On UEFI systems, the SMBIOS entry point (a.k.a. anchor) structures are
found similarly to the ACPI RSD PTR table(s): by scanning the
ConfigurationTable array in the EFI system table for well-known GUIDs.
Locate the SMBIOS 2.1 (32-bit) and 3.0 (64-bit) anchors in the
BiosTablesTest UEFI application, and report the addresses in new fields
appended to the BIOS_TABLES_TEST structure.

Both functions, object_initialize() and object_property_add_child() increase
the reference counter of the new object, so one of the references has to be
dropped afterwards to get the reference counting right. Otherwise the child
object might not be properly cleaned up when the parent gets destroyed.
Some functions of the pci-host devices miss to drop one of the references.
Fix it by using object_initialize_child() instead, which takes care of
calling object_initialize(), object_property_add_child() and object_unref()
in the right order.

Without the -Wno-typedef-redefinition option, clang complains if a typedef
gets redefined in gnu99 mode (since this is officially a C11 feature). This
used to also happen with older versions of GCC, but since we've bumped our
minimum GCC version to 4.8, all versions of GCC that we support do not seem
to issue this warning in gnu99 mode anymore. So this has become a common
problem for people who only test their code with GCC - they do not notice
the issue until they submit their patches and suddenly patchew or a
maintainer complains.
Now that we do not urgently need to keep the code clean from typedef
redefintions anymore with recent versions of GCC, we can ease the
situation with clang, too, and simply shut these warnings off for good.

Some machines (like the pxa2xx-based ARM machines) only have a sysbus
OHCI controller, but no PCI. With the new Kconfig-style build system,
it will soon be possible to create QEMU binaries that only contain
such PCI-less machines. However, the two OHCI controllers, for sysbus
and for PCI, are currently both located in one file, so the PCI code
is still required for linking here. Move the OHCI-PCI device code
into a separate file, so that it is possible to use the sysbus OHCI
device also without the PCI dependency.

The ohci_die() function always assumes to be running with a PCI OHCI
controller and calls the PCI-specific functions pci_set_word(). However,
this function might also get called for the sysbus OHCI devices, so it
likely fails in that case. To fix this issue, change the code now, so that
there are two implementations now, one for sysbus and one for PCI, and
use the right function via a function pointer in the OHCIState structure.

This patch fixes a few things in the way error codes are handled in
the qcow2 compression code:
a) qcow2_co_pwritev_compressed() expects qcow2_co_compress() to only
return -1 or -2 on failure, but this is not correct. Since the
change from qcow2_compress() to qcow2_co_compress() in commit
ceb029cd6f the new code can also return -EINVAL (although
there does not seem to exist any code path that would cause that
error in the current implementation).
b) -1 and -2 are ad-hoc error codes defined in qcow2_compress().
This patch replaces them with standard constants from errno.h.
c) Both qcow2_compress() and qcow2_co_do_compress() return a negative
value on failure, but qcow2_co_pwritev_compressed() stores the
value in an unsigned data type.

make_completely_empty() is an optimisated path for bdrv_make_empty()
where completely new metadata is created inside the image file instead
of going through all clusters and discarding them. For an external data
file, however, we actually need to do discard operations on the data
file; just overwriting the qcow2 file doesn't get rid of the data.
The necessary slow path with an explicit discard operation already
exists for other cases. Use it for external data files, too.

because we have done exactly that "convert" test earlier in 082 already.

there is no point in "amend" having a default format. The user has to

preallocate_co() already gave the data file the full size without
forwarding the requested preallocation mode to the protocol. When
bdrv_co_truncate() was called later with the preallocation mode, the
file didn't actually grow any more, so the data file stayed unallocated
even if full preallocation was requested.
Pass the right preallocation mode to preallocate_co() and remove the
second bdrv_co_truncate() to fix this. As a side effect, the ugly
one-byte write in preallocate_co() is replaced with a truncate call,
now leaving the last block unallocated on the protocol level as it
should be.

Limiting the allocation to INT_MAX bytes isn't particularly clever
because it means that the final cluster will be a partial cluster which
will be completed through a COW operation. This results in unnecessary
data read and write requests which lead to an unwanted non-sparse
filesystem block for metadata preallocation.
Align the maximum allocation size down to the cluster size to avoid this
situation.
