Delete needs to release names related to a container even if that
container isn't present in the db. However, slightly overzealous error
checking causes the transaction to get rolled back. Ignore the error
from Delete on the container itself, since it may not be present.

Currently, names are maintained by a separate system called "registrar".
This means there is no way to atomically snapshot the state of
containers and the names associated with them.
We can add this atomicity and simplify the code by storing name
associations in the memdb. This removes the need for pkg/registrar, and
makes snapshots a lot less expensive because they no longer need to copy
all the names. This change also avoids some problematic behavior from
pkg/registrar where it returns slices which may be modified later on.
Note that while this change makes the *snapshotting* atomic, it doesn't
yet do anything to make sure containers are named at the same time that
they are added to the database. We can do that by adding a transactional
interface, either as a followup, or as part of this PR.

Description:
1. start a container with restart=always.
`docker run -d --restart=always ubuntu sleep 3`
2. container init process exits.
3. use `docker pause <id>` to pause this container.
if the pause action is before cgroup data is removed and after the init process died.
`Pause` operation will success to write cgroup data, but actually do not freeze any process.
And then docker received pause event and stateExit event from
containerd, the docker state will be Running(paused), but the container
is free running.
Then we can not remove it, stop it , pause it and unpause it.

Doing a chown/chmod automatically can cause `EPERM` in some cases (e.g.
with an NFS mount). Currently Docker will always call chown+chmod on a
volume path unless `:nocopy` is passed in, but we don't need to make
these calls if the perms and ownership already match and potentially
avoid an uneccessary `EPERM`.

Commit abd72d4008dde7ee8249170d49eb4bc963c51e24 added
a "FIXME" comment to the container "State", mentioning
that a container cannot be both "Running" and "Paused".
This comment was incorrect, because containers on
Linux actually _must_ be running in order to be
paused.
This patch adds additional information both in a
comment, and in the API documentation to clarify
that these booleans are not mutually exclusive.

Component: engine
This patch consolidates the two WaitStop and WaitWithContext methods
on the container.State type. Now there is a single method, Wait, which
takes a context and a bool specifying whether to wait for not just a
container exit but also removal.
The behavior has been changed slightly so that a wait call during a
Created state will not return immediately but instead wait for the
container to be started and then exited.
The interface has been changed to no longer block, but instead returns
a channel on which the caller can receive a *StateStatus value which
indicates the ExitCode or an error if there was one (like a context
timeout or state transition error).
These changes have been propagated through the rest of the deamon to
preserve all other existing behavior.

This makes sure that multiple users of MountPoint pointer can
mount/unmount without affecting each other.
Before this PR, if you run a container (stay running), then do `docker
cp`, when the `docker cp` is done the MountPoint is mutated such that
when the container stops the volume driver will not get an Unmount
request. Effectively there would be two mounts with only one unmount.
