After a nice long brainstorming session with @shykes on IRC, we decided on using a SHA1 hash of dockerinit compiled into the dynamic docker binary to ensure that we always use the two in a perfect pair, and never mix and match.

This allows docker-init to not import the main docker
module, which means it won't e.g. pick up any sqlite
dependencies.

- For the TCP test try again if socat wasn't listening yet;
- For the UDP test raise the timeout to a minute to workaround what
seems to be an issue with Linux.

API Changes
-----------
The port notation is extended to support "/udp" or "/tcp" at the *end*
of the specifier string (and defaults to tcp if "/tcp" or "/udp" are
missing)
`docker ps` now shows UDP ports as "frontend->backend/udp". Nothing
changes for TCP ports.
`docker inspect` now displays two sub-dictionaries: "Tcp" and "Udp",
under "PortMapping" in "NetworkSettings".
Theses changes stand true for the values returned by the HTTP API too.
This changeset will definitely break tools built upon the API (or upon
`docker inspect`). A less intrusive way to add UDP ports in `docker
inspect` would be to simply add "/udp" for UDP ports but it will still
break existing applications which tries to convert the whole field to an
integer. I believe that having two TCP/UDP sub-dictionaries is better
because it makes the whole thing more clear and more easy to parse right
away (i.e: you don't have to check the format of the string, split it
and convert the right part to an integer)
Code Changes
------------
Significant changes in network.go:
- A second PortAllocator is instantiated for the UDP range;
- PortMapper maintains separate mapping for TCP and UDP;
- The extPorts array in NetworkInterface is now an array of Nat objects
(so we can know on which protocol a given port was mapped when
NetworkInterface.Release() is called);
- TCP proxying on localhost has been moved away in network_proxy.go.
localhost proxy code rewrite in network_proxy.go:
We have to proxy the traffic between localhost:frontend-port and
container:backend-port because Netfilter doesn't work properly on the
loopback interface and DNAT iptable rules aren't applied there.
- Goroutines in the TCP proxying code are now explicitly stopped when
the proxy is stopped;
- UDP connection tracking using a map (more infos in [1]);
- Support for IPv6 (to be more accurate, the code is transparent to the
Go net package, so you can use, tcp/tcp4/tcp6/udp/udp4/udp6);
- Single Proxy interface for both UDP and TCP proxying;
- Full test suite.

For structs protected by a single mutex, embed the mutex for more
concise usage.
Also use a sync.Mutex directly, rather than a pointer, to avoid the
need for initialization (because a Mutex's zero-value is valid and
ready to be used).
