packer: Introduce idata_desc, data_desc and tables

This commit introduces three kinds of primitives: Internal data
descriptors (idata_desc), embeddable data descriptors (data_desc) and
data descriptor tables.

The internal data descriptors are used by the packer to keep state and
link information while the embeddable data descriptors mirror more
closely to what will actually be on disk.

There is a special %root% entry which should offset into a root file
containing information about the archive as a whole.
