Continuation of: #11660, working on issue #11626.
Wrapped portmapper global state into a struct. Now portallocator and
portmapper have no global state (except configuration, and a default
instance).
Unfortunately, removing the global default instances will break
```api/server/server.go:1539```, and ```daemon/daemon.go:832```, which
both call the global portallocator directly. Fixing that would be a much
bigger change, so for now, have postponed that.

When the deamon starts up with log level set to INFO it will show something
like this:
```
INFO[0000] Loading containers: start.
................................................................
INFO[0000] Loading containers: done.
```
where the dots represent containers in the system.
When you run with log level set to "error" it will still show the dots
w/o the "Loading..." lines before and after which looks really odd.
This PR will fix it so that the dots are only shown IFF the "Loading..."
lines are also shown

Currently the daemon will not stop on error because the serve API job is
blocking the channel wait for daemon init. A better way is to run the
blocking serve API job as a goroutine and make sure that error
notification gets back to the main daemon thread (using the already
existing channel) so that clean shutdown can occur on error.

Cgroup resources are host dependent, they should be in hostConfig.
For backward compatibility, we just copy it to hostConfig, and leave it in
Config for now, so there is no regressions, but the right way to use this
throught json is to put it in HostConfig, like:
{
"Hostname": "",
...
"HostConfig": {
"CpuShares": 512,
"Memory": 314572800,
...
}
}
As we will add CpusetMems, CpusetCpus is definitely a better name, but some
users are already using Cpuset in their http APIs, we also make it compatible.
The main idea is keep using Cpuset in Config Struct, and make it has the same
value as CpusetCpus, but not always, some scenarios:
- Users use --cpuset in docker command, it can setup cpuset.cpus and can
get Cpuset field from docker inspect or other http API which will get
config info.
- Users use --cpuset-cpus in docker command, ditto.
- Users use Cpuset field in their http APIs, ditto.
- Users use CpusetCpus field in their http APIs, they won't get Cpuset field
in Config info, because by then, they should already know what happens
to Cpuset.

This change adds daemon's system time as RFC3339Nano to the `/info` endpoint
and shows in a more readable format (UnixDate) in `docker -D info` output.
I will be using this to fix the clock skew between the remote test host and
the CI machines running `docker events`-related tests as they're using `--since`
and `--until` and the timestamps are not matching when daemon is not on the
same machine.

Previously on error either from the daemon or from the api it is just
exiting with exit status 1 but not performing a shutdown.
This can produce insconsistent state depending on where the error came
from.
This makes sure that before we exit on error that the engine gets fully
shutdown.

daemon/volumes.go
This SetFileCon call made no sense, it was changing the labels of any
directory mounted into the containers SELinux label. If it came from me,
then I apologize since it is a huge bug.
The Volumes Mount code should optionally do this, but it should not always
happen, and should never happen on a --privileged container.
The change to
daemon/graphdriver/vfs/driver.go, is a simplification since this it not
a relabel, it is only a setting of the shared label for docker volumes.

Create container job could fail because a container specified with
`--volumes-from` does not exist. This error is not propagated to client
though. Instead it's recognized by higher levels as "image not found".
Client then tries to pull the image and launch the container again.
This patch changes the lower level error message so that it's not
recognized as "image not found" and thus it's propagated to client.

Currently when containers are linked the alias name (e.g. from `--link
name:alias`) is added to the parent container's `/etc/hosts` with a
reference to the IP of the linked container. Some software requires
using the official hostname or node name in operations that need to
match on those values, and it is therefore helpful if the parent
container can refer to the child/link using those same values and still
access the same IP.

Fixes#9981
Allows a volume which was created by docker (ie, in
/var/lib/docker/vfs/dir) to be used as a Bind argument via the container
start API and overwrite an existing volume.
For example:
```bash
docker create -v /foo --name one
docker create -v /foo --name two
```
This allows the volume from `one` to be passed into the container start
API as a bind to `two`, and it will overwrite it.
This was possible before 7107898d5c

I don't think that it was very useful feature in current implementation,
but when you have a lot of links - your daemon became unusable because
on first call of /containers global graphdb lock will be acquired and it
can take a lot of time: 30m for 15 containers linked to each other.
Links names can be seen with `--no-trunc`, but I think it's useless :)

Currently docker build is not passing HostConfig to daemon.Create.
this patch creates the default HostConfig and passes it to daemon.Create.
This will cause the SELinux labeling to turn on for docker build. Basically
it causes a SecurtyOpt field to be created. In the future this might also
allow us to use seccomp and UserNamespace with docker build.
