5b3acc15d1 libnetwork: drop legacy driver cruft
...that Swarmkit no longer needs now that it has been migrated to use
the new-style driver registration APIs.

a08a254df3 libnetwork: drop DatastoreConfig discovery type
The DatastoreConfig discovery type is unused. Remove the constant and
any resulting dead code. Today's biggest loser is the IPAM Allocator:
DatastoreConfig was the only type of discovery event it was listening
for, and there was no other place where a non-nil datastore could be
passed into the allocator. Strip out all the dead persistence code from
Allocator, leaving it as purely an in-memory implementation.

There is no more need to check the consistency of the allocator's
bit-sequences as there is no persistent storage for inconsistent bit
sequences to be loaded from.

d478e13639 libnet: un-plumb datastores from IPAM inits
The datastore arguments to the IPAM driver Init() functions are always
nil, even in Swarmkit. The only IPAM driver which consumed the
datastores was builtin; all others (null, remote, windowsipam) simply
ignored it. As the signatures of the IPAM driver init functions cannot
be changed without breaking the Swarmkit build, they have to be left
with the same signatures for the time being. Assert that nil datastores
are always passed into the builtin IPAM driver's init function so that
there is no ambiguity the datastores are no longer respected.

Add new Register functions for the IPAM drivers which are free from the
legacy baggage of the Init functions. (The legacy Init functions can be
removed once Swarmkit is migrated to using the Register functions.) As
the remote IPAM driver is the only one which depends on a PluginGetter,
pass it in explicitly as an argument to Register. The other IPAM drivers
should not be forced to depend on a GetPluginGetter() method they do not
use (Interface Segregation Principle).

540d1e0561 libnw: untangle IPAM allocator from global state
ipam.Allocator is not a singleton, but it references mutable singleton
state. Address that deficiency by refactoring it to instead take the
predefined address spaces as constructor arguments. Unfortunately some
work is needed on the Swarmkit side before the mutable singleton state
can be completely eliminated from the IPAMs.

a0a473125b Fix libnetwork imports
After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.

52e85b4b9a Global Default Address Pool support
This change brings global default address pool feature into
libnetwork. Idea is to reuse same code flow and functions that were
implemented for local scope default address pool.
Function InitNetworks carries most of the changes. local scope default
address pool init should always happen only once. But Global scope
default address pool can be initialized multiple times.

22801e071f Remove pre-defined networks from package init
This moves the initialization of the pre-defined networks to where it's
used instead of in package init.
This reason for this change is having this be populated in `init()`
causes it to always consume cpu, and memory (4.3MB of memory), to
populate even if the package is unused (like for instnace, in a re-exec).

Here is a memory profile of docker/docker just after starting the daemon of the
top 10 largest memory consumers:

         0     0% 89.66%   557.26kB 11.25%  main.init
```

Now, of course the docker daemon will still need to consume this memory, but
at least now re-execs and such won't have to re-init these variables.
