Make dma_bdrv_io available for drivers, and pass an explicit I/O function instead of hardcoding bdrv_aio_readv/bdrv_aio_writev. This is required to implement non-READ/WRITE dma commands in the ide driver, e.g. the upcoming TRIM support.

In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Now that we have a separate aio pool structure we can remove those aio pool details from BlockDriver. Every driver supporting AIO now needs to declare a static AIOPool with the aiocb size and the cancellation method. This cleans up the current code considerably and will make it cleaner and more obvious to support two different aio implementations behind a single BlockDriver.

The block layer may signal an immediate error on an asynchronous request by returning NULL. The DMA API did not handle this correctly, returning an AIO request which would never complete (and which would crash if cancelled). Fix by detecting the failure and propagating it.

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.

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.

Scatter-gather lists are used extensively in dma-capable devices; a single data structure allows more code reuse later on.
