* Fully switch to the Haiku message format so that it is also used for on-disk

storage.
* Remove reduntant information from the header (field_count vs. fields_size).
* Remove checksums previously used to validate the message passing by area
  mechanism.
* Move variables that are purely used by the instance out of the header and into
  the BMessage object.
* Use more sensible types for the different message fields.
* Reduce some field sizes to realistic values.
* Make size_t values into uint32 values so the message format will not change
  when later moving to 64 bits.
* Pack the structures used for flat message storage so it doesn't change
  because of padding.
* Fix message passing by area. It never worked because the created area was
  never actually filled with any data!
* Some more allocation checks with graceful fallbacks (should be all now).
* Some more checks for negative index values (should also be all now).
* Make printing more inline with how the rest of the class works and make some
  of the output more consistent.
* Also add the new unsigned types to PrintToStream() output.
* Fix printing of unknown types and invalid BMessages, it would always have
  printed only the first entry respectively the same error.
* Added some clarifying comments.
* Cleanup.
