Branch: yamt-lazymbuf
Description: implement and evaluate lazy mapping of mbuf external data pages
it's intended as the first step of larger changes.
1. support operations (esp. bus_dma load) on
unmapped mbuf.
2. unify mbuf and buf.
(or, at least some parts of them)
3. then it should be trivial to implement
i/o coalescing, etc.
