Add a new flag to set the start timeout for a generated systemd unit.
To make naming consistent, add a new --stop-timeout flag as well and let
the previous --time map to it.

There are at least two runtimes that support checkpoint and restore:
runc and crun. Although the checkpoints created by these are almost
compatible, it is not (yet) possible to restore a checkpoint created
with one runtime with the other runtime. To make checkpoint/restore
usage more comfortable this adds code to look into the checkpoint
archive during restore and to set the runtime to the one used during
checkpointing.
This also adds a check, if the user explicitly sets a runtime during
restore, that the runtime is also the same as used during checkpointing.
If a different runtime is selected than the one used during
checkpointing the restore will fail early.
If runc and crun will create compatible checkpoints in the future the
check can be changed to treat crun and runc as compatible
checkpoint/restore runtimes.

Podman adds a few environment variables by default, and
currently there is no way to get rid of them from your container.
This option will allow you to specify which defaults you don't
want.
--unsetenv-all will remove all default environment variables.
Default environment variables can come from podman builtin,
containers.conf or from the container image.

This adds the parameter '--print-stats' to 'podman container restore'.
With '--print-stats' Podman will measure how long Podman itself, the OCI
runtime and CRIU requires to restore a checkpoint and print out these
information. CRIU already creates process restore statistics which are
just read in addition to the added measurements. In contrast to just
printing out the ID of the restored container, Podman will now print
out JSON:
# podman container restore --latest --print-stats
{
"podman_restore_duration": 305871,
"container_statistics": [
{
"Id": "47b02e1d474b5d5fe917825e91ac653efa757c91e5a81a368d771a78f6b5ed20",
"runtime_restore_duration": 140614,
"criu_statistics": {
"forking_time": 5,
"restore_time": 67672,
"pages_restored": 14
}
}
]
}
The output contains 'podman_restore_duration' which contains the
number of microseconds Podman required to restore the checkpoint. The
output also includes 'runtime_restore_duration' which is the time
the runtime needed to restore that specific container. Each container
also includes 'criu_statistics' which displays the timing information
collected by CRIU.

The OCICNI port format has one big problem: It does not support ranges.
So if a users forwards a range of 1k ports with podman run -p 1001-2000
we have to store each of the thousand ports individually as array element.
This bloats the db and makes the JSON encoding and decoding much slower.
In many places we already use a better port struct type which supports
ranges, e.g. `pkg/specgen` or the new network interface.
Because of this we have to do many runtime conversions between the two
port formats. If everything uses the new format we can skip the runtime
conversions.
This commit adds logic to replace all occurrences of the old format
with the new one. The database will automatically migrate the ports
to new format when the container config is read for the first time
after the update.
The `ParsePortMapping` function is `pkg/specgen/generate` has been
reworked to better work with the new format. The new logic is able
to deduplicate the given ports. This is necessary the ensure we
store them efficiently in the DB. The new code should also be more
performant than the old one.
To prove that the code is fast enough I added go benchmarks. Parsing
1 million ports took less than 0.5 seconds on my laptop.
Benchmark normalize PortMappings in specgen:
Please note that the 1 million ports are actually 20x 50k ranges
because we cannot have bigger ranges than 65535 ports.

Since we want to use the rootless cni ns also for netavark we should
pick a more generic name. The name is now "rootless network namespace"
or short "rootless netns".
The rename might cause some issues after the update but when the
all containers are restarted or the host is rebooted it should work
correctly.
