Dealing with os.Signal channels seems more like an art than science
since signals may get lost. os.Notify doesn't block on an unbuffered
channel, so users are expected to know what they're doing or hope for
the best.
In the recent past, I've seen a number of flakes and BZs on non-amd64
architectures where I was under the impression that signals may got
lost, for instance, during stop and exec.
[NO TESTS NEEDED] since this is art.

When starting a process with `podman exec -it` the terminal is resized
after the process is started. To fix this allow exec start to accept the
terminal height and width as parameter and let it resize right before
the process is started.

Podman has, for a long time, had an internal concept of
dependency management, used mainly to ensure that pod infra
containers are started before any other container in the pod. We
also have the ability to recursively start these dependencies,
which we use to ensure that `podman start` on a container in a
pod will not fail because the infra container is stopped. We have
not, however, exposed these via the command line until now.
Add a `--requires` flag to `podman run` and `podman create` to
allow users to manually specify dependency containers. These
containers must be running before the container will start. Also,
make recursive starting with `podman start` default so we can
start these containers and their dependencies easily.

We missed bumping the go module, so let's do it now :)
* Automated go code with github.com/sirkon/go-imports-rename
* Manually via `vgrep podman/v2` the rest

The sig-proxy code is set up to error on failing to forward
signals to a container. This is reasonable in cases where the
container is running, but something strange went wrong - but when
the Kill fails because the container is stopped, we shouldn't
bother with aggressive Error logging since this is an expected
part of the container lifecycle - it stops, and then `podman run`
also stops, but there is a timing window in between where signals
will fail to be proxied, and we should not print angry errors
during that.

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.

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].

Add a new ContainerEngine method for creating a detached exec
session, and wire in the frontend code to do this. As part of
this, move Streams out of ExecOptions to the function signature
in an effort to share the struct between both methods.

While this commit was initially meant to fix #5847, it has turned into a
bigger refactoring which I did not manage to break into smaller pieces:
* Fix #5847 by refactoring the image-removal logic.
* Make the api handler for image-removal use the ABI code. This way,
both (i.e., ABI and Tunnel) end up using the same code. Achieving
this code share required to move some code around to prevent circular
dependencies.
* Everything in pkg/api (excluding pkg/api/types) must now only be
accessed from code using `ABISupport`.
* Avoid imports from entities on handlers to prevent circular
dependencies.
* Move `podman system service` logic into `cmd` to prevent circular
dependencies - it depends on pkg/api.
* Also remove the build header from infra/abi files. It will otherwise
confuse swagger and other tools; errors we cannot fix as go doesn't
expose a build-tag env variable.

add the ability to attach to a running container. the tunnel side of this is not enabled yet as we have work on the endpoints and plumbing to do yet.
add the ability to exec a command in a running container. the tunnel side is also being deferred for same reason.
