- IPv6 changes for bridge
- Convert unit tests to the new model

- DisableBridgeCreation is misleading. change it to DefaultBridge
- Dont fail the init if localstore cannot be initialized
- added a convenience function to get endpoint for a container

Replaced it with DisableBridgeCreation and it can be used ONLY in
a special case for docker0 bridge from docker, instead of calling it
from all other case.

- Do not discard errors on ip allocation for gw and bridge
- Release addresses on network delete
- Add some context on top of ipallocator returned error
- Create ip allocator instance at driver creation, not at package init,
otherwise this affects bridge test code where ip db is carried over
test functions

- NetworkRange() function on which ipallocatore relies
to compute the subnet limits has a bug in computing the upper limit IP
- in case container subnet is specified (fixedCIDR), bridge driver to
reserve bridge and gateway addresses only if they belong to the container
subnet
- Make ipallocator more robust in using converting the passed network
to a canonical one before using it as a key in its public APIs

Two changes were missing:
- On allocation of bridge ip was not passing canonical subnet
- Canonical subnet has to be passed on ip release
as well, otherwise ipallocator will attempt
ip release from a non registered nw

- Currently both network and host bits in the subnet are passed
when requesting an address from ipallocator.
The way ip allocator determines the first available
IP is tainted when caller passes the subnet host bits.
- Verified this patch applied to libnetwork vendored in docker
fixes the issue when starting the daemon.
- Fixes#287

- Package types to define the interfaces libnetwork errors
may implement, so that caller can categorize them.

using a len(net.IP) to check for ipv4 or ipv6 is a bad idea.
And that was exactly done in NetworkOverlaps() function with the
assumption that any ipv4 net.IP will be of 4 bytes. Golang Net package
makes no such assumptions.
This assumption actually broke a particular use-case where the
NetworkOverlaps fails to identify a genuine overlap and that causes
datapath issues.
With this fix, we explicitely check for v4 or v6

- Basically this is porting docker PR #9381 to libnetwork
- Added a Config.Validate() method where to consolidate
a priori validation of bridge configuration
- Have bridgeInterface store the current v4/v6 default gateways
- Introduced two setupStep functions to set the requested def gateways

- Added api enhancement to pass driver specific config
- Refactored simple bridge driver code for driver specific config
- Added an undocumented option to add non-default bridges without
manual pre-provisioning to help libnetwork testing
- Reenabled libnetwork test to do api testing
- Updated README.md

- Move ipallocator package into libnetwork
- Also ported network utility functions and their tests in libnetwork:
docker/daemon/networkdriver/utilg.go => libnetwork/utils.go
docker/daemon/networkdriver/network_test.go => libnetwork/utils_test.go
- Changed drivers/setup_device.go and setup_ipv4.go to reuse functions in
utils.go, instead of redefining internally.
- Modified utils to use vishvananda/netlink instead of libcontainer/netlink
