add a simple way to copy ulimit values from the host.
if --ulimit host is used then the current ulimits in place are copied

the compilation demands of having libpod in main is a burden for the
remote client compilations. to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.
this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

These are only used on OS X Docker, and ignored elsewhere - but
since they are ignored, they're guaranteed to be safe everywhere,
and people are using them.

We made changes earlier that empty storage options when setting
storage driver explicitly. Unfortunately, this breaks rootless
cleanup commands, as they lose the fuse-overlayfs mount program
path.
Fix this by passing along the storage options to the cleanup
process.
Also, fix --syslog, which was broken a while ago (probably when
we broke up main to add main_remote).

When we supercede low-priority mounts and volumes (image volumes,
and volumes sourced from --volumes-from) with higher-priority
ones (the --volume and --mount flags), we always replaced
lower-priority mounts of the same type (e.g. a user mount to
/tmp/test1 would supercede a volumes-from mount to the same
destination). However, we did not supercede the opposite type - a
named volume from image volumes at /tmp/test1 would be allowed to
remain and create a conflict, preventing container creation.
Solve this by destroying opposite types before merging (we can't
do it in the same loop, as then named volumes, which go second,
might trample changes made by mounts).

The on-failure restart option supports restarting only a given
number of times. To do this, we need one additional field in the
DB to track restart count (which conveniently fills a field in
Inspect we weren't populating), plus some plumbing logic.

This ensures that all tmpfs mounts added by the user, even with
the --mount flag, share a few common options (nosuid, noexec,
nodev), and options for tmpfs mounts are properly validated to
ensure they are correct.

As part of this, move bind mount option validity parsing and
modification (adding e.g. rbind on bind mounts that are missing

We were unconditionally resetting volume mount options for all
mount points (and by the looks of things, completely dropping
tmpfs mounts), which was causing runc to refuse to run containers
and all the tests to consequently fail.

Several changes made in the interface of pkg/spec make
interacting with it without a runtime difficult to impossible,
so move the existing limited testing from cmd/podman (which
mostly tested pkg/spec) into pkg/spec itself where we can call
individual functions that don't break things.

Unify handling for the --volume, --mount, --volumes-from, --tmpfs
and --init flags into a single file and set of functions. This
will greatly improve readability and maintainability.
Further, properly handle superceding and conflicting mounts. Our
current patchwork has serious issues when mounts conflict, or
when a mount from --volumes-from or an image volume should be
overwritten by a user volume or named volume.

Play kube was passing the pod, but CreateConfig was not. Unify it

The goal here is to keep only the configuration directly used to
build the container in CreateConfig, and scrub temporary state
and helpers that we need to generate. We'll keep those internally
in MakeContainerConfig.

Right now, there are two major API calls necessary to turn a
filled-in CreateConfig into the options and OCI spec necessary to
make a libpod Container. I'm intending on refactoring both of
these extensively to unify a few things, so make a common
frontend to both that will prevent API changes from leaking out
of the package.

The --read-only-tmpfs option caused podman to mount tmpfs on /run, /tmp, /var/tmp
if the container is running int read-only mode.
The default is true, so you would need to execute a command like
--read-only --read-only-tmpfs=false to turn off this behaviour.

We accidentally patched this out trying to enable ns:/path/to/ns
This should restore the ability to configure nondefault CNI
networks with Podman, by ensuring that they request creation of a
network namespace.
Completely remove the WithNetNS() call when we do use an explicit
namespace from a path. We use that call to indicate that a netns
is going to be created - there should not be any question about
whether it actually does.

We have a very high performance JSON library that doesn't need to
perform code generation. Let's use it instead of our questionably

Most changes because some functions can now return errors.
Also converts cmd/podman to use jsoniter, instead of pkg/json,
for increased performance.
