node: add flags to port_use_buffer

Browse source 
Remove the CAN_USE_BUFFERS flag, it is redundant. We can know this
because of the IO params and buffer params.

Add flags to the port_use_buffer call. We also want this call to
replace port_alloc_buffer. Together with a new result event we can
ask the node to (a)synchronously fill up the buffer data for us. This
is part of a plan to let remote nodes provide buffer data.
