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.

spapr_vio: take care of creating our own AddressSpace/DMAContext

Fetch the root region from the sPAPRTCETable, and use it to build
an AddressSpace and DMAContext.

Now, everywhere we have a DMAContext we also have access to the
corresponding AddressSpace (either because we create it just before...

memory: make section size a 128-bit integer

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes...

vfio: abort if an emulated iommu is used

vfio doesn't support guest iommus yet, indicate it to the user
by gently depositing a core on their disk.

spapr: convert TCE API to use an opaque type

The TCE table is currently returned as a DMAContext, and non-type-safe
APIs are called later passing back the DMAContext. Since we want to move
away from DMAContext, use an opaque type instead, and add an accessor...

spapr: make IOMMU translation go through IOMMUTLBEntry

The next step is to introduce the translation code that will be used for
IOMMU MemoryRegions, but still do the actual translation in a DMAContext.

spapr: use memory core for iommu support

Now we can stop using a "translating" DMAContext, but we do not yet modify
the sPAPRTCETable users to get an AddressSpace; they keep using the table
via a DMAContext.

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 only
user, spapr, is also converted, but it still provides a DMAContext
interface until the non-PCI bits switch to AddressSpace.

pc: Make -no-fd-bootchk stick across boot order changes

Option -no-fd-bootchk asks the BIOS to attempt booting from a floppy
even when the boot sector signature isn't there, by setting a bit in
RTC CMOS. It was added back in 2006 (commit 52ca8d6a).

Two years later, commit 0ecdffbb added monitor command boot_set....
