Rather than re-execing docker as the proxy, create a new command docker-proxy
that is much smaller to save memory in the case where there are a lot of
procies being created. Also allows the proxy to be replaced, for example
in Docker for Mac we have a proxy that proxies to osx instead of locally.
This is the vendoring pull for https://github.com/docker/docker/pull/23312

Convert all networkdb core message types from go message types to
protobuf message types. This faciliates future modification of the
message structure without breaking backward compatibility.

- The pool request code does not behave properly in
case of concurrent requests when client does not
specify a preferred pool. It may dispense the same
predefined pool to different networks.
- The issue is common for local and global
address spaces

The default make target should be `all` by convention but
since it is not the first target it wasn't getting triggered
as the default target. Fixed the makefile to make `all`
the first and default target.

Compile the dnet tool for Linux (x86, amd64 and arm)
and Windows (x86 and amd64)
- Moved installation of dependencies into `Dockerfile.build`
- Remove `start-services` from Makefile
- That's the responsibility of Docker or build environment
- Removed utils depending on `netlink` from `netutils/utils.go`
Unable to add `make cross` to CircleCI just yet as there are some
issues to solve that are unrelated to this PR
Also fix `.gitignore` which was not updated after changing the build
image name in #667

This commit adds a basic overlay network
connectivity integration test. By doing this
it adds the basic functions to form a crude
container to run the networking tests. The container
uses a busybox rootfs with network namespace and
/etc/hosts and /etc/resolv.conf generated by
libnetwork.

- Create a wrapper script to run intergation tests
so that setups and teardowns happen in more
optimal manner
- Add traps to cleanup containers on failure or
user interrupt
- Introduce basic multi-node integration tests
- Removed default network, default driver tests
as they may not be useful in the near future

Updated Godeps and added codegangsta/cli into Godeps.
Also cleaned up the unnecessary packages by removing
host_discovery build tag which wasn't getting detected
by godep and was causing all sorts of `godep save` issues.
With this fix committers can do `godep save ./...` freely
to include their new dependencies without any failure.

Currently libnetwork does not have any integration test infra
support to tests libnetwork code end2end purely as a black
box. This initial commit adds the infra support to enable
test cases for this.

Currently when libnetwork tests are run inside a container
you cannot interrupt them in the middle by pressing ctrl-c
even though all the tests run in foreground. Fix this by running
tests by wrapping the make invocation inside the container
with a shell scripts which installs the SIGINT handler.
Without the handler the kernel does not deliver signals
to the process with PID 1(which in this case was make itself)
and hence make could never be interrupted. With this fix
we capture SIGINT in the shell script and re-raise it in the
the child process (which is make) and that makes the make
interruptible.

In prep for the UI/API updates on Docker to integrate the network and
endpoints, this PR removes the experimental tag from dnet and moving it
to docker UI and API and wrap the top-level "network" and "service"
under experimental.

In order to vendor-in libnetwork to docker, we need to remove the swarm
dependency even though it is used as library. using this PR, a new build
flag libnetwork_discovery is introduced in order to avoid pulling in the
unused hostdiscovery functionality into docker.
We are working with the Swarm project to see if we can modularize the
discovery package to become independent so that we can include them as a
vendor-in package in docker.

The libnetwork test does not need to run inside a namespace
when inside a container. This results in unpredictable behavior
when the sandbox code unlocks the go routine from the OS thread
while the test code still wants it locked in the OS thread. This
will result in unreachable interfaces when the go routine
migrates to a different OS thread.
Fixed by passing a special test flag which is only set to true
when the test is run inside a container.

- Refactored the Join/Leave code so they are synchronized across multiple go-routines
- Added parallel test coverage to test mult-thread access to Join/Leave
- Updated sandbox code to revert back to caller namespace when removing interfaces
- Changed the netns path to /var/run/netns so the cleanup is simpler on machine
reboot scenario

If we can't upload to coveralls, don't fail the build.
Goveralls and Coveralls have been a little flaky and started throwing
http 422 errors, although I still see coverage being reported.
It's best in the interim to ignore these, although this should be
removed in future when the service is more stable
