dma: eliminate DMAContext

The DMAContext is a simple pointer to an AddressSpace that is now always
already available. Make everyone hold the address space directly,
and clean up the DMA API to use the AddressSpace directly.

ide/macio: fix wrong opaque with TRIM support

Commit 215e47b9 enabled TRIM by default, which revealed a bug in TRIM
support for the IDE macio emulation driver, introduced in d353fb72.

The call to dma_bdrv_io() is using a wrong opaque of type IDEState
instead of DBDMA_io. This patch fixes that....

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

Use DMADirection type for dma_bdrv_io

Currently dma_bdrv_io() takes a 'to_dev' boolean parameter to
determine the direction of DMA it is emulating. We already have a
DMADirection enum designed specifically to encode DMA directions.
This patch uses it for dma_bdrv_io() as well. This involves removing...

Many places in QEMU call qemu_aio_flush() to complete all pending
