- Use a common struct for Volumes
- Split out some functionality in intializeVolume into separate functions
- Removes some duplicate code
- In general much easier to grok the code now

This PR moves the userland proxies for TCP and UDP traffic out of the
main docker daemon's process ( from goroutines per proxy ) to be a
separate reexec of the docker binary. This reduces the cpu and memory
needed by the daemon and if the proxy processes crash for some reason
the daemon is unaffected. This also displays in the standard process
tree so that a user can clearly see if there is a userland proxy that is
bound to a certain ip and port.

This also helps us to cleanly cleanup the proxy processes by stopping
these commands instead of trying to terminate a goroutine.

renaming this struct to more clearly be session, as that is what it
handles.
Splitting out files for easier readability.

* starting with filtering for exit codes. `docker ps -a --filter 'exited=1'`
* API doc for filter parameter
* formatting filters for help usage
* tweaks for review

Later versions of `apt` are smart enough to just create this directory if it's missing, but Lucid balks (just like `gnupg` and `gpgv` aren't in the Required set so don't come in a minbase -- good ol' Lucid).

This is an extremely tentative PR. However, I feel that the suggestions are generally good.
