ruby: declare all protocol message buffers as parameters

MessageBuffer is a SimObject now.  There were protocols that still declared
some of the message buffers are variables of the controller, but not as input
parameters.  Special handling was required for these variables in the SLICC
compiler.  This patch changes this.  Now all message buffers are declared as
input parameters.
