If we encounter an error setting an interface's IPv4 or IPv6 address,
log the addresses we tried to use using the %v specifier rather than %q.

- Attempt the veth delete only after both ends
are moved into the default network namespace.
Which is after both driver.Leave() and
sandbox.clearNetworkResources() are called.

Add support for overlay networking in older kernels.
Following were done to achieve this:
+ Create the vxlan network in host namespace.
+ This may create conflicts with other private
networks so check for conflicts and fail a
join if there is any conflict.
+ Add iptable based filtering to only allow
subnet bridges in the same network to forward
traffic while different network bridges will
not be able to forward b/w each other. Also
block traffic to overlay network originating
from the host itself.

- Consistently with what it does for IP addresses, libnetwork
will also program the container interface's MAC address with
the value set by network driver in InterfaceInfo.

Exposing osl package outside libnetwork is not neccessary and the
InterfaceStatistics anyways belong to the types package.

Fixes#485
The code previously relied on an uninteded side effect. When the
interface name was set, this causes the interface to come up
prematurely. Once that side effect was removed, routes could
no longer be set.
This change ensures that routes are only set after the interface
is brought up.

- Maps 1 to 1 with container's networking stack
- It holds container's specific nw options which
before were incorrectly owned by Endpoint.
- Sandbox creation no longer coupled with Endpoint Join,
sandbox and endpoint have now separate lifecycle.
- LeaveAll naturally replaced by Sandbox.Delete
- some pkg and file renaming in order to have clear
mapping between structure name and entity ("sandbox")
- Revisited hosts and resolv.conf handling
- Removed from JoinInfo interface capability of setting hosts and resolv.conf paths
- Changed etchosts.Build() to first write the search domains and then the nameservers
