* Ported over a simplified version (no message sending) of the current BMessage implementation to the build libbe
* Also ported over the new MessageAdapter class * Removed old BMessage implementation prototypes that apparently were left in the private folder git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21515 a95241bf-73f2-0310-859d-f6bbb57e9c96

// can be processed in a message loop. BMessage objects
|

// are also used as data containers by the archiving and

// the scripting mechanisms.
