Now that listeners is no longer an internal of the client, make it less
Docker-specific (despite there still being some open questions as how to
deal with some of the warnings that listeners has to emit). We should
move as much of the Docker-specific stuff (especially the port
allocation) to docker/ where it belongs (or maybe pass a check function).

pkg/ is a collection of utility packages used by the Docker project without being specific to its internals.
Utility packages are kept separate from the docker core codebase to keep it as small and concise as possible.
If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the
Docker organization, to facilitate re-use by other projects. However that is not the priority.
The directory pkg is named after the same directory in the camlistore project. Since Brad is a core
Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!
Because utility packages are small and neatly separated from the rest of the codebase, they are a good
place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
