use a pause process to keep the user and mount namespace alive.
The pause process is created immediately on reload, and all successive
Podman processes will refer to it for joining the user&mount
namespace.
This solves all the race conditions we had on joining the correct
namespaces using the conmon processes.
As a fallback if the join fails for any reason (e.g. the pause process
was killed), then we try to join the running containers as we were
doing before.

In cases where the remote client culls options to a command, we need to
be sure that the lookup for that flag does not result in a nil pointer.
To do so, we add a Remote attribute to the podman struct and then cli
helper funcs are now aware they are remote.

in the few places where we care about skipping the storage
initialization, we can simply use the process effective UID, instead
of relying on a global boolean flag.

We have a very high performance JSON library that doesn't need to
perform code generation. Let's use it instead of our questionably
performant, reflection-dependent deep copy library.
Most changes because some functions can now return errors.
Also converts cmd/podman to use jsoniter, instead of pkg/json,
for increased performance.

Inspired by #2684, I wrote a CI test to look for other such
instances in which a command is invoked without a required
argument. 'podman umount' seems to be the only one, and
solution is simple: checkAllAndLatest() already does the
check for us.
Resolve a few other problems uncovered by testing:
podman mount: indicate that CONTAINER arg is optional
podman pod stats: ditto
podman generate kube: remove check for -l (latest) flag,
it isn't actually implemented.

Conceptually simple: include, where applicable, a brief
description of command-line options for each subcommand.

in the case of the remote-client, it was decided to hide the latest
flag to avoid confusion for end-users on what the "last" container,
volume, or pod are.

Subcommands should not be showing the global flags. This causes the important
information to scroll off the screen.
Also fixed a typo on runCommmand (Too many 'm's)

In the previous CLI, we had an accurate depiction of commands
available for the remote client and those available for the
local client.

We intend to migrate to the cobra cli from urfave/cli because the
project is more well maintained. There are also some technical reasons
as well which extend into our remote client work.

We have no consistancy in out option usages and descritions
on whether or not the first letter should be capatalized.
This patch forces them all to be capatilized.

when using a driver different than vfs, the mount is probably in a
different mount namespace thus not accessible from the host. Avoid
the confusion by not allowing mount when a different driver is used.

Don't print potentially verbose help messages in case of usage errors,
but print only the usage error followed by a pointer to the command's
help. This aligns with Docker.
```
$ podman run -h
flag needs an argument: -h
See 'podman run --help'.

Addresses a regression in `podman mount` due to our mount changes
to allow concurrency by letting c/storage handle mounting and
unmounting.
Combine Mounted() and Mountpoint() into one function and query
c/storage directly to ensure we get accurate information.

implement varlink image functions for working with libpod with the exception of a
couple due to incompletions on the libpod side of things (build).
also, created a first pass at a libpodpy package which will stand as a client to
working with libpod's varlink methods using python.
