c4627b5846 Fix container and pod create commands for remote create
In `podman inspect` output for containers and pods, we include
the command that was used to create the container. This is also
used by `podman generate systemd --new` to generate unit files.

With remote podman, the generated create commands were incorrect
since we sourced directly from os.Args on the server side, which
was guaranteed to be `podman system service` (or some variant
thereof). The solution is to pass the command along in the
Specgen or PodSpecgen, where we can source it from the client's
os.Args.

This will still be VERY iffy for mixed local/remote use (doing a
`podman --remote run ...` on a remote client then a
`podman generate systemd --new` on the server on the same
container will not work, because the `--remote` flag will slip
in) but at the very least the output of `podman inspect` will be
correct. We can look into properly handling `--remote` (parsing
it out would be a little iffy) in a future PR.

09dc77aedf log API: add context to allow for cancelling
Add a `context.Context` to the log APIs to allow for cancelling
streaming (e.g., via `podman logs -f`).  This fixes issues for
the remote API where some go routines of the server will continue
writing and produce nothing but heat and waste CPU cycles.

8489dc4345 move go module to v2
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].

9e4cf6ca51 Fix system service panic from early hangup in events
We weren't actually halting the goroutine that sent events, so it
would continue sending even when the channel closed (the most
notable cause being early hangup - e.g. Control-c on a curl
session). Use a context to cancel the events goroutine and stop
sending events.

b20619e5b0 Allow recursive dependency start with Init()
As part of APIv2 Attach, we need to be able to attach to freshly
created containers (in ContainerStateConfigured). This isn't
something Libpod is interested in supporting, so we use Init() to
get the container into ContainerStateCreated, in which attach is
possible. Problem: Init() will fail if dependencies are not
started, so a fresh container in a fresh pod will fail. The
simplest solution is to extend the existing recursive start code
from Start() to Init(), allowing dependency containers to be
started when we initialize the container (optionally, controlled
via bool).

Also, update some comments in container_api.go to make it more
clear how some of our major API calls work.

118e78c5d6 Add structure for new exec session tracking to DB
As part of the rework of exec sessions, we need to address them
independently of containers. In the new API, we need to be able
to fetch them by their ID, regardless of what container they are
associated with. Unfortunately, our existing exec sessions are
tied to individual containers; there's no way to tell what
container a session belongs to and retrieve it without getting
every exec session for every container.

This adds a pointer to the container an exec session is
associated with to the database. The sessions themselves are
still stored in the container.

Exec-related APIs have been restructured to work with the new
database representation. The originally monolithic API has been
split into a number of smaller calls to allow more fine-grained
control of lifecycle. Support for legacy exec sessions has been
retained, but in a deprecated fashion; we should remove this in
a few releases.

e6c7ccc067 LibpodAPI.BuildImage: don't require a name for the new image
When we finish building an image, we try to look up its ID by looking up
the image using the name that we were asked to assign to the image.  If
we weren't asked to assign a name to the image, that would produce an
error.  The BuildImage() API we're using returns the image's ID anyway,
so we can skip the lookup and just return the ID directly.

1df4dba0a0 Switch to bufio Reader for exec streams
There were many situations that made exec act funky with input. pipes didn't work as expected, as well as sending input before the shell opened.
Thinking about it, it seemed as though the issues were because of how os.Stdin buffers (it doesn't). Dropping this input had some weird consequences.
Instead, read from os.Stdin as bufio.Reader, allowing the input to buffer before passing it to the container.

03da8b641d Rewrite backend for remote 'volume inspect'
We need to use the new Inspect() endpoint instead of trying to
JSON the actual volume structs. Currently, the output seems
completely nonsensical; it seems like we're JSONing the struct
for the Varlink connection itself? This should restore sanity and
match the format of remote and local inspect on volumes.

6f630bc09b Move OCI runtime implementation behind an interface
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).
