when /proc is mounted with hidepid=1 a process doesn't see processes
from the outer user namespace. This causes an issue reading the
cmdline from the parent process.
To address it, always read the command line from /proc/self instead of
using /proc/PARENT_PID.

New hack/xref-helpmsgs-manpages script, added to CI 'gate'
task, runs 'podman [subcommand] --help' and cross-references
against man pages in docs/source/markdown/podman*.1.md
See #5453 and #5460 for instances of the problems the
script has found.
The careful reader will find an alarming number of special-case
bypasses. These are a tradeoff I am making: to get perfect
coverage with no handwaving, it would be necessary to make
drastic changes to some man pages, and I believe those would
be counterproductive.

This produces detailed information about the configuration of an
exec session in a format suitable for the new HTTP API.

As part of the rework of exec sessions, we need to address them
independently of containers. In the new API, we need to be able
to fetch them by their ID, regardless of what container they are
associated with. Unfortunately, our existing exec sessions are
tied to individual containers; there's no way to tell what
container a session belongs to and retrieve it without getting
every exec session for every container.
This adds a pointer to the container an exec session is
associated with to the database. The sessions themselves are
still stored in the container.
Exec-related APIs have been restructured to work with the new
database representation. The originally monolithic API has been
split into a number of smaller calls to allow more fine-grained
control of lifecycle. Support for legacy exec sessions has been
retained, but in a deprecated fashion; we should remove this in
a few releases.

As part of the rework of exec sessions, we want to split Create
and Start - and, as a result, we need to keep everything needed
to start exec sessions in the struct, not just the bare minimum
for tracking running ones.

Add support to auto-update containers running in systemd units as
generated with `podman generate systemd --new`.
`podman auto-update` looks up containers with a specified
"io.containers.autoupdate" label (i.e., the auto-update policy).
If the label is present and set to "image", Podman reaches out to the
corresponding registry to check if the image has been updated. We
consider an image to be updated if the digest in the local storage is
different than the one of the remote image. If an image must be
updated, Podman pulls it down and restarts the container. Note that the
restarting sequence relies on systemd.
At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT"
environment variables and stores it verbatim in the container's label.
This variable is now set by all systemd units generated by
`podman-generate-systemd` and is set to `%n` (i.e., the name of systemd
unit starting the container). This data is then being used in the
auto-update sequence to instruct systemd (via DBUS) to restart the unit
and hence to restart the container.
Note that this implementation of auto-updates relies on systemd and
requires a fully-qualified image reference to be used to create the
container. This enforcement is necessary to know which image to
actually check and pull. If we used an image ID, we would not know
which image to check/pull anymore.

1) 'podman system info' (in logcollector): has been silently
failing in special_testing_rootless, with:

Use ./bin/podman instead of just podman; this is probably
the right thing to do in the general case anyway
