Kevin O'Connor 2a6a9eb52f pru: Avoid calling "slp" instruction on pru0 
If pru0 waits in sleep mode then a full beaglebone reboot is needed to
reprogram the pru0 firmware.  For now, avoid using the "slp"
instruction as a workaround.

Kevin O'Connor d618affd63 pru: Batch outgoing writes 
Allow pru0 to gather multiple outgoing message blocks into a single
rpmsg.  This can reduce communication overhead.

Kevin O'Connor 7b7f57e01c pru: Only sleep the pru0 if the incoming queue is fully empty 
It's possible for multiple blocks to be pending on the incoming
"rpmsg" stream.  Don't sleep unless the input is confirmed to be
empty.

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.
