Currently, daemonbuilder package (part of daemon) implemented the
builder backend. However, it was a very thin wrapper around daemon
methods and caused an implementation dependency for api/server build
endpoint. api/server buildrouter should only know about the backend
implementing the /build API endpoint.
Removing daemonbuilder involved moving build specific methods to
respective files in the daemon, where they fit naturally.

The restart container has already prepared the mountpoint, there is
no need to do that again. This can speed up the daemon start if
the restart container has a volume and the volume driver is not
available.

daemon cache was getting the whole image map and then iterating through
it to find children. This information is already stored in the image
store.
Prior to this change building the docker repo with a full cache took 30
seconds.
After it takes between 15 seconds or less (As low as 9 seconds).
This is an improvement on docker 1.9.1 which hovered around 17 seconds.

During daemon startup, all containers are registered before any are
started.
During container registration it was calling out to initialize volumes.
If the volume uses a plugin that is running in a container, this will
cause the restart of that container to fail since the plugin is not yet
running.
This also slowed down daemon startup since volume initialization was
happening sequentially, which can be slow (and is flat out slow since
initialization would fail but take 8 seconds for each volume to do it).
This fix holds off on volume initialization until after containers are
restarted and does the initialization in parallel.
The containers that are restarted will have thier volumes initialized
because they are being started. If any of these containers are using a
plugin they will just keep retrying to reach the plugin (up to the
timeout, which is 8seconds) until the container with the plugin is up
and running.

Read configuration after flags making this the priority:
1- Apply configuration from file.
2- Apply configuration from flags.
Reload configuration when a signal is received, USR2 in Linux:
- Reload router if the debug configuration changes.
- Reload daemon labels.
- Reload cluster discovery.

Before #16032, once links were setup
in the sqlite db, hostConfig.Links was cleared out.
This means that we need to migrate data back out of the sqlite db and
put it back into hostConfig.Links so that links specified on older
daemons can be used.

Don't rely on sqlite db for name registration and linking.
Instead register names and links when the daemon starts to an in-memory
store.

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.

Merge was used by builder and daemon. With this commit, the builder
call has been inlined and the function moved to the daemon package,
which is the only other caller.

When a container is created it is registered before the mount is created. This can lead to mount does not exist errors when inspecting between create and mount.

RWLayer will now have more operations and be protected through a referenced type rather than always looked up by string in the layer store.
Separates creation of RWLayer (write capture layer) from mounting of the layer.
This allows mount labels to be applied after creation and allowing RWLayer objects to have the same lifespan as a container without performance regressions from requiring mount.
