split the generation for the default storage.conf and when we write it
if not existing for a rootless user.
This is necessary because during the startup we might be overriding
the default configuration through --storage-driver and --storage-opt,
that would not be written down to the storage.conf file we generated.

when the fallback is in place, the first user creating /tmp/user/$EUID
prevents other users for creating other directories since /tmp/user is
created with mode 0700.
Since there is no way for an unprivileged user to initialize the
/tmp/user directory correctly (we would need it to be owned by root
with the sticky bit set), let's just use /tmp/libpod-rundir-$EUID.

In lipod, we now log major events that occurr. These events
can be displayed using the `podman events` command. Each
event contains:
* Type (container, image, volume, pod...)
* Status (create, rm, stop, kill, ....)
* Timestamp in RFC3339Nano format
* Name (if applicable)
* Image (if applicable)
The format of the event and the varlink endpoint are to not
be considered stable until cockpit has done its enablement.

No reason to do it in util/ anymore. It's always going to be a
subdirectory of c/storage graph root by default, so we can just
set it after the return.

There are some cases where we might not be properly adjusting the
volume path after setting the storage graph root. Ensure that we
always set volume path to be a child of graph root.

iFix builtin volumes to work with podman volume
Currently builtin volumes are not recored in podman volumes when
they are created automatically. This patch fixes this.
Remove container volumes when requested
Currently the --volume option on podman remove does nothing.
This will implement the changes needed to remove the volumes
if the user requests it.
When removing a volume make sure that no container uses the volume.

Due to our unconditionally setting some storage options, we
are not always reading storage options from storage.conf. This
can lead to some fields in the storage config (most notably extra
storage options) being ignored, despite being set in
storage.conf.
Resolve this by unconditionally refreshing our storage config
from storage.conf (this was previously only done for rootless
Podman)
Fixes #2217

For rootless Podman, if storage.conf exists but does not specify
one or both of RunRoot and GraphRoot, set them to rootless
defaults so we don't end up with an unusable configuration.

Users have no idea what storage configuration file is used to setup
storage, so adding this to podman info, should make it easier to
discover.
This requires a revendor of containers/storage

Add support for podman volume and its subcommands.
The commands supported are:
podman volume create
podman volume inspect
podman volume ls
podman volume rm
podman volume prune
This is a tool to manage volumes used by podman. For now it only handle
named volumes, but eventually it will handle all volumes used by podman.

We don't need this for anything more than rootless work in Libpod
now, but Buildah still uses it as it was originally written, so
leave it intact as part of our API.

Previous commits ensured that we would use database-configured
paths if not explicitly overridden.
However, our runtime generation did unconditionally override
storage config, which made this useless.
Move rootless storage configuration setup to libpod, and change
storage setup so we only override if a setting is explicitly
set, so we can still override what we want.

do not store the entire file but only the subset of what we have
modified. Also, we were not writing the correct data. Since it is
not trivial to serialize storage.conf correctly and all the various
supported options, serialize only what we care about.

If fuse-overlayfs is present, rootless containers default to use it.
This can still be overriden either via the command line with
--storage-driver or in the ~/.config/containers/storage.conf
configuration file.

we are currently using something like /run/user/UID/run as runroot, as
it is already done by Buildah. This ends up with
/run/user/UID/run/runc for the runc directory. Change to drop the
additional /run so that runc will use /run/user/UID/runc.

also, created a first pass at a libpodpy package which will stand as a client to

This represents the stage3 implementation for the image library. At this point, we
are moving the image-centric functions to pkg/image including migration of args and
object-oriented references. This is a not a one-for-one migration of funcs and some
funcs will need to continue to reside in runtime_img as they are overly specific to
libpod and probably not useful to others.
