Log Message:
Implement a new device buffer queue interface.
One basic struct, a function to setup a queue with a specific strategy and
three macros to put buf's into the queue, get and remove the next buf or
get the next buf without removal.

The BUFQ_XXX interface will be removed in the future.
The B_ORDERED flag is not longer supported.
