The DBI stream contains a lot of bookkeeping information for other streams.  In particular it contains information about section contributions and linked modules.  This patch is a first attempt at parsing some of the information out of the DBI stream.  It currently only parses and dumps the headers of the DBI stream, so none of the module data or section contribution data is pulled out.  This is just a proof of concept that we understand the basic properties of the DBI stream's metadata, and followup patches will try to extract more detailed information out.
