We are resolving the homedir of the user in many different
places. This Patch consolodates them to use container/storage
version.
This PR also fixes a failure mode when the homedir does not
exists, and the user sets a root path. In this situation
podman should continue to work. Podman does not require a users
homedir to exist in order to run.
Finally the rootlessConfigHomeDirOnce and rootlessRuntimeDirOnce
were broken, because if an error ever happened, they would not be recorded
the second time, and "" would be returned as the path.

As part of this, we need two new functions, for retrieving all
aliases for a network and removing all aliases for a network,
both required to test.
Also, rework handling for some things the tests discovered were
broken (notably conflicts between container name and existing
aliases).

When using multiple filters, return a volume that matches any one of the used filters, rather than matching both of the filters.
This is for compatibility with docker's cli, and more importantly, the apiv2 compat endpoint

When creating a container in a pod the podname was always set as
the dns entry. This is incorrect when the container is not part
of the pods network namespace. This happend both rootful and
rootless. To fix this check if we are part of the pods network
namespace and if not use the container name as dns entry.

Most of the builtin golang functions like os.Stat and
os.Open report errors including the file system object
path. We should not wrap these errors and put the file path
in a second time, causing stuttering of errors when they
get presented to the user.
This patch tries to cleanup a bunch of these errors.

Containers that share IPC Namespaces share each others
/dev/shm, which means a private /dev/shm needs to be setup
for the infra container.
Added a system test and an e2e test to make sure the
/dev/shm is shared.

Add a new "image" mount type to `--mount`. The source of the mount is
the name or ID of an image. The destination is the path inside the
container. Image mounts further support an optional `rw,readwrite`
parameter which if set to "true" will yield the mount writable inside
the container. Note that no changes are propagated to the image mount
on the host (which in any case is read only).
Mounts are overlay mounts. To support read-only overlay mounts, vendor
a non-release version of Buildah.

When the OCI Runtime tries to set certain settings in cgroups
it can get the error "no such file or directory", the wrapper
ends up reporting a bogus error like:
```
Request Failed(Internal Server Error): open io.max: No such file or directory: OCI runtime command not found error
{"cause":"OCI runtime command not found error","message":"open io.max: No such file or directory: OCI runtime command not found error","response":500}
```
On first reading of this, you would think the OCI Runtime (crun or runc) were not found. But the error is actually reporting
message":"open io.max: No such file or directory
Which is what we want the user to concentrate on.

If you use additional stores and pull the same image into
writable stores, you can end up with the situation where
you have the same image twice. This causes image exists
to return the wrong error. It should return true in this
situation rather then an error.

We only use this channel in terminal attach, and it was not a
buffered channel originally, so it would block on trying to send
unless a receiver was ready. In the non-terminal case, there was
no receiver, so attach blocked forever. Buffer the channel for a
single bool so that it will never block, even if unused.

The original interface only allowed retrieving aliases for a
specific network, not for all networks. This will allow aliases
to be retrieved for every network the container is present in,
in a single DB operation.

This adds the database backend for network aliases. Aliases are
additional names for a container that are used with the CNI
dnsname plugin - the container will be accessible by these names
in addition to its name. Aliases are allowed to change over time
as the container connects to and disconnects from networks.
Aliases are implemented as another bucket in the database to
register all aliases, plus two buckets for each container (one to
hold connected CNI networks, a second to hold its aliases). The
aliases are only unique per-network, to the global and
per-container aliases buckets have a sub-bucket for each CNI
network that has aliases, and the aliases are stored within that
sub-bucket. Aliases are formatted as alias (key) to container ID
(value) in both cases.
Three DB functions are defined for aliases: retrieving current
aliases for a given network, setting aliases for a given network,
and removing all aliases for a given network.

Add endpoints for the compat layer for network connect and disconnect. As of now, these two endpoints do nothing to change the network state of a container. They do some basic data verification and return the proper 200 response. This at least allows for scripts to work on the compatibility layer instead of getting 404s.

Make a distinction between pods that are completely running (all
containers running) and those that have some containers going,
but not all, by introducing an intermediate state between Stopped
and Running called Degraded. A Degraded pod has at least one, but
not all, containers running; a Running pod has all containers
running.

When a container either joins a pod that shares the network
namespace or uses `--net=container:` to share the network
namespace of another container, it does not have its own copy of
the CNI results used to generate `podman inspect` output. As
such, to inspect these containers, we should be going to the
container we share the namespace with for network info.
