requested but not installed we should error.

When podman gets an error it prints out "Error: " before
printing the error string. If the error message starts with
error, we end up with
Error: error ...
This PR Removes all of these stutters.
logrus.Error() also prints out that this is an error, so no need for the
error stutter.

When a user has a http proxy configured the VM will use it. However
since gvproxy can only be reached internally from within the VM the port
forwarding HTTP API call should not be redirected to the proxy.

Issue #10927 reports `container create failed (no logs from conmon): EOF`
errors. Since we do not know the root cause it would be helpful to try
to get as much info as possible out of the error.
(buffer).ReadBytes() will return the bytes read even when an error
occurs. So when we get an EOF we could still have some valuable
information in the buffer. Lets try to unmarshal them and if this fails
we add the bytes to the error message.
This does not fix the issue but it might help us getting a better error.

Every exec session run attached will, on exit, do two things: it
will signal the associated `podman exec` that it is finished (to
allow Podman to collect the exit code and exit), and spawn a
cleanup process to clean up the exec session (in case the `podman
exec` process died, we still need to clean up). If an exec
session is created that exits almost instantly, but generates a
large amount of output (e.g. prints thousands of lines), the
cleanup process can potentially execute before `podman exec` has
a chance to read the exit code, resulting in errors. Handle this
by detecting if the cleanup process has already removed the exec
session before handling the error from reading the exec exit
code.
[NO NEW TESTS NEEDED] I have no idea how to test this in CI.

We can just calculate the cpu percent for the time the container is
running. There is no need to use datapoints.
Signed-off-by: Paul Holzinger <pholzing@redhat.com>
When you run podman stats, the first interval always shows the wrong cpu
usage. To calculate cpu percentage we get the cpu time from the cgroup
and compare this against the system time between two stats. Since the
first time we do not have a previous stats an empty struct is used
instead. Thus we do not use the actual running time of the container but
the current unix timestamp (time since Jan 1 1970).
To fix this we make sure that the previous stats time is set to the
container start time, when it is empty.
[NO NEW TESTS NEEDED] No idea how I could create a test which would have
a predictable cpu usage.
See the linked bugzilla for a reproducer.

Inside the podman machine vm we always remove the hostip from the port
mapping because this should only be used on the actual host. Otherwise
you run into issues when we would bind 127.0.0.1 or try to bind a
host address that is not available in the VM.
This was already done for cni/netavark ports and slirp4netns but not for
the port bindings inside libpod which are only used as root.

When enable_ipv6=true is set for slirp4netns (default since podman v4),
we will try to set the accept sysctl. This sysctl will not exist on
systems that have ipv6 disabled. In this case we should not error and
just ignore the extra ipv6 setup.
Also the current logic to wait for the slirp4 setup was kinda broken, it
did not actually wait until the sysctl was set before starting slirp.
This should now be fixed by using two `sync.WaitGroup`s.

While resolving `workdir` we mostly create a `workdir` when `stat`
fails with `ENOENT` or `ErrNotExist` however following cases are not
true when user explicitly specifies a `workdir` while `running` using
`--workdir` which tells `podman` to only use workdir if its exists on
the container. Following configuration is implicity set with other
`run` mechanism like `podman play kube`
Problem with explicit `--workdir` or similar implicit config in `podman play
kube` is that currently podman ignores the fact that workdir can also be
a `symlink` and actual `link` could be valid.
Hence following commit ensures that in such scenarios when a `workdir`
is not found and we cannot create a `workdir` podman must perform a
check to ensure that if `workdir` is a `symlink` and `link` is resolved
successfully and resolved link is present on the container then we
return as it is.
Docker performs a similar behviour.
