Instead of unconditionally resetting to ContainerStateConfigured
after a reboot, allow containers in the Exited state to remain
there, preserving their exit code in podman ps after a reboot.
This does not affect the ability to use and restart containers
after a reboot, as the Exited state can be used (mostly)
interchangeably with Configured for starting and managing
containers.

We try to keep c.config immutable, but Go doesn't really agree
with me that things other than strings and ints can be immutable,
so occasionally things like this slip through.
When unmarshalling the OCI spec from disk, do it into a separate
struct, to ensure we don't make lasting modifications to the
spec in the Container struct (which could affect container
restart).

When waiting for a container, there is a long interval between
status checks - plenty long enough for the container in question
to start, then subsequently be cleaned up and returned to Created
state to be restarted. As such, we can't wait on container state
to go to Stopped or Exited - anything that is not Running or
Paused indicates the container is dead.

Add the ability to run the integration (ginkgo) suite using
the remote client.
Only the images_test.go file is run right now; all the rest are
isolated with a // +build !remotelinux. As more content is
developed for the remote client, we can unblock the files and
just block single tests as needed.

we can define multiple OCI runtimes that can be chosen with
--runtime.
in libpod.conf is possible to specify them with:
[runtimes]
foo = [
"/usr/bin/foo",
"/usr/sbin/foo",
]
bar = [
"/usr/bin/foo",
"/usr/sbin/foo",
]
If the argument to --runtime is an absolute path then it is used
directly without any lookup in the configuration.

This deprecates the libpod.conf variable of `runtime_path=`, and now has
`runtimes=`, like a map for naming the runtime, preparing for a
`--runtime` flag to `podman run` (i.e. runc, kata, etc.)

Finally, these members no longer have any users.
Future users should usually call referenceWithRegistry / normalizedReference,
and work with the returned value, instead of reintroducing these variables.
Similarly, direct uses of unnormalizedRef should be rare (only for cases
where the registry and/or path truly does not matter).

Image.MatchRepoTag and findImageInRepoTags do some kind of
heuristic search; the motivation and design of both, and how they
should deal with digests, is not obvious to me.
Instead of figuring that out now, just factor it out into a
scary-named method and leave the "tag" value (with its "latest"/"none"
value) alone.
Similarly, the .registry and .name fields should typically not be used;
users should use either hasRegistry or normalized reference types;
so, isolate the difficult-to-understand search code, and computation
of these values, into this new search-specific helper.

Again, rely on the official API, instead of the suprising "suspiciousTagValueForSearch"
value (set to :latest on untagged images, and :none on digested ones!)

not even syntatically valid, so this can't really be worse.
Still, maybe we should refuse to tag with digested references in the first place.

This shortens the code a bit, but most importantly ensures that all pulls from
docker.Transport are processed exactly the same way, and there is only a single
store.ParseStoreReference in the pull code.
It's a bit wasteful to call decompose() in getPullRefPair just after
pullGoalFromPossiblyUnqualifiedName has qualified the name, but on balance
only having exactly one code path seems worth it. Alternatively we could
split getPullRefPairToQualifiedDestination from getPullRefPair.

This bypasses .assemble, and preserves the original
lack of tag / original digest instead of adding :latest/:none
(still subject to ParseStoreReference normalization).
Using the original digest seems clearly correct; dropping the :latest
suffix from .image strings, and adding /library to docker.io/shortname,
only affects user-visible input; later uses of the return value of
pullImageFrom... use ParseStoreReference, which calls reference.ParseNormalizedNamed
and reference.TagNameOnly, so the image name should be processed
the same way whether it contains a tag, or libray/, or not.
This also allows us to drop the problematic hasShaInInputName heuristic/condition/helper.

CHANGES BEHAVIOR.
If the name is qualified, instead of decomposing it into components and
re-assembling, just use the input name unmodified:
- For name:tag values, .assemble() just recreates the input.
- For untagged values, .assemble() adds ":latest"; we keep
the input as is, but both docker.ParseReference and storage.Transport.ParseStoreReference
use reference.TagNameOnly() already.
- For digested references, .assemble() adds ":none", but
the code was already bypassing .assemble() on that path
already - for the source reference. For the destination,
this replaces a :none destination with a the @digest reference,
as expected.
Note that while decompose() has already parsed the input,
it (intentionally) bypassed the docker.io/library normalization;
therefore we parse the input again (via docker.ParseReference) to ensure
that the reference is normalized.
