Expose reading and writing ID mapping in the archive and chrootarchive
packages, and in the driver interface. Generally this means that
when computing or applying diffs, we need to have ID mappings passed in
that are specific to the layers we're using.

Add support to the Store objects for per-container UID/GID mapping.
* UID and GID maps can be specified when creating layers and containers.
* If mapping options are specified when creating a container, those
options are used for creating the layer which we create for the
container and recorded with the container for convenience.
* A layer defaults to using the ID mapping configured for its parent, or
to the default which was used to initialize the Store object if it has
no parent.
