Kevin O'Connor f8bd8b97be command: Don't pass max_size to command_encodef() 
The command_encodef() can read the max_size parameter directly from
the 'struct command_encoder' passed into it.  Also, there is no need
to check that a message will fit in a buffer if the buffer is declared
to be MESSAGE_MAX in size.

Kevin O'Connor e8356afa26 pru: Rework command processing so that most of it is done on pru0 
Change the command dispatch and response generation so that most of
the work is done on pru0 instead of pru1.  This allows more code to
fit into the limited space on pru1.
