* Behind a pipe buffle handle there can be DMA buffers, client (or user)
* buffers, regular malloced buffers, etc. This file provides an abstract base
* buffer handle that allows the driver to cope with all those kinds of buffers
* in a more flexible way.
*
*
* There is no obligation of a winsys driver to use this library. And a pipe
* driver should be completly agnostic about it.
