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.

memory: give name to every AddressSpace
The "info mtree" command in QEMU console prints only "memory" and "I/O" address spaces while there are actually a lot more other AddressSpacestructs created by PCI and VIO devices. Those devices do not normallyhave names and therefore not present in "info mtree" output....
dma: eliminate old-style IOMMU support
The translate function in the DMAContext is now always NULL.Remove every reference to it.

pci: use memory core for iommu support
Use the new iommu support in the memory core for iommu support. The onlyuser, spapr, is also converted, but it still provides a DMAContextinterface until the non-PCI bits switch to AddressSpace.

pci: Teach PCI Bridges about VGA routing
Each PCI Bridge has a set of implied VGA regions that are enabled whenthe VGA bit is set in the bridge control register. This allows VGAdevices behind bridges. Unfortunately with VGA Enable, which weformerly allowed but didn't back, comes along some required VGA...

pci: Fix INTx routing notifier recursion
For some reason we recurse to fire the INTx routing notifier for eachchild of a bus, for each possible device of a bus. That means that ifwe add a root port, the notifier gets called for that bridge 256times. If we add an upstream switch behind that root port, 256^2. But...
pci: refuse empty ROM files
