Because /etc/hosts is shared for all containers with a shared network
namespace you should not be able to add hosts from a joined container.
Only the primary netns container can set the hosts.

When we connect or disconnect from a network we also have to update
/etc/hosts to ensure we only have valid entries in there.
This also fixes problems with docker-compose since this makes use of
network connect/disconnect.

When we lookup the hostname for a given container we have to check if
the container is joined to another utsns and use this hostname then
instead.
This fixes a problem where the `hostname` command would use the correct
name but /etc/hostname would contain a different name.

Use the new logic from c/common to create the hosts file. This will help
to better allign the hosts files between buildah and podman.
Also this fixes several bugs:
- remove host entries when container is stopped and has a netNsCtr
- add entries for containers in a pod
- do not duplicate entries in the hosts file
- use the correct slirp ip when an userns is used
Features:
- configure host.containers.internal entry in containers.conf
- configure base hosts file in containers.conf
Fixes #12003
Fixes #13224

From a security point of view, it would be nice to be able to map a
rootless usernamespace that does not use your own UID within the
container.
This would add protection against a hostile process escapping the
container and reading content in your homedir.

Following commit ensures that csv escaping is supported while using
inline `--mount=type=......` flag with `podman run` by using
`encoding/csv` to parse options instead of performing a `split.String(`
by `comma`.

system tests: add assert(), and start using it

Problem: the system test 'is()' checker was poorly thought out.
For example, there is no way to check for inequality or for
absence of a substring.
Solution, step 1: introduce new assert(), copied almost verbatim
from buildah, where it has been successful in addressing the
gaps in is().
The logical next step is to search the tests for 'die' and
for 'run', looking for negative assertions which we can
replace with assert(). There were a lot, and in the process
I found a number of ugly bugs in the tests themselves. I've
taken the liberty of fixing these.
Important note: at this time we have both assert() and is().
Replacing all instances of is() would be impossible to review.

Workaround criu re-linking output in system test

When run on an F36 host using netavark/aardvark-dns, for whatever
underlying reason most checkpoint/restore tests are emitting an error
similar to:
`criu: Symbol `__rseq_offset' has different size in shared object,
consider re-linking`
This extraneous output is causing the basic checkpoint system test to
fail. Since, all other testing of checkpoint/restore feature is
passing (also with the extraneous message) loosen the system test
sensitivity to match.

When this option was added to the e2e tests, there was no CI Automation
support for running remote tests w/ netavark. When added, many
e2e test errors/failures are generated due to this option not being
valid for the remote client. Fix this in the tests by conditionally
adding the option if the test is running the remote client.

On F36 / podman 4, at the time of this commit there is no
`/etc/containers/storage.conf` installed by default. Since the
test volume-mounts this file into the container, it was failing. Fix
this by using a conditional volume-mount based on the file existing (or
not).

The patch introduces the following test cases:
1. An attempt to checkpoint a container that does not exist should fail.
2. Checkpoint of a running container with --create-image should create a
checkpoint image.
3. A single checkpoint image can be used to restore multiple containers,
each with a different name.
4. Restoring multiple containers from checkpoint images with a single
restore command.

Use of `$DEBUG` is highly likely to clash. Fortunately this one is in
a very specific/special context, so a rename fix should be perfectly
adequate.

benchmarking Podman: proof of concept

Add a proof of concept for benchmarking Podman. The benchmarks are
implemented by means of the end-to-end test suite but hidden behind
a `benchmarks` build tag. Running `make localbenchmarks` will run
`test/e2e` with the specific build tag and set ginkgo's "focus" to
the specific "Podman Benchmark Suite" to only run this spec and skip
all others.
ginkgo will print a report before terminating listing the CPU and memory
stats for each benchmark. New benchmarks can easily be added via the
`newBenchmark` function that also supports adding an `init()` function
to each benchmark which allows for performing certain setups for the
specific benchmark. For instance, benchmarking `podman start` requires
creating a container beforehand.
Podman may be called more than once in the main function of a benchmark
but note that the displayed memory consumption is then a sum of all
Podman invocations. The memory consumption is collected via
`/usr/bin/time`.
A benchmark's report is split into CPU and memory as displayed below:
```
[CPU] podman images:
Fastest Time: 0.146s
Slowest Time: 0.187s
Average Time: 0.180s ± 0.015s
[MEM] podman images:
Smallest: 41892.0KB
Largest: 42792.0KB
Average: 42380.7KB ± 286.4KB
```
Note that the benchmarks are not wired into the CI yet. They are meant
as a proof of concept. More benchmarks and the plumbing into CI will
happen in a later change.

--tail=1 is not working f you restart a container with journald logging.
We see the exit status and then call into the logging a second time
causing all of the logs to print.
Removing the tail log on exited seems to fix the problem.
