Podman has, for a long time, had an internal concept of
dependency management, used mainly to ensure that pod infra
containers are started before any other container in the pod. We
also have the ability to recursively start these dependencies,
which we use to ensure that `podman start` on a container in a
pod will not fail because the infra container is stopped. We have
not, however, exposed these via the command line until now.
Add a `--requires` flag to `podman run` and `podman create` to
allow users to manually specify dependency containers. These
containers must be running before the container will start. Also,
make recursive starting with `podman start` default so we can
start these containers and their dependencies easily.

Initially I was missing transport information on podman manifest add.
Especially the `containers-storage` transport which references the
local image store. Had a use case where this came in quite handy and it
is not stated anywhere else in the docs. Suppose it does not make sense
for podman pull & push.
I've only added containers-storage and docker transports for
manifest add since I know those work. Maybe others work too.
I then also added the destination section to manifest push as it is done
in podman push & pull. I've added all transports here, but I don't know
if all are supported. Please review.

It is rare but possible that storage locations for the graphroot and the
runroot are not mounted at boot time, and therefore might race when
doing container operations. An example we've seen in the wild is that a
slow tmpfs mount for the runroot would suddenly mount over /run, causing
the container to lose all currently-running data, requiring a system
refresh to get it back.
This patch adds RequiresMountsFor= to the systemd.unit header to ensure
the paths for both the graphroot and runroot are mounted prior to
starting any generated unit files.

Backstory: every time you run 'make podman' or even
just 'make', you get a full recompile. This is sub-ideal.
Cause: I don't really know. It looks complicated. #5017
introduced a .PHONY for bin/podman, for reasons not
explained in the PR. Then, much later, #5880 well-
intentionedly but improperly tweaked the 'find'
command used in defining SOURCES, adding a -prune
but without the corresponding and required -print.
Let's just say, it was an unfortunate cascade of events.
This PR fixes the SOURCES definition and removes the
highly-undesired .PHONY from podman & podman-remote,
making it so you can type 'make' and, oh joy, not
build anything if it's current. The way 'make' is
supposed to work.
Why fix this now? Because my PR (#9209) was failing in CI,
in the Validate step:
Can't exec "./bin/podman": No such file or directory at hack/xref-helpmsgs-manpages line 223.
It failed even on Re-run, and only passed once I force-pushed
the PR (with no changes, just a new commit SHA). I have no idea
why bin/podman wasn't built, and I have zero interest in pursuing
that right now, but the proper solution is to add bin/podman as
a Makefile dependency for that particular test. So done.
While I'm at it, fix what is pretty clearly a typo in a .PHONY

Basic theory: We remove the container, but *only from the DB*.
We leave it in c/storage, we leave the lock allocated, we leave
it running (if it is). Then we create an identical container with
an altered name, and add that back to the database. Theoretically
we now have a renamed container.
The advantage of this approach is that it doesn't just apply to
rename - we can use this to make *any* configuration change to a
container that does not alter its container ID.
Potential problems are numerous. This process is *THOROUGHLY*
non-atomic at present - if you `kill -9` Podman mid-rename things
will be in a bad place, for example. Also, we can't rename
containers that can't be removed normally - IE, containers with
dependencies (pod infra containers, for example).
The largest potential improvement will be to move the majority of
the work into the DB, with a `RecreateContainer()` method - that
will add atomicity, and let us remove the container without
worrying about depencies and similar issues.
Potential problems: long-running processes that edit the DB and
may have an older version of the configuration around. Most
notable example is `podman run --rm` - the removal command needed
to be manually edited to avoid this one. This begins to get at
the heart of me not wanting to do this in the first place...
This provides CLI and API implementations for frontend, but no
tunnel implementation. It will be added in a future release (just
held back for time now - we need this in 3.0 and are running low
on time).
This is honestly kind of horrifying, but I think it will work.

This implements support for mounting and unmounting volumes
backed by volume plugins. Support for actually retrieving
plugins requires a pull request to land in containers.conf and
then that to be vendored, and as such is not yet ready. Given
this, this code is only compile tested. However, the code for
everything past retrieving the plugin has been written - there is
support for creating, removing, mounting, and unmounting volumes,
which should allow full functionality once the c/common PR is
merged.
A major change is the signature of the MountPoint function for
volumes, which now, by necessity, returns an error. Named volumes
managed by a plugin do not have a mountpoint we control; instead,
it is managed entirely by the plugin. As such, we need to cache
the path in the DB, and calls to retrieve it now need to access
the DB (and may fail as such).
Notably absent is support for SELinux relabelling and chowning
these volumes. Given that we don't manage the mountpoint for
these volumes, I am extremely reluctant to try and modify it - we
could easily break the plugin trying to chown or relabel it.
Also, we had no less than *5* separate implementations of
inspecting a volume floating around in pkg/infra/abi and
pkg/api/handlers/libpod. And none of them used volume.Inspect(),
the only correct way of inspecting volumes. Remove them all and
consolidate to using the correct way. Compat API is likely still
doing things the wrong way, but that is an issue for another day.

When migrating a container with associated volumes, the content of
these volumes should be made available on the destination machine.
This patch enables container checkpoint/restore with named volumes
by including the content of volumes in checkpoint file. On restore,
volumes associated with container are created and their content is
restored.
The --ignore-volumes option is introduced to disable this feature.
Example:
# podman container checkpoint --export checkpoint.tar.gz <container>
The content of all volumes associated with the container are included
in `checkpoint.tar.gz`
# podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container>
The content of volumes is not included in `checkpoint.tar.gz`. This is
useful, for example, when the checkpoint/restore is performed on the
same machine.
# podman container restore --import checkpoint.tar.gz
The associated volumes will be created and their content will be
restored. Podman will exit with an error if volumes with the same
name already exist on the system or the content of volumes is not
included in checkpoint.tar.gz
# podman container restore --ignore-volumes --import checkpoint.tar.gz
Volumes associated with container must already exist. Podman will not
create them or restore their content.

This adds a new command, 'podman network reload', to reload the
networks of existing containers, forcing recreation of firewall
rules after e.g. `firewall-cmd --reload` wipes them out.
Under the hood, this works by calling CNI to tear down the
existing network, then recreate it using identical settings. We
request that CNI preserve the old IP and MAC address in most
cases (where the container only had 1 IP/MAC), but there will be
some downtime inherent to the teardown/bring-up approach. The
architecture of CNI doesn't really make doing this without
downtime easy (or maybe even possible...).
At present, this only works for root Podman, and only locally.
I don't think there is much of a point to adding remote support
(this is very much a local debugging command), but I think adding
rootless support (to kill/recreate slirp4netns) could be
