This adds the 'system service' command to the build on FreeBSD and
suppresses the call to servicereaper.Start which is only needed to
support slirp4netns on Linux. A stub for compat.StatsContainer is also
added - stats are still supported via the libpod.StatsContainer API
call.

To debug a deadlock, we really want to know what lock is actually
locked, so we can figure out what is using that lock. This PR
adds support for this, using trylock to check if every lock on
the system is free or in use. Will really need to be run a few
times in quick succession to verify that it's not a transient
lock and it's actually stuck, but that's not really a big deal.

This is a general debug command that identifies any lock
conflicts that could lead to a deadlock. It's only intended for
Libpod developers (while it does tell you if you need to run
`podman system renumber`, you should never have to do that
anyways, and the next commit will include a lot more technical
info in the output that no one except a Libpod dev will want).
Hence, hidden command, and only implemented for the local driver
(recommend just running it by SSHing into a `podman machine` VM
in the unlikely case it's needed by remote Podman).
These conflicts should normally never happen, but having a
command like this is useful for debugging deadlock conditions
when they do occur.

system reset it says it will delete containers, images, networks, etc...
However it will also delete the graphRoot and runRoot directories.
Normally this is not an issue, however in same cases these directories
were set to the users home directory or some other important system
directory.
As first step simply show the directories that are configured and thus
will be deleted by reset. As future step we could implement some
safeguard will will not delete some known important directories however
I tried to keep it simple for now.

The current code modifies a global variable which works but is bad
design since it could be uses elsewhere. Since we just exit after the df
command this is not an issue right now but it could become one in the
future.
A better fix is to implement a custom `MarshalJSON()` method on the

Use `Default()` instead of re-loading containers.conf.
Also rework how the containers.conf objects are handled for parsing the
CLI. Previously, we were conflating "loading the defaults" with
"storing values from the CLI" with "libpod may further change fields"
which ultimately led to various bugs and test failues.
To address the issue, separate the defaults from the values from the CLI
and properly name the fields to make the semantics less ambiguous.

Fix two bugs in `system df`:
1. The total size was calculated incorrectly as it was creating the sum
of all image sizes but did not consider that a) the same image may
be listed more than once (i.e., for each repo-tag pair), and that
b) images share layers.
The total size is now calculated directly in `libimage` by taking
multi-layer use into account.
2. The reclaimable size was calculated incorrectly. This number
indicates which data we can actually remove which means the total
size minus what containers use (i.e., the "unique" size of the image
in use by containers).
NOTE: The c/storage version is pinned back to the previous commit as it
is buggy. c/common already requires the buggy version, so use a
`replace` to force/pin.

implement new ssh interface into podman
this completely redesigns the entire functionality of podman image scp,
podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh
have been moved to common as have native ssh/scp execs and the new usage of the sftp package.
this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default.
Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the
ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production.
The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used.
podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls.
My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.

add support for podman-remote image scp as well as direct access via the API. This entailed
a full rework of the layering of image scp functions as well as the usual API plugging and type creation
also, implemented podman image scp tagging. which makes the syntax much more readable and allows users t tag the new image
they are loading to the local/remote machine:
allow users to pass a "new name" for the image they are transferring
`podman tag` as implemented creates a new image im `image list` when tagging, so this does the same
meaning that when transferring images with tags, podman on the remote machine/user will load two images
ex: `podman image scp computer1::alpine computer2::foobar` creates alpine:latest and localhost/foobar on the remote host
implementing tags means removal of the flexible syntax. In the currently released podman image scp, the user can either specify
`podman image scp source::img dest::` or `podman image scp dest:: source::img`. However, with tags this task becomes really hard to check
which is the image (src) and which is the new tag (dst). Removal of that streamlines the arg parsing process
