This commit adds a function which can be used to ensure all contents of
a directory can be accessed.
This function doesn't follow symlinks to check if they're pointing to
files which exist. Such symlinks can be useful later.

This commit refactors TruncIndex to make it possible to add container
ids to the TruncIndex without updating the Suffixarray.
This is useful during the Docker daemon's startup when we don't want to
update the Suffixarray for every container we add.
Add continues to function like before.

Fixes#5166
Current graph.restore is essentially O(n^2 log n) due to how
suffixarray creation works.
Rather than create/append/create new this supports creation from a seed
array of ids.
Functional testing shows this eliminates the hang on Creating image
graph reported on list.

In order to handle special configuration for different drivers we
make the Config field a map to string array. This lets
us use it for lxc, by using the "lxc" key for those, and we can
later extend it easily for other backend-specific options.

This removes the incomplete symlink handling from engine.go and it adds
it one place in docker.go.
It also enables handling symlinks for TMPDIR.

This stops docker from accepting tcp:// as a valid bind address.

This adds the ability to socket activate docker by passing in
`-H fd://*` along with examples systemd configuration files.
The fastest way to test this is to run:
```
/usr/lib/systemd/systemd-activate -l 127.0.0.1:2001 /usr/bin/docker -d -H 'fd://*'
docker -H tcp://127.0.0.1:2001 ps
```

The idx.index array is overwritten when a new value is inserted to the index.
When two containers are created concurrently, their ids are inserted to the
index and one can overwrite the other leaving one of ids missing from the
index. Adding a RWMutex lock around read/write operations fixes this.

To avoid unexpected results since docker was using http.
For instance, my broadband doesn't return not found when it's down but
a html page saying that the internet is down. Docker was showing that
html instead of ignoring it.

Use mountinfo rather than for cgroups parsing.
Make helper method private and change name.
Makes method naming more explicit rather than GetThisCgroup.
Use upstream term subsystem rather than cgroupType.
Only necessary if distro policy dictates that the path deviate from the paths already listed in utils/utils.go - please refrain from using it otherwise.
