This results in some functionality changes:
If a ErrCtrStateInvalid is returned to GetPodStats, the container is ommitted from the stats.
As such, if an empty slice of Container stats are returned to GetPodStats in varlink, an error will occur.
GetContainerStats will return the ErrCtrStateInvalid as well.
Finally, if ErrCtrStateInvalid is returned to the podman stats call, the container will be ommitted from the stats.

This removes some boilerplate from the libpod package, so we can focus
on container stuff there. And it gives us a tidy sub-package for
focusing on ctime extraction, so we can focus on unit testing and
portability of the extraction utility there.
For the unsupported implementation, I'm falling back to Go's ModTime
[1]. That's obviously not the creation time, but it's likely to be
closer than the uninitialized Time structure from cc6f0e85 (more
changes to compile darwin, 2018-07-04, #1047). Especially for our use
case in libpod/oci, where we're looking at write-once exit files.
The test is more complicated than I initially expected, because on
Linux filesystem timestamps come from a truncated clock without
interpolation [2] (and network filesystems can be completely decoupled
[3]). So even for local disks, creation times can be up to a jiffie
earlier than 'before'. This test ensures at least monotonicity by
creating two files and ensuring the reported creation time for the
second is greater than or equal to the reported creation time for the
first. It also checks that both creation times are within the window
from one second earlier than 'before' through 'after'. That should be
enough of a window for local disks, even if the kernel for those
systems has an abnormally large jiffie. It might be ok on network
filesystems, although it will not be very resilient to network clock
lagging behind the local system clock.

* Clear the environment when the hook doesn't set 'env'. The runtime
spec has [1]:
> * env (array of strings, OPTIONAL) with the same semantics as IEEE
> Std 1003.1-2008's environ.
And running execle or similar with NULL env results in an empty
environment:
$ cat test.c
#include <unistd.h>
int main()
{
return execle("/usr/bin/env", "env", NULL, NULL);
}
$ cc -o test test.c
$ ./test
...no output...
Go's Cmd.Env, on the other hand, has [2]:
> If Env is nil, the new process uses the current process's environment.
This commit works around that by setting []string{} in those cases
to avoid leaking the runtime environment into the hooks.
* Roll the 'timeout' value (if set) into the passed context. There's
no need for two separate ways to cancel hook execution.
* Add a configurable timeout on abandoning a post-kill wait. The
waiting goroutine will continue and eventually reap the process, but
this avoids blocking the Run() call when that takes inordinately
long (for example, if a GPU cleanup hook is stuck in I/O sleep [3]).
The 'env' output format is specified in POSIX [4].

This isn't an issue with podman, which will only ever use one
directory. But CRI-O generally uses two directories, and we want to
make sure that changes to the fallback directory are not clobbering
hooks configured in the override directory. More background in [1].
I've split the handling into a single-directory block and a
multiple-directory block so we don't waste time polling the filesystem
for single-directory removals.
I'm using the single-directory block for the the zero-directory case
as well. Managers with zero directories should not be receiving
fsnotify events, so I don't think it really matters which block
handles them. If we want to handle this case robustly (because we're
concerned about something in the hook package adjusted the private
.directories property on the fly?), then we'll probably want to add an
explicit zero-directory block in future work.

This allows us to reference the hooks docs from podman(1) in a way
that will survive system installation. The downside is that the
GitHub rendered pages become less usable, now that we can no longer
embed links as freely as we could before.
I've followed the "Sections within a manual page" suggestions from
[1].
locale(7) is [2], which is Linux-specific. Even section numbering is
platform-dependent [3], so it's unlikely that these external man
references are particularly portable. Platform packagers can adjust
our local references to match their target system, but that leaves the
GitHub rendering in an awkward place. For now, I think a
Linux-centric GitHub rendering without clickable links may be the best
we can do without moving away from go-md2man.
As far as I can tell, there's not a nice way to get go-md2man to wrap
the links in SEE ALSO without sometimes hyphenating a URL (which makes
it harder for man-page readers to copy/paste those links into their
browser).
I've also fixed some "extention" -> "extension" typos.

This shifts the matching logic out of libpod/container_internal and
into the hook package, where we can reuse it after vendoring into
CRI-O. It also adds unit tests with almost-complete coverage. Now
libpod is even more isolated from the hook internals, which makes it
fairly straightforward to bump the hook config file to 1.0.0. I've
dubbed the old format 0.1.0, although it doesn't specify an explicit
version. Motivation for some of my changes with 1.0.0:
* Add an explicit version field. This will make any future JSON
structure migrations more straightforward by avoiding the need for
version-guessing heuristics.
* Collect the matching properties in a new When sub-structure. This
makes the root Hook structure easier to understand, because you
don't have to read over all the matching properties when wrapping
your head around Hook.
* Replace the old 'hook' and 'arguments' with a direct embedding of
the runtime-spec's hook structure. This provides access to
additional upstream properties (args[0], env, and timeout) and
avoids the complication of a CRI-O-specific analog structure.
* Add a 'when.always' property. You can usually accomplish this
effect in another way (e.g. when.commands = [".*"]), but having a
boolean explicitly for this use-case makes for easier reading and
writing.
* Replace the previous annotations array with an annotations map. The
0.1.0 approach matched only the values regardless of key, and that
seems unreliable.
* Replace 'cmds' with 'when.commands', because while there are a few
ways to abbreviate "commands", there's only one way to write it out
in full ;). This gives folks one less thing to remember when
writing hook JSON.
* Replace the old "inject if any specified condition matches" with
"inject if all specified conditions match". This allows for more
precise targeting. Users that need more generous targeting can
recover the previous behavior by creating a separate 1.0.0 hook file
for each specified 0.1.0 condition.
I've added doc-compat support for the various pluralizations of the
0.1.0 properties. Previously, the docs and code were not in
agreement. More on this particular facet in [1].
I've updated the docs to point out that the annotations being matched
are the OCI config annotations. This differs from CRI-O, where the
annotations used are the Kubernetes-supplied annotations [2,3]. For
example, io.kubernetes.cri-o.Volumes [4] is part of CRI-O's runtime
config annotations [5], but not part of the Kubernetes-supplied
annotations CRI-O uses for matching hooks.
The Monitor method supports the CRI-O use-case [6]. podman doesn't
need it directly, but CRI-O will need it when we vendor this package
there.
I've used nvidia-container-runtime-hook for the annotation examples
because Dan mentioned the Nvidia folks as the motivation behind
annotation matching. The environment variables are documented in [7].
The 0.1.0 hook config, which does not allow for environment variables,
only works because runc currently leaks the host environment into the
hooks [8]. I haven't been able to find documentation for their usual
annotation trigger or hook-install path, so I'm just guessing there.

first pass at adding in the container related endpoints/methods for the libpod
backend. Couple of important notes:
* endpoints that can use a console are not going to be done until we have "remote" console
* several of the container methods should probably be able to stream as opposed to a one-off return

The secrets code was just tarring and copying the contents of the secrets directory on host as is.
This meant it was not accounting for any symlinks inside the directory, leading up to the contents

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.

Previous code was using slow routines to collect some of the information
needed to output images. Specifically size was being calculated instead
of using the cached, already known size already available. Also, straight-
lined several of the code paths. Overall assessment is that these
improvements cut the time for images in half.
