     [auth2.c dispatch.c dispatch.h kex.c]
     a single dispatch_protocol_error() that sends a message of type 'UNIMPLEMENTED'
     dispatch_range(): set handler for a ranges message types
     use dispatch_protocol_ignore() for authentication requests after
     	successful authentication (the drafts requirement).
     serverloop/clientloop now send a 'UNIMPLEMENTED' message instead of exiting.
