgy, and relies on heuristics that
may not be 100% accurate. It also adds duplication,
a list that must be kept in sync with the original
list in pkg/specgen/generate/config_linux.go.
