Currently if you attempt to create a kube.yaml file off of a non running
container where the container runs as a specific User, the creation
fails because the storage container is not mounted. Podman is supposed to
read the /etc/passwd entry inside of the container but since the
container is not mounted, the c.State.Mountpoint == "". Podman
incorrectly attempts to read /etc/passwd on the host, and fails if the
specified user is not in the hosts /etc/passwd.
This PR mounts the storage container, if it was not mounted so the read
succeeds.

The --trace has helped in early stages analyze Podman code. However,
it's contributing to dependency and binary bloat. The standard go
tooling can also help in profiling, so let's turn `--trace` into a NOP.

This patch will allow users to pass in the time 0.
Currently the timeout will take 10 seconds if user passes
in the 0 flag.

Unlocking an already unlocked lock is a panic. As such, we have
to make sure that the deferred c.lock.Unlock() in
c.StopWithTimeout() always runs on a locked container. There was
a case in c.stop() where we could return an error after we unlock
the container to stop it, but before we re-lock it - thus
allowing for a double-unlock to occur. Fix the error return to
not happen until after the lock has been re-acquired.

The NanoCpus field in HostConfig was not wired up. It conflicts
with CPU period and quota (it hard-codes period to a specific
value and then sets the user-specified value as Quota).

Traditionally, the path resolution for containers has been resolved on
the *host*; relative to the container's mount point or relative to
specified bind mounts or volumes.
While this works nicely for non-running containers, it poses a problem
for running ones. In that case, certain kinds of mounts (e.g., tmpfs)
will not resolve correctly. A tmpfs is held in memory and hence cannot
be resolved relatively to the container's mount point. A copy operation
will succeed but the data will not show up inside the container.
To support these kinds of mounts, we need to join the *running*
container's mount namespace (and PID namespace) when copying.
Note that this change implies moving the copy and stat logic into
`libpod` since we need to keep the container locked to avoid race
conditions. The immediate benefit is that all logic is now inside
`libpod`; the code isn't scattered anymore.
Further note that Docker does not support copying to tmpfs mounts.
Tests have been extended to cover *both* path resolutions for running
and created containers. New tests have been added to exercise the
tmpfs-mount case.
For the record: Some tests could be improved by using `start -a` instead
of a start-exec sequence. Unfortunately, `start -a` is flaky in the CI
which forced me to use the more expensive start-exec option.
