When we already know the resulting slice size but still need/want to use
append, it makes sense to preallocate the slice by using make with the
capacity argument.
This commit is part of series fixing issues reported by prealloc linter
from golangci-lint v2.8.0.

Calling append can lead to resizing the slice. In case we have all
elements beforehand, it is not necessary to call append in the first
place and this avoid resizing.
This is the first part of fixing issues reported by prealloc linter from
golangci-lint v2.8.0.

For use cases like HPC, where `podman exec` is called in rapid succession, the standard exec process can become a bottleneck due to container locking and database I/O for session tracking.
This commit introduces a new `--no-session` flag to `podman exec`. When used, this flag invokes a new, lightweight backend implementation that:
- Skips container locking, reducing lock contention
- Bypasses the creation, tracking, and removal of exec sessions in the database
- Executes the command directly and retrieves the exit code without persisting session state
- Maintains consistency with regular exec for container lookup, TTY handling, and environment setup
- Shares implementation with health check execution to avoid code duplication
The implementation addresses all performance bottlenecks while preserving compatibility with existing exec functionality including --latest flag support and proper exit code handling.
Changes include:
- Add --no-session flag to cmd/podman/containers/exec.go
- Implement lightweight execution path in libpod/container_exec.go
- Ensure consistent container validation and environment setup
- Add comprehensive exit code testing including signal handling (exit 137)
- Optimize configuration to skip unnecessary exit command setup

Tremendous amount of changes in here, but all should amount to
the same thing: changing Go import paths from v5 to v6.
Also bumped go.mod to github.com/containers/podman/v6 and updated
version to v6.0.0-dev.

Problem: While removing cgroupsv1 code, I noticed my neovim Go config
automatically changed fileperms to the new octal format and I didn't
want that polluting my diffs.
Decision: I thought it best to switch to the new octal format in a dedicated PR.
Action:
- Cursor switched to new octal format for all fileperm ocurrences in Go
source and test files.
- vendor/, docs/ and non-Go files were ignored.
- Reviewed manually.

Add --creds flag to podman create and podman run commands to support

Allow users to target the most recently created container with
`podman update --latest` (short `-l`). The same option already exists
on many other commands, so this brings update in line with the rest of
the CLI and saves users from typing or looking up the newest container.

If the --health-cmd flag is not specified, other flags such as --health-interval, --health-timeout, --health-retries, and --health-start-period are ignored if the image contains a Healthcheck. This makes it impossible to modify these Healthcheck configuration when a container is created.

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.

Since commit c25cc7230 ("Allow a value of -1 to set unlimited pids
limit") podman converts the pids-limit value of -1 to 0 for OCI spec.
Unfortunately, different runtimes (crun and runc) treat pids.limit=0
differently, and the runtime-spec definition is somewhat vague
(see [1]).
Long term fix belongs to runtime-spec and then runtimes should follow
it.
Short term fix is do not convert -1 to 0 (as all runtimes treat -1 as
unlimited).
[NO NEW TESTS NEEDED] -- this is covered by test added in commit 553e53d44.

The PodmanOptionsKey is never used anywhere so it is pointless to add
this. Second having several functions to return the same context makes
no sense so fold them all into one. Lastly create the context once and
always return the same one instead of having to nil check each time.

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.

This fixes two problems, first if a port is published and exposed it
should not be shown twice. It is enough to show the published one.
Second, if there is a huge range the ports were no grouped causing the
output to be unreadable basically. Now we group exposed ports like we do
with the normal published ports.

The podman container cleanup process runs asynchronous and by the time
it gets the lock it is possible another podman process already did the
cleanup and then did a new init() to start it again. If the cleanup
process gets the lock there it will cause very weird things.
This can be observed in the remote start API as CI flakes.

When we use passthrough logging and the --rmi option should not try to

Since commit 458ba5a8af the cleanup process now removes the image as
well, thus the removal is racy and it will cause an error here.
The code tried to ignore the error with errors.Is() but this never works
across the remote API. However the API already has a ignore option so
juts use that and fix the error message so that we can easily find the
root cause and I do not have to guess where the log was written.

This started off as an attempt to make `podman stop` on a
container started with `--rm` actually remove the container,
instead of just cleaning it up and waiting for the cleanup
process to finish the removal.
In the process, I realized that `podman run --rmi` was rather
broken. It was only done as part of the Podman CLI, not the
cleanup process (meaning it only worked with attached containers)
and the way it was wired meant that I was fairly confident that
it wouldn't work if I did a `podman stop` on an attached
container run with `--rmi`. I rewired it to use the same
mechanism that `podman run --rm` uses, so it should be a lot more
durable now, and I also wired it into `podman inspect` so you can
tell that a container will remove its image.
Tests have been added for the changes to `podman run --rmi`. No
tests for `stop` on a `run --rm` container as that would be racy.

The new golangci-lint version 1.60.1 has problems with typecheck when
linting remote files. We have certain pakcages that should never be
inlcuded in remote but the typecheck tries to compile all of them but
this never works and it seems to ignore the exclude files we gave it.
To fix this the proper way is to mark all packages we only use locally
with !remote tags. This is a bit ugly but more correct. I also moved the
DecodeChanges() code around as it is called from the client so the
handles package which should only be remote doesn't really fit anyway.
