[interfacekit] Flattened BMessages

Has anyone looked into the flattened BMessage format yet? I wrote a BMessage
implementation, but flattening and unflattening is still not compatible.

This is what I found out for a message like the one posted at
http://www.freelists.org/archives/openbeos/05-2002/fullthread209.html:

                8               padded string?

Some of the header information and the count for the entry_hdr structs is
still missing. Any ideas?
