Say I start a container with the flag
`--runtime /usr/local/sbin/crun`. I then stop the container, and
restart it without the flag. We previously stored the runtime in
use by a container only by basename when given a path, so the
container only knows that it's using the `crun` OCI runtime - and
on being restarted without the flag, it will use the system crun,
not my special crun build.
Using the full path as the name in these cases ensures we will
still use the correct runtime, even on subsequent runs of Podman.

This allows us to run both the Libpod and Server handlers at the
same time without unregistering one.
Also, pass the signal that killed us into the handlers, in case
they want to use it to determine what to do (e.g. what exit code
to set).

Expand the use of the Shutdown package such that we now use it
to handle signals any time we run Libpod. From there, add code to
container creation to use the Inhibit function to prevent a
shutdown from occuring during the critical parts of container
creation.
We also need to turn off signal handling when --sig-proxy is
invoked - we don't want to catch the signals ourselves then, but
instead to forward them into the container via the existing
sig-proxy handler.

In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like
fails, the error message already contains the file name and the
operation that fails, so there is no need to wrap the error with
something like "open %s failed".
While at it
- replace a few places with os.Open, ioutil.ReadAll with
ioutil.ReadFile.
- replace errors.Wrapf with errors.Wrap for cases where there
are no %-style arguments.

The ListContainers API previously had a Pod parameter, which
determined if pod name was returned (but, notably, not Pod ID,
which was returned unconditionally). This was fairly confusing,
so we decided to deprecate/remove the parameter and return it
unconditionally.
To do this without serious performance implications, we need to
avoid expensive JSON decodes of pod configuration in the DB. The
way our Bolt tables are structured, retrieving name given ID is
actually quite cheap, but we did not expose this via the Libpod
API. Add a new GetName API to do this.

This was inspired by https://github.com/cri-o/cri-o/pull/3934 and
much of the logic for it is contained there. However, in brief,
a named return called "err" can cause lots of code confusion and
encourages using the wrong err variable in defer statements,
which can make them work incorrectly. Using a separate name which
is not used elsewhere makes it very clear what the defer should
be doing.
As part of this, remove a large number of named returns that were
not used anywhere. Most of them were once needed, but are no
longer necessary after previous refactors (but were accidentally
retained).

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].

* Support the `X-Registry-Auth` http-request header.
* The content of the header is a base64 encoded JSON payload which can
either be a single auth config or a map of auth configs (user+pw or
token) with the corresponding registries being the keys. Vanilla
Docker, projectatomic Docker and the bindings are transparantly
supported.
* Add a hidden `--registries-conf` flag. Buildah exposes the same
flag, mostly for testing purposes.
* Do all credential parsing in the client (i.e., `cmd/podman`) pass
the username and password in the backend instead of unparsed
credentials.
* Add a `pkg/auth` which handles most of the heavy lifting.
* Go through the authentication-handling code of most commands, bindings
and endpoints. Migrate them to the new code and fix issues as seen.
A final evaluation and more tests is still required *after* this
change.
* The manifest-push endpoint is missing certain parameters and should
use the ABI function instead. Adding auth-support isn't really
possible without these parts working.
* The container commands and endpoints (i.e., create and run) have not
been changed yet. The APIs don't yet account for the authfile.
* Add authentication tests to `pkg/bindings`.

After a restart, pods and containers both run a refresh()
function to prepare to run after a reboot. Until now, volumes
have not had a similar function, because they had no per-boot
setup to perform.
Unfortunately, this was not noticed when in-memory locking was
introduced to volumes. The refresh() routine is, among other
things, responsible for ensuring that locks are reserved after a
reboot, ensuring they cannot be taken by a freshly-created
container, pod, or volume. If this reservation is not done, we
can end up with two objects using the same lock, potentially
needing to lock each other for some operations - classic recipe
for deadlocks.
Add a refresh() function to volumes to perform lock reservation
and ensure it is called as part of overall refresh().

Refactor the `RuntimeConfig` along with related code from libpod into

This is a horrible hack to work around issues with Fedora 31, but
other distros might need it to, so we'll move it upstream.
I do not recommend this functionality for general use, and the
manpages and other documentation will reflect this. But for some
upgrade cases, it will be the only thing that allows for a
working system.

For future work, we need multiple implementations of the OCI
runtime, not just a Conmon-wrapped runtime matching the runc CLI.
As part of this, do some refactoring on the interface for exec
(move to a struct, not a massive list of arguments). Also, add
'all' support to Kill and Stop (supported by runc and used a bit
internally for removing containers).

This requires updating all import paths throughout, and a matching
buildah update to interoperate.
I can't figure out the reason for go.mod tracking
github.com/containers/image v3.0.2+incompatible // indirect
((go mod graph) lists it as a direct dependency of libpod, but
(go list -json -m all) lists it as an indirect dependency),
but at least looking at the vendor subdirectory, it doesn't seem
to be actually used in the built binaries.

If c/storage paths are explicitly set to "" (the empty string) it
will use compiled-in defaults. However, it won't tell us this via
`storage.GetDefaultStoreOptions()` - we just get the empty string
(which can put our defaults, some of which are relative to
c/storage, in a bad spot).
Hardcode a sane default for cases like this. Furthermore, add
some sanity checks to paths, to ensure we don't use relative
paths for core parts of libpod.
