6512a2a710 Implement cancellation method for dma async I/O (Avi Kivity) 
Move the dma helpers to a private aio pool, and implement a cancellation
method for them.  Should prevent issues when cancelling I/O while dma is
in progress.

59a703ebaa Introduce block dma helpers (Avi Kivity) 
These helpers perform read/write requests on entire scatter/gather lists,
relieving the device emulation code from mapping and unmapping physical
memory, and from looping when map resources are exhausted.

244ab90e17 Add a scatter-gather list type and accessors (Avi Kivity) 
Scatter-gather lists are used extensively in dma-capable devices; a
single data structure allows more code reuse later on.
