instead of opening directly the UNIX socket path, grab a reference to
it through a O_PATH file descriptor and use the fixed size string
"/proc/self/fd/%d" to open the UNIX socket. In this way it won't hit
the 108 chars length limit.

This PR takes the settings from containers.conf and uses
them. This works on the podman local but does not fix the
issue for podman remote or for APIv2. We need a way
to specify optionalbooleans when creating containers.

In 2.2.x, we moved `play kube` to use the Start() API for pods,
which reported errors in a different way (all containers are
started in parallel, and then results reported as a block). The
migration attempted to preserve compatibility by returning only
one error, but that's not really a viable option as it can
obscure the real reason that a pod is failing. Further, the code
was not correctly handling the API's errors - Pod Start() will,
on any container error, return a map of container ID to error
populated for all container errors *and* return ErrPodPartialFail
for overall error - the existing code did not handle the partial
failure error and thus would never return container errors.
Refactor the `play kube` API to include a set of errors for
containers in each pod, so we can return all errors that occurred
to the frontend and print them for the user, and correct the
backend code so container errors are actually forwarded.

Currently if server is not connected, we return an error message that
is confusing users on Mac and Windows boxes. The hope here is to make
it a little easier to discover that a Podman service is required.
This message is similar to what Docker puts out so people might under
stand it better.

Due to various reasons, CI results (esp. testing tasks) are completely
ignored for builds triggered by a new tag-push. Additionally, since
many of the automation scripts are in the repo., any related
failures/flakes would require code changes (therefore a new tag).
Resolve this by skipping every testing-type task for builds triggered by
tag-push. Only retain tasks which build things intended for consumption
associated with a possible official release.

Follow-up to commit (1ad796677e). The build on mips is still
failing because SIGWINCH was not defined in the signal pkg.
Also stat_t.Rdev is unit32 on mips so we need to typecast.

When I launch a container with --userns=keep-id the rootless processes
should have no caps by default even if I launch the container with
--privileged. It should only get the caps if I specify by hand the
caps I want leaked to the process.
Currently we turn off capeff and capamb, but not capinh. This patch
treats capinh the same way as capeff and capamb.

First, use the pflag library to parse the flags. With this we can
handle all corner cases such as -td or --detach=false.
Second, preserve the root args with --new. They are used for all podman
commands in the unit file. (e.g. podman --root /tmp run alpine)

writing to the id map fails when an extent overlaps multiple mappings
in the parent user namespace:
$ cat /proc/self/uid_map
0 1000 1
1 100000 65536
$ unshare -U sleep 100 &
[1] 1029703
$ printf "0 0 100\n" | tee /proc/$!/uid_map
0 0 100
tee: /proc/1029703/uid_map: Operation not permitted
This limitation is particularly annoying when working with rootless
containers as each container runs in the rootless user namespace, so a
command like:
$ podman run --uidmap 0:0:2 --rm fedora echo hi
Error: writing file `/proc/664087/gid_map`: Operation not permitted: OCI permission denied
would fail since the specified mapping overlaps the first
mapping (where the user id is mapped to root) and the second extent
with the additional IDs available.
Detect such cases and automatically split the specified mapping with
the equivalent of:
$ podman run --uidmap 0:0:1 --uidmap 1:1:1 --rm fedora echo hi
hi
A fix has already been proposed for the kernel[1], but even if it
accepted it will take time until it is available in a released kernel,
so fix it also in pkg/rootless.

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.

Instead of specifying restore option arguments individually from
RestoreOptions, provide the 'options' object to the CRImportCheckpoint
method. This change makes the code in CRImportCheckpoint easier to
extend as it doesn't require excessive number of function parameters.
