`Mounts` allows users to specify in a much safer way the volumes they
want to use in the container.
This replaces `Binds` and `Volumes`, which both still exist, but
`Mounts` and `Binds`/`Volumes` are exclussive.
The CLI will continue to use `Binds` and `Volumes` due to concerns with
parsing the volume specs on the client side and cross-platform support
(for now).
The new API follows exactly the services mount API.
Example usage of `Mounts`:
```
$ curl -XPOST localhost:2375/containers/create -d '{
"Image": "alpine:latest",
"HostConfig": {
"Mounts": [{
"Type": "Volume",
"Target": "/foo"
},{
"Type": "bind",
"Source": "/var/run/docker.sock",
"Target": "/var/run/docker.sock",
},{
"Type": "volume",
"Name": "important_data",
"Target": "/var/data",
"ReadOnly": true,
"VolumeOptions": {
"DriverConfig": {
Name: "awesomeStorage",
Options: {"size": "10m"},
Labels: {"some":"label"}
}
}]
}
}'
```
There are currently 2 types of mounts:
- **bind**: Paths on the host that get mounted into the
container. Paths must exist prior to creating the container.
- **volume**: Volumes that persist after the
container is removed.
Not all fields are available in each type, and validation is done to
ensure these fields aren't mixed up between types.

This makes sure that:
1. Already existing directories are left untouched
2. Newly created directories are chowned to the correct root UID/GID in case of user namespaces
3. All parent directories still get created with host root UID/GID

In order to be consistent on creation of volumes for bind mounts
we need to create the source directory if it does not exist and the
user specified he wants it relabeled.
Can not do this lower down the stack, since we are not passing in the
mode fields.

Currently on daemon start volumes are "created" which involves invoking
a volume driver if needed. If this process fails the mount is left in a
bad state in which there is no source or Volume set. This now becomes
an unrecoverable state in which that container can not be started. The
only way to fix is to restart the daemon and hopefully you don't get
another error on startup.
This change moves "createVolume" to be done at container start. If the
start fails it leaves it in the state in which you can try another
start. If the second start can contact the volume driver everything
will recover fine.

not have the same rules for Gid, so stat package has calls UID() and

Adds support for the daemon to handle user namespace maps as a
per-daemon setting.
Support for handling uid/gid mapping is added to the builder,
archive/unarchive packages and functions, all graphdrivers (except
Windows), and the test suite is updated to handle user namespace daemon
rootgraph changes.

Although having a request ID available throughout the codebase is very
valuable, the impact of requiring a Context as an argument to every
function in the codepath of an API request, is too significant and was
not properly understood at the time of the review.
Furthermore, mixing API-layer code with non-API-layer code makes the
latter usable only by API-layer code (one that has a notion of Context).
This reverts commit de4164043546d2b9ee3bf323dbc41f4979c84480, reversing

This PR adds a "request ID" to each event generated, the 'docker events'
stream now looks like this:
```
2015-09-10T15:02:50.000000000-07:00 [reqid: c01e3534ddca] de7c5d4ca927253cf4e978ee9c4545161e406e9b5a14617efb52c658b249174a: (from ubuntu) create
```
Note the `[reqID: c01e3534ddca]` part, that's new.
Each HTTP request will generate its own unique ID. So, if you do a
`docker build` you'll see a series of events all with the same reqID.
This allow for log processing tools to determine which events are all related
to the same http request.
I didn't propigate the context to all possible funcs in the daemon,
I decided to just do the ones that needed it in order to get the reqID
into the events. I'd like to have people review this direction first, and
if we're ok with it then I'll make sure we're consistent about when
we pass around the context - IOW, make sure that all funcs at the same level
have a context passed in even if they don't call the log funcs - this will
ensure we're consistent w/o passing it around for all calls unnecessarily.

When using a named volume without --volume-driver, the driver was
hardcoded to "local".
Even when the volume was already created by some other driver (and
visible in `docker volume ls`), the container would store in it's own
config that it was the `local` driver.
The external driver would work perfecly fine until the daemon is
restarted, at which point the `local` driver was assumed because that is
as it was set in the container config.
Set the bind driver to the driver returned by createVolume.

1. rename it from ValidateMountMode to ValidMountMode
Because it's a function simply check mount mode is valid or not.
2. remove the rw check return value
It's not supposed to be combined into this function, and we already
have a function for that check.
