This adds a new command, 'podman network reload', to reload the
networks of existing containers, forcing recreation of firewall
rules after e.g. `firewall-cmd --reload` wipes them out.
Under the hood, this works by calling CNI to tear down the
existing network, then recreate it using identical settings. We
request that CNI preserve the old IP and MAC address in most
cases (where the container only had 1 IP/MAC), but there will be
some downtime inherent to the teardown/bring-up approach. The
architecture of CNI doesn't really make doing this without
downtime easy (or maybe even possible...).
At present, this only works for root Podman, and only locally.
I don't think there is much of a point to adding remote support
(this is very much a local debugging command), but I think adding
rootless support (to kill/recreate slirp4netns) could be
valuable.

We can't mount sysfs as rootless unless we manage the network
namespace. Problem: slirp4netns is now creating and managing a
network namespace separate from the OCI runtime, so we can't
mount sysfs in many circumstances. The `crun` OCI runtime will
automatically handle this by falling back to a bind mount, but
`runc` will not, so we didn't notice until RHEL gating tests ran
on the new branch.

* Add a new `pkg/copy` to centralize all container-copy related code.
* The new code is based on Buildah's `copier` package.
* The compat `/archive` endpoints use the new `copy` package.
* Update docs and an several new tests.
* Includes many fixes, most notably, the look-up of volumes and mounts.
Breaking changes:
* Podman is now expecting that container-destination paths exist.
Before, Podman created the paths if needed. Docker does not do
that and I believe Podman should not either as it's a recipe for
masking errors. These errors may be user induced (e.g., a path
typo), or internal typos (e.g., when the destination may be a
mistakenly unmounted volume). Let's keep the magic low for such
a security sensitive feature.

Our users are missing certain warning messages that would
make debugging issues with Podman easier.
For example if you do a podman build with a Containerfile
that contains the SHELL directive, the Derective is silently
ignored.
If you run with the log-level warn you get a warning message explainging
what happened.
$ podman build --no-cache -f /tmp/Containerfile1 /tmp/
STEP 1: FROM ubi8
STEP 2: SHELL ["/bin/bash", "-c"]

Docker defines an option of "default" which means to
use the default network. We should support this with
the same code path as --network="".
This is important for compatibility with the Docker API.

Previously, we always computed pause path from the Rootless
runtime directory. Problem: this does not match the behavior of
Libpod when the directory changes. Libpod will continue to use
the previous directory, cached in the database; Pause pidfiles
will swap to the new path. This is problematic when the directory
needs to exist to write the pidfile, and Libpod is what creates
the directory.
There are two potential solutions - allow the pause pidfile to
move and just make the directory when we want to write it, or use
the cached Libpod paths for a guaranteed location. This patch
does the second, because it seems safer - we will never miss a
previously-existing pidfile because the location is now
consistent.

Signed-off-by: Qi Wang <qiwan@redhat.com>
The network ID is not stored. It is just the sha256 hash from
the network name. There is a risk of a potential hash collision.
However it's very unlikely and even if we hit this it will
complain that more than network with this ID exists.
The main benefit is that the compat api can have proper
network ID support. Also this adds the support for
`podman network ls --format "{{.ID}}"` and `--filter id=<ID>`.
It also ensures that we can do network rm <ID> and network
inspect <ID>.
Since we use a hash this commit is backwards compatible even for
already existing networks.

Instead of being interpreted as an argument to the boolean flag,
the 'true' is being intepreted as the Podman command to be run -
so we're trying to run `podman true`, which does not exist. This
causes the cleanup command to fail when `--log-level=debug` is
set, so containers are not cleaned up or removed.
This problem is easily reproduced with any command combining the
`--rm`, `-d`, and `--log-level=debug` flags - the command will
execute and exit, but the container will not be removed.
Separate, but worth looking into later: the errors we get on
trying `podman true` with any flags are terrible - if you just
type `podman true` you get a quite sane "Unrecognized command"
error, but if you try `podman true --rm` you get an "unknown flag
--rm" error - which makes very little sense given the command
itself doesn't exist.

The It("podman wait to pause|unpause condition"... test is
flaking every so often when a messages is sent in the second
function to a channel. It is my believe that in between the time
the first function sends a message to the channel and before it closes
the channel the second errChan=make() has happened. This would mean that
the fist function closes the second errChan, and then when the second
function sends a message to the second errChan, it fails and blows up with
the error you are seeing.
By creating a different variable for the second channel, we eliminate the race.
