an [abandoned] attempt to slice out the docker/docker/pkg package
f35a0f3210
This patches avoids registering (and calling) the same plugin more than
once. Using an helper map which indexes by name guarantees this and keeps
the order.
The behavior of overriding the same name in a flag is consistent with,
for instance, the `docker run -v /test -v /test` flag which register
the volume just once.
Adds integration tests.

Also removes a somehow duplicate debug statement (leaving only the
second one as it's a loop of plugin's manifest):

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!
