86c84f6ae0 IPC: new auth improvement and limits work around. 
Create the queues/ringbuffers on the server so we don't
have to modify proc entries. Then chown them so that
the clients can access them.

bd2c07f739 Add a ringbuffer based off the one in logsys. 
This ringbuffer is usable across processes.
the point is to use this for IPC to provide async
connections from client to server, but with inherient
flow control.

This still needs a bit of clean up, but committing now
for feedback and as it is quite functional.
