b38c6b6ad3 util: sysinfo: Reduce amount of conditionally compiled code
Whole implementations along with helper totalling screens of code were
conditionally compiled. That made the code totally unreadable and
untestable. Rename functions to have the architecture in the name so
that all can be compiled at the same time and introduce header to allow
testing them all.

3898526931 make all struct typedefs comply with proposed coding conventions
Proposed formal coding conventions encourage defining typedefs for
vir[Blah] and vir[Blah]Ptr separately from the associated struct named
_vir[Blah]:

    typedef struct _virBlah virBlah;
    typedef virBlah *virBlahPtr;
    struct _virBlah {
    ...
    };

At some point in the past, I had submitted several patches using a
more compact style that I prefer, and they were accepted:

    typedef struct _virBlah {
        ...
    } virBlah, *virBlahPtr;

Since these are by far a minority among all struct definitions, this
patch changes all those definitions to reflect the style prefered by
the proposal so that there is 100% consistency.

        goto cleanup;
    }

Make some common helpers which will use the pattern and make a single
reference using a single common error message.

Altered for Interfaces, Storage Pools, Storage Volumes, and Node Devices.

For each the common error message can now also indicate which 'name' was
not found. For Storage Volumes, the "new" error will be more specific
rather than just invalid argument.

d065934cd0 cputest: Switch host CPU data scripts to model expansion
Instantiating "host" CPU and querying it using qom-get has been the only
way of probing host CPU via QEMU until 2.9.0 implemented
query-cpu-model-expansion for x86_64. Even though libvirt never really
used the old way its result can be easily converted into the one
produced by query-cpu-model-expansion. Thus we can reuse the original
test data and possible get new data from hosts where QEMU does not
support the new QMP command.

bb3363c90b qemu: Use full CPU model expansion on x86
The static CPU model expansion is designed to return only canonical
names of all CPU properties. To maintain backwards compatibility libvirt
is stuck with different spelling of some of the features, but we need to
use the full expansion to get the additional spellings. In addition to
returning all spelling variants for all properties the full expansion
will contain properties which are not guaranteed to be migration
compatible. Thus, we need to combine both expansions. First we need to
call the static expansion to limit the result to migratable properties.
Then we can use the result of the static expansion as an input to the
full expansion to get both canonical names and their aliases.

f013828992 qemu: Get host CPU model from QEMU on x86_64
Until now host-model CPU mode tried to enable all CPU features supported
by the host CPU even if QEMU/KVM did not support them. This caused a
number of issues and made host-model quite unreliable. Asking QEMU for
the CPU it can provide and the current host makes host-model much more
robust.

This commit fixes the following bugs:

    https://bugzilla.redhat.com/show_bug.cgi?id=1018251

when an unsupported feature is explicitly requested:

66c806009d test: fix pcie-root-port-too-many test
While reviewing a patch from Andrea that modified this test case, I
realized that although it was "properly failing" (it's a negative
test), that it was failing for the wrong reason (the MULTIFUNCTION cap
wasn't set in the test case, so it was saying that multifunction=on
wasn't supported by the QEMU binary; instead it should have been
complaining that it had run out of PCI slots of the appropriate type
and couldn't automatically add any more).

This improper failure had started when I added the patch to
automatically aggregate pcie-root-ports onto multiple functions of
each pcie-root slot, but I hadn't noticed it because the test still
failed.

This patch corrects the test case to 1) set the MULTIFUNCTION flag in
the caps, and 2) attempt to add 241 pcie-root-ports to a domain. Since
there are 30 slots available on a pcie-root (slot 0 is reserved, and
slot 31 is used by the integrated SATA controller), and a
pcie-root-port can only be placed on a function of a slot on
pcie-root, the maximum number of pcie-root-ports in any domain is 240.

2d8fbeb8a5 Fix location of blkid.h in include header
The build system for libvirt correctly detects the location of blkid
using PKG_CONFIG_PATH environment variable. The file blkid.pc states
that the include flags should be: 'Cflags: -I${includedir}/blkid' but
libvirt searches for blkid.h inside ${includedir}/blkid/blkid, which is
wrong. Until now, the compilation for libvirt succeeded because of pure
luck, as it had -I/usr/include as a CFLAG. This issue was faced while
compiling libvirt on Ubuntu 16.04.2 with bare minimum dev packages and a
custom compiled blkid kept in a non-standard $prefix.
