The --env is used to add new environment variable to container or
override the existing one. The --unsetenv is used to remove
the environment variable.
It is done by sharing "env" and "unsetenv" flags between both
"update" and "create" commands and later handling these flags
in the "update" command handler.
The list of environment variables to add/remove is stored
in newly added variables in the ContainerUpdateOptions.
The Container.Update API call is refactored to take
the ContainerUpdateOptions as an input to limit the number of its
arguments.
The Env and UnsetEnv lists are later handled using the envLib
package and the Container is updated.
The remote API is also extended to handle Env and EnvUnset.

A lot of types are moved and now deprecated which causes lint issues.
IDResponse is copied into podman because that has no new 1 to 1
replacement. For some fields that we set as part of the docker API I
added the nolint directive as these fields might be used by API
consumers.
For the other types it is mostly a 1 to 1 move.
ParseUintList is deprecated but we can use the same function from
github.com/containers/storage/pkg/parsers instead.
Note that it containers breaking changes to pkg/bindings which we should
not do generally but given the prevoius commit already has a unavoidable
breaking change we might as well fix the IDResponse issue once now.

Update to the latest c/{common,image} which inclused an update to
docker v28, that update is NOT backwards compatible so I had to fix a
few types.
NOTE: handler.ExecCreateConfig is used directly by the bindings. Thus
this is an API break for pkg/bindings. Including docker types as part of
any stable pkg/bindings API was a very bad idea.
I see no way to avoid that unless we never want to docker v28, which is
not easy as the update comes in from c/image and maybe other packages.

podman exec support detaching early via the detach key sequence. In that
case the podman process should exit successfully but the container exec
process keeps running.
Now I wrote automated test for both podman run and exec detach but this
uncovered several larger issues:
- detach sequence parsing is broken[1]
- podman-remote exec detach is broken[2]
- detach in general seems to be buggy/racy, seeing lot of flakes that
fail to restore the terminal and get an EIO instead, i.e.
"Unable to restore terminal: input/output error"
Thus I cannot add tests for now but this commit should at least fix the
obvoius case as reported by the user so I like to get this in regardless
and I will work through the other issues once I have more time.

The `podman system prune` command is able to remove build containers that were created during the build, but were not removed because the build terminated unexpectedly.
By default, build containers are not removed to prevent interference with builds in progress. Use the **--build** flag when running the command to remove build containers as well.

New flags in a `podman update` can change the configuration of HealthCheck when the container is started, without having to restart or recreate the container.
This can help determine why a given container suddenly started failing HealthCheck without interfering with the services it provides. For example, reconfigure HealthCheck to keep logs longer than the usual last X results, store logs to other destinations, etc.

If volume ls was called while another volume was removed at the right
time it could have failed with "no such volume" as we did not ignore
such error during listing. As we list things and this no longer exists
the correct thing is to ignore the error and continue like we do with
containers, pods, etc...
This was pretty easy to reproduce with these two commands running in
different terminals:
while :; do bin/podman volume create test && bin/podman volume rm test || break; done
while :; do bin/podman volume ls || break ; done

One of the problems with the Events() API was that you had to call it in
a new goroutine. This meant the the error returned by it had to be read
back via a second channel. This cuased other bugs in the past but here
the biggest problem is that basic errors such as invalid since/until
options were not directly returned to the caller.
It meant in the API we were not able to write http code 200 quickly
because we always waited for the first event or error from the
channels. This in turn made some clients not happy as they assume the
server hangs on time out if no such events are generated.
To fix this we resturcture the entire event flow. First we spawn the
goroutine inside the eventer Read() function so not all the callers have
to. Then we can return the basic error quickly without the goroutine.
The caller then checks the error like any normal function and the API
can use this one to decide which status code to return.
Second we now return errors/event in one channel then the callers can
decide to ignore or log them which makes it a bit more clear.

The special handling to return the exit code after the container has
been removed should only be done if there are no special conditions
requested. If a user asked for running or nay other state returning the
exit code immediately with a success response is just wrong. We only
want to allow that so the remote client can fetch the exit code without
races.

Prior to this commit, many scp functions existed without option structs, which would make extending functionality (adding new options) impossible without breaking changes, or without adding redundant wrapper functions.
This commit adds in new option types for various scp related functions, and changes those functions' signatures to use the new options.
This commit also modifies the `ImageEngine.Scp()` function's interface to use the new opts.
The commit also renames the existing `ImageScpOptions` entity type to `ScpTransferImageOptions`. This is because the previous `ImageScpOptions` was inaccurate, as it is not the actual options for `ImageEngine.Scp()`. `ImageEngine.Scp()` should instead receive `ImageScpOptions`.
This commit should not change any behavior, however it will break the existing functions' signatures.

In the common scenario of podman-remote run --rm the API is required to
attach + start + wait to get exit code. This has the problem that the
wait call races against the container removal from the cleanup process
so it may not get the exit code back. However we keep the exit code
around for longer than the container so we can just look it up in the
endpoint. Of course this only works when we get a full id as param but
podman-remote will do that.

Currently podman run -d can exit 0 if we send SIGTERM during startup
even though the contianer was never started. That just doesn't make any
sense is horribly confusing for a external job manager like systemd.
The original motivation was to exit 0 for the podman.service in commit
ca7376bb11. That does make sense but it should only do so for the
service and only if the server did indeed gracefully shutdown.
So we rework how the exit logic works, do not let the handler perform
the exit. Instead the shutdown package does the exit after all handlers
are run, this solves the issue of ordering. Then we default to exit code
1 like we did before and allow the service exit handler to overwrite the
exit code 0 in case of a graceful shutdown.

These flags can affect the output of the HealtCheck log. Currently, when a container is configured with HealthCheck, the output from the HealthCheck command is only logged to the container status file, which is accessible via `podman inspect`.
It is also limited to the last five executions and the first 500 characters per execution.
This makes debugging past problems very difficult, since the only information available about the failure of the HealthCheck command is the generic `healthcheck service failed` record.
- The `--health-log-destination` flag sets the destination of the HealthCheck log.
- `none`: (default behavior) `HealthCheckResults` are stored in overlay containers. (For example: `$runroot/healthcheck.log`)
- `directory`: creates a log file named `<container-ID>-healthcheck.log` with JSON `HealthCheckResults` in the specified directory.
- `events_logger`: The log will be written with logging mechanism set by events_loggeri. It also saves the log to a default directory, for performance on a system with a large number of logs.
- The `--health-max-log-count` flag sets the maximum number of attempts in the HealthCheck log file.
- A value of `0` indicates an infinite number of attempts in the log file.
- The default value is `5` attempts in the log file.
- The `--health-max-log-size` flag sets the maximum length of the log stored.
- A value of `0` indicates an infinite log length.
- The default value is `500` log characters.

We were only splitting on tabs, not spaces, so we returned just a
single line most of the time, not an array of the fields in the
output of `ps`. Unfortunately, some of these fields are allowed
to contain spaces themselves, which makes things complicated, but
we got lucky in that Docker took the simplest possible solution
and just assumed that only one field would contain spaces and it
would always be the last one, which is easy enough to duplicate
on our end.
