Revert "bsd-user: replace fprintf(stderr, ...) with error_report()"

This reverts commit 1fba509527beb74bdcf50bc07ad3cd8244ad9c61.

That commit converted various fprintf(stderr, ...) calls to
use error_report(); however none of these bsd-user files include
a header which gives a prototype for error_report, so this
causes compiler warnings. Since these are just straightforward
reporting of command line errors, we should handle these in the
obvious way by printing to stderr, as we do for linux-user.
There's no need to drag in the error-handling framework for this,
especially since user-mode doesn't have the "maybe we need to
send this to the monitor" issues system emulation does.

qemu-img: Report error even with --oformat=json

img_check() should report that the format of the given image does not
support checks even if JSON output is desired. JSON data is output to
stdout, as opposed to error messages, which are (in the case of
qemu-img) printed to stderr. Therefore, it is easy to distinguish
between the two.

Also, img_info() does already use error_report() for human-readable
messages even though JSON output is desired (through
collect_image_info_list()).

vfio: Add guest side IOMMU support

This patch uses the new IOMMU notifiers to allow VFIO pass through devices
to work with guest side IOMMUs, as long as the host-side VFIO iommu has
sufficient capability and granularity to match the guest side. This works
by tracking all map and unmap operations on the guest IOMMU using the
notifiers, and mirroring them into VFIO.

There are a number of FIXMEs, and the scheme involves rather more notifier
structures than I'd like, but it should make for a reasonable proof of
concept.

vfio: Create VFIOAddressSpace objects as needed

So far, VFIO has a notion of different logical DMA address spaces, but
only ever uses one (system memory).  This patch extends this, creating
new VFIOAddressSpace objects as necessary, according to the AddressSpace
reported by the PCI subsystem for this device's DMAs.

This isn't enough yet to support guest side IOMMUs with VFIO, but it does
mean we could now support VFIO devices on, for example, a guest side PCI
host bridge which maps system memory at somewhere other than 0 in PCI
space.

vfio: Introduce VFIO address spaces

The only model so far supported for VFIO passthrough devices is the model
usually used on x86, where all of the guest's RAM is mapped into the
(host) IOMMU and there is no IOMMU visible in the guest.

This patch begins to relax this model, introducing the notion of a
VFIOAddressSpace.  This represents a logical DMA address space which will
be visible to one or more VFIO devices by appropriate mapping in the (host)
IOMMU.  Thus the currently global list of containers becomes local to
a VFIOAddressSpace, and we verify that we don't attempt to add a VFIO
group to multiple address spaces.

For now, only one VFIOAddressSpace is created and used, corresponding to
main system memory, that will change in future patches.

vfio: Fix 128 bit handling

Upcoming VFIO on SPAPR PPC64 support will initialize the IOMMU
memory region with UINT64_MAX (2^64 bytes) size so int128_get64()
will assert.

The patch takes care of this check. The existing type1 IOMMU code
is not expected to map all 64 bits of RAM so the patch does not
touch that part.

memory: Sanity check that no listeners remain on a destroyed AddressSpace

At the moment, most AddressSpace objects last as long as the guest system
in practice, but that could well change in future.  In addition, for VFIO
we will be introducing some private per-AdressSpace information, which must
be disposed of before the AddressSpace itself is destroyed.

To reduce the chances of subtle bugs in this area, this patch adds
asssertions to ensure that when an AddressSpace is destroyed, there are no
remaining MemoryListeners using that AS as a filter.

vfio-pci: Quirk RTL8168 NIC

This device is ridiculous.  It has two MMIO BARs, BAR4 and BAR2.  BAR4
hosts the MSI-X table, so oviously it would be too easy to access it
directly, instead it creates a window register in BAR2 that, among
other things, provides access to the MSI-X table.  This means MSI-X
doesn't work in the guest because the driver actually manages to
program the physical table.  When interrupt remapping is present, the
device MSI will be blocked.  The Linux driver doesn't make use of this
window, so apparently it's not required to make use of MSI-X.  This
quirk makes the device work with the Windows driver that does use this
window for MSI-X, but I certainly cannot recommend this device for
assignment (the Windows 7 driver also constantly pokes PCI config
