When using the docker REST API to wait for a container to be removed,
for example, WaitContainerDocker uses a one microsecond interval between
poll requests. This ends up being effectively a busy-wait, with the
podman system service spinning at > 100% CPU time.
The equivalent Podman method uses a 250ms default. Use that for the
docker variant, too.
I'm going to optimistically assert [NO NEW TESTS NEEDED] - given there's
no functional change here, and a test will require some form of mocking
or strac'ing the binary for evidence that it's polling less frequently,
unless someone who is familiar with podman can briefly explain what kind

Conceptually equivalent to networking by means of slirp4netns(1),
with a few practical differences:
- pasta(1) forks to background once networking is configured in the
namespace and quits on its own once the namespace is deleted:
file descriptor synchronisation and PID tracking are not needed
- port forwarding is configured via command line options at start-up,
instead of an API socket: this is taken care of right away as we're
about to start pasta
- there's no need for further selection of port forwarding modes:
pasta behaves similarly to containers-rootlessport for local binds
(splice() instead of read()/write() pairs, without L2-L4
translation), and keeps the original source address for non-local
connections like slirp4netns does
- IPv6 is not an experimental feature, and enabled by default. IPv6
port forwarding is supported
- by default, addresses and routes are copied from the host, that is,
container users will see the same IP address and routes as if they
were in the init namespace context. The interface name is also
sourced from the host upstream interface with the first default
route in the routing table. This is also configurable as documented
- sandboxing and seccomp(2) policies cannot be disabled
- only rootless mode is supported.
See https://passt.top for more details about pasta.
Also add a link to the maintained build of pasta(1) manual as valid
in the man page cross-reference checks: that's where the man page
for the latest build actually is -- it's not on Github and it doesn't
match any existing pattern, so add it explicitly.

implement new ssh interface into podman
this completely redesigns the entire functionality of podman image scp,
podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh
have been moved to common as have native ssh/scp execs and the new usage of the sftp package.
this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default.
Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the
ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production.
The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used.
podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls.
My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.

Some background for this PR is in discussion #14641. In short, ever so often a container inspect will return a `status.status` of `initialized` from the Docker compat socket.
From the discussion I found these lines which tries to fix a "configured" status to "created".
c936d1e611/pkg/api/handlers/compat/containers.go (L291-L294)
However, commit 141de86862 (Revamp Libpod state strings for Docker compat) removed the "configured" return value from the `String()` method called on line 291 above. Thus, making the `if` check redundant as it will never hit. But the same commit also introduces a return for "initialized" which this `if` should probably have been adapted for.

add support for podman-remote image scp as well as direct access via the API. This entailed
a full rework of the layering of image scp functions as well as the usual API plugging and type creation
also, implemented podman image scp tagging. which makes the syntax much more readable and allows users t tag the new image
they are loading to the local/remote machine:
allow users to pass a "new name" for the image they are transferring
`podman tag` as implemented creates a new image im `image list` when tagging, so this does the same
meaning that when transferring images with tags, podman on the remote machine/user will load two images
ex: `podman image scp computer1::alpine computer2::foobar` creates alpine:latest and localhost/foobar on the remote host
implementing tags means removal of the flexible syntax. In the currently released podman image scp, the user can either specify
`podman image scp source::img dest::` or `podman image scp dest:: source::img`. However, with tags this task becomes really hard to check
which is the image (src) and which is the new tag (dst). Removal of that streamlines the arg parsing process

This commit addresses three intertwined bugs to fix an issue when using
Gitlab runner on Podman. The three bug fixes are not split into
separate commits as tests won't pass otherwise; avoidable noise when
bisecting future issues.
1) Podman conflated states: even when asking to wait for the `exited`
state, Podman returned as soon as a container transitioned to
`stopped`. The issues surfaced in Gitlab tests to fail [1] as
`conmon`'s buffers have not (yet) been emptied when attaching to a
container right after a wait. The race window was extremely narrow,
and I only managed to reproduce with the Gitlab runner [1] unit
tests.
2) The clearer separation between `exited` and `stopped` revealed a race
condition predating the changes. If a container is configured for
autoremoval (e.g., via `run --rm`), the "run" process competes with
the "cleanup" process running in the background. The window of the
race condition was sufficiently large that the "cleanup" process has
already removed the container and storage before the "run" process
could read the exit code and hence waited indefinitely.
Address the exit-code race condition by recording exit codes in the
main libpod database. Exit codes can now be read from a database.
When waiting for a container to exit, Podman first waits for the
container to transition to `exited` and will then query the database
for its exit code. Outdated exit codes are pruned during cleanup
(i.e., non-performance critical) and when refreshing the database
after a reboot. An exit code is considered outdated when it is older
than 5 minutes.
While the race condition predates this change, the waiting process
has apparently always been fast enough in catching the exit code due
to issue 1): `exited` and `stopped` were conflated. The waiting
process hence caught the exit code after the container transitioned
to `stopped` but before it `exited` and got removed.
3) With 1) and 2), Podman is now waiting for a container to properly
transition to the `exited` state. Some tests did not pass after 1)
and 2) which revealed the third bug: `conmon` was executed with its
working directory pointing to the OCI runtime bundle of the
container. The changed working directory broke resolving relative
paths in the "cleanup" process. The "cleanup" process error'ed
before actually cleaning up the container and waiting "main" process
ran indefinitely - or until hitting a timeout. Fix the issue by
executing `conmon` with the same working directory as Podman.
Note that fixing 3) *may* address a number of issues we have seen in the
past where for *some* reason cleanup processes did not fire.

* Replace "setup", "lookup", "cleanup", "backup" with
"set up", "look up", "clean up", "back up"
when used as verbs. Replace also variations of those.
* Improve language in a few places.

use the memory limit specified for the container instead of reading it
from the cgroup. It is not reliable to read it from the cgroup since
the container could have been moved to a different cgroup and in
general the OCI runtime might create a sub-cgroup (like crun does).

When we return no containers we just return `[]` but we still have to keep
the content type header `application/json` so external tools can correctly
parse the output.
