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

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 dependingon cpu.h, and this makes it necessary to compile these files per-target.However, fixing this does not belong in these patches....
ahci: Add migration support
Jason tested these patches by migrating Windows 7 and Fedora 17 guests(while under I/O) on both piix with ahci attached and on q35 (which hasa built-in AHCI controller).

ide/ahci: Use universal DMA helper functions
The AHCI device can provide both PCI and SysBus AHCI deviceemulations. For this reason, it wasn't previously converted to usethe pci_dma_*() helper functions. Now that we have universal DMAhelper functions, this converts AHCI to use them....
msi: Invoke msi/msix_reset from PCI core
There is no point in pushing this burden to the devices, they tend toforget to call them (like intel-hda, ahci, xhci did). Instead, resetfunctions are now called from pci_device_reset. They do nothing ifMSI/MSI-X is not in use....
msi: Invoke msi/msix_write_config from PCI core

Limit them to the device_add functionality. Device aliases were a hack basedon the fact that virtio was modeled the wrong way. The mechanism for aliasingis very limited in that only one alias can exist for any device....
qdev: register all types natively through QEMU Object Model
This was done in a mostly automated fashion. I did it in three steps and thenrebased it into a single step which avoids repeatedly touching every file inthe tree.
