this improves the error message if a user tries to
create a volume with a single-character name:
Before this change:
docker volume create --name a
Error response from daemon: create a: "a" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed
After this change:
docker volume create --name a
Error response from daemon: create a: volume name is too short, names should be at least two alphanumeric characters

On daemon restart the local volume driver will read options that it
persisted to disk, however it was reading an incorrect path, causing
volume options to be silently ignored after a daemon restart.

This generates an ID string for calls to Mount/Unmount, allowing drivers
to differentiate between two callers of `Mount` and `Unmount`.

Allows users to submit options similar to the `mount` command when
creating a volume with the `local` volume driver.
For example:
```go
$ docker volume create -d local --opt type=nfs --opt device=myNfsServer:/data --opt o=noatime,nosuid
```

Makes `docker volume ls` and `docker volume inspect` ask the volume
drivers rather than only using what is cached locally.
Previously in order to use a volume from an external driver, one would
either have to use `docker volume create` or have a container that is
already using that volume for it to be visible to the other volume
API's.
For keeping uniqueness of volume names in the daemon, names are bound to
a driver on a first come first serve basis. If two drivers have a volume
with the same name, the first one is chosen, and a warning is logged
about the second one.
Adds 2 new methods to the plugin API, `List` and `Get`.
If a plugin does not implement these endpoints, a user will not be able
to find the specified volumes as well requests go through the drivers.

Delegate validation tasks to the volume drivers. It's up to them
to decide whether a name is valid or not.
Restrict volume names for the local driver to prevent creating
mount points outside docker's volumes directory.

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.

Underlying volume data may have been removed by some other tool.
Ignore and remove the reference in this case.
