The test-file had a duplicate definition for ErrNotImplemented, which
caused an error in this package, and was not used otherwise, so we can
remove this file.

There is no meaningful distinction between driverapi.Registerer and
drvregistry.DriverNotifyFunc. They are both used to register a network
driver with an interested party. They have the same function signature.
The only difference is that the latter could be satisfied by an
anonymous closure. However, in practice the only implementation of
drvregistry.DriverNotifyFunc is the
(*libnetwork.Controller).RegisterDriver method. This same method also
makes the libnetwork.Controller type satisfy the Registerer interface,
therefore the DriverNotifyFunc type is redundant. Change
drvregistry.Networks to notify a Registerer and drop the
DriverNotifyFunc type.

This method is not part of any interface, and identical to Endpoint.Iface,
but one returns an Interface-type (driverapi.InterfaceInfo) and the other
returns a concrete type (EndpointInterface).
Interface-matching should generally happen on the receiver side, and this
function was only used in a single location, and passed as argument to
Driver.CreateEndpoint, which already matches the interface by accepting
a driverapi.InterfaceInfo.

Copying relevant documentation from the EndpointInfo interface. We should
remove this interface, and the related Info() function, but it's currently
acting as a "gate" to prevent accessing the Endpoint's accessors without
making sure it's fully hydrated.

InterfaceOptions() returned an IfaceOptionSetter interface, which contained
"methods" that returned functional options. Such a construct could have made
sense if the functional options returned would (e.g.) be pre-propagated with
information from the Sandbox (network namespace), but none of that was the case.
There was only one implementation of IfaceOptionSetter (networkNamespace),
which happened to be the same as the only implementation of Sandbox, so remove
the interface as well, to help networkNamespace with its multi-personality
disorder.
This patch:
- removes Sandbox.Bridge() and makes it a regular function (WithIsBridge)
- removes Sandbox.Master() and makes it a regular function (WithMaster)
- removes Sandbox.MacAddress() and makes it a regular function (WithMACAddress)
- removes Sandbox.Address() and makes it a regular function (WithIPv4Address)
- removes Sandbox.AddressIPv6() and makes it a regular function (WithIPv6Address)
- removes Sandbox.LinkLocalAddresses() and makes it a regular function (WithLinkLocalAddresses)
- removes Sandbox.Routes() and makes it a regular function (WithRoutes)
- removes Sandbox.InterfaceOptions().
- removes the IfaceOptionSetter interface.
Note that the IfaceOption signature was changes as well to allow returning
an error. This is not currently used, but will be used for some options
in the near future, so adding that in preparation.

osl.NewSandbox() always returns a nil interface on Windows (and other non-Linux
platforms). This means that any code that these fields are always nil, and
any code using these fields must be considered Linux-only.

osl.NewSandbox() always returns a nil interface on Windows (and other non-Linux
platforms). This means that any code that these fields are always nil, and
any code using these fields must be considered Linux-only;
- libnetwork/Controller.defOsSbox
- libnetwork/Sandbox.osSbox
Ideally, these fields would live in Linux-only files, but they're referenced
in various platform-neutral parts of the code, so let's start with moving
the initialization code to Linux-only files.

Prior to moby/moby#44968, libnetwork would happily accept a ChildSubnet
with a bigger mask than its parent subnet. In such case, it was
producing IP addresses based on the parent subnet, and the child subnet
was not allocated from the address pool.
This commit automatically fixes invalid ChildSubnet for networks stored
in libnetwork's datastore.

This functionality has been replaced with Controller.GetSandbox, and is
no longer used anywhere.

- the SandboxWalker type

Various parts of the code were using "walkers" to iterate over the
controller's sandboxes, and the only condition for all of them was
to find the sandbox for a given container-ID. Iterating over all
sandboxes was also sub-optimal, because on Windows, the ContainerID
is used as Sandbox-ID, which can be used to lookup the sandbox from
the "sandboxes" map on the controller.
This patch implements a GetSandbox method on the controller that
looks up the sandbox for a given container-ID, using the most optimal
approach (depending on the platform).
The new method can return errors for invalid (empty) container-IDs, and
a "not found" error to allow consumers to detect non-existing sandboxes,
or potentially invalid IDs.
This new method replaces the (non-exported) Daemon.getNetworkSandbox(),
which was only used internally, in favor of directly accessing the
controller's method.
