Added Jack Burton's DataIO-related stuff and cleaned things up a bit.
Several files managed to get left out of the build process; changes to support.src fixed that. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@930 a95241bf-73f2-0310-859d-f6bbb57e9c96

// BMallocIO and BMemoryIO classes implement the protocol,
