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.

Tests for #7094, in which symlinks in a volume would
cause chown errors and nonrunnable containers.
Tests for environment variable precedence, now
include --env-host and proxy settings
Fix a bug caught by covscan in helpers.t ('source'
path would fail if path included spaces).
Fix podman-run man page: it was incorrect in stating
precedence between in-image environment and --env-host.

There are many use cases where you want to just mount an image
without creating a container on it. For example you might want
to just examine the content in an image after you pull it for
security analysys. Or you might want to just use the executables
on the image without running it in a container.
The image is mounted readonly since we do not want people changing
images.

We should default to the user name unmount rather then the internal
name of umount.
Also User namespace was not being handled correctly. We want to inform
the user that if they do a mount when in rootless mode that they have
to be first in the podman unshare state.

Bind-mounting /etc/passwd into the container is problematic
becuase of how system utilities like `useradd` work. They want
to make a copy and then rename to try to prevent breakage; this
is, unfortunately, impossible when the file they want to rename
is a bind mount. The current behavior is fine for read-only
containers, though, because we expect useradd to fail in those
cases.
Instead of bind-mounting, we can edit /etc/passwd in the
container's rootfs. This is kind of gross, because the change
will show up in `podman diff` and similar tools, and will be
included in images made by `podman commit`. However, it's a lot
better than breaking important system tools.

...or at least I hope it does. The symptom seems to be that
INTEGRATION_ROOT is not being defined in some code flows.
This PR blindly implements a suggestion from Miloslav,
setting INTEGRATION_ROOT in one more place.
We won't actually know for a long time if this works or
not, because the test failure is a flake.

Currently you can not apply an ApparmorProfile if you specify
--privileged. This patch will allow both to be specified
simultaniosly.
By default Apparmor should be disabled if the user
specifies --privileged, but if the user specifies --security apparmor:PROFILE,
with --privileged, we should do both.

The error messages from the 'podman xxx --help' cross-check
test are unhelpful, and cause much wasted time when they trigger.
Solution: instead of using the built-in exit-status check
in run_podman, do an explicit check outside of run_podman.
This lets us die() with a custom, hopefully useful, message.

Some CI tests are flaking in the SELinux test, possibly because
there's a new variation of the "multiple devices" warning I hadn't
seen before:
WARNING: Creating device "/dev/null" with same type, major and minor as existing "/dev/foodevdir/null".
Solution: in remove_same_dev_warning(), remove "multiple" from
the match string.
Also: fix a Go test that wasn't cleaning up after itself. And
add an actual test to it, not just check-exit-status.

Fix a potential panic in the events endpoint when parsing the filters
parameter. Values of the filters map might be empty, so we need to
account for that instead of uncondtitionally accessing the first item.
Also apply a similar for race conditions as done in commit f4a2d25c0f:
Fix a race that could cause read errors to be masked. Masking
such errors is likely to report red herrings since users don't
see that reading failed for some reasons but that a given event
could not be found.
Another race was the handler closing event channel, which could lead to
two kinds of panics: double close, send to close channel. The backend
takes care of that. However, make sure that the backend stops working
in case the context has been cancelled.

A newly-added test in #6835 was flaking in CI with:
not ok 143 [20-containers] DELETE libpod/containers/SHA
500 cannot remove container <sha> as it is running - running or paused containers cannot be removed without force: container state improper
Root cause: DELETE being run immediately after container start.
Although the container is short-lived, it does take time to
run and exit.
Solution: wait for container to exit (should be quick) before
deleting. This gives us a new test for the /wait endpoint.
Also: tweaked some comments for readability, removed unnecessary
container ps, added actual container status checks, and added
actual message checks to another test that was merely checking
exit status.

PR #6957 added a new path (/sys/devs) to an existing list
of masked mount points which an unprivileged container
should not be able to access. Here we add a test for
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.
I'd love to hear suggestions on how to do it better.

We already had special-case code to ignore than in the SELinux

I've refactored the "ignore this warning" code and written
