Neither change is significant - just returning immediately when

When checking the setting of accept_ra, we have assumed that all
routes have a single nexthop, so the interface of the route would be
in the RTA_OIF attribute of the netlink RTM_NEWROUTE message. But
multipath routes don't have an RTA_OIF; instead, they have an
RTA_MULTIPATH attribute, which is an array of rtnexthop, with each
rtnexthop having an interface. This patch adds a loop to look at the
setting of accept_ra of the interface for every rtnexthop in the
array.

The feature was added to QEMU in 3.1.0 and it is currently blocking
migration, which is expected to change in the future. Luckily 3.1.0 is
new enough to give us migratability hints on each feature via
query-cpu-model-expension, which means we don't need to use the
"migratable" attribute on the CPU map XML.

The kernel calls this feature arch_capabilities and RHEL/CentOS 7.* use
arch-facilities. Apparently some CPU test files were gathered with the
RHEL version of QEMU. Let's update the test files to avoid possible
confusion about the correct naming.

prefix and interface id that qemu reports in
RDMA_GID_STATUS_CHANGED event. We also report them in some debug

depending on the host architecture and hence we wouldn't know
which format to use. Switch to ULL which is big enough and

This event is emitted on the monitor when a GID table in pvrdma device
is modified and the change needs to be propagate to the backend RDMA
device's GID table.

The control over the RDMA device's GID table is done by updating the
device's Ethernet function addresses.
Usually the first GID entry is determine by the MAC address, the second
by the first IPv6 address and the third by the IPv4 address. Other
entries can be added by adding more IP addresses. The opposite is the
same, i.e. whenever an address is removed, the corresponding GID entry
is removed.

The process is done by the network and RDMA stacks. Whenever an address
is added the ib_core driver is notified and calls the device driver's
add_gid function which in turn update the device.

To support this in pvrdma device we need to hook into the create_bind
and destroy_bind HW commands triggered by pvrdma driver in guest.
Whenever a changed is made to the pvrdma device's GID table a special
QMP messages is sent to be processed by libvirt to update the address of
the backend Ethernet device.

Commit 0c6ad476 updated gnulib, which rearranged some of the
conditions in gnulib wrapper headers such that compilation
started failing on BSD systems when the normal system <unistd.h>
tried to include another system header but instead got a
gnulib wrapper header in an incomplete state; this is because
gnulib headers only work if <config.h> is included first.

Commit b6f78259 papered over the symptoms of that by including
<config.h> in all the examples.  But this logic is backwards -
if our examples are truly meant to be stand-alone, they should
NOT depend on how libvirt was configured, and should NOT
depend on the gnulib fixes for system quirks.  In particular,
if an example does not need to link against libgnulib.la,
then it also does not need to use -Ignulib in its compile
flags, and likewise does not need to include <config.h> since
none of the gnulib wrapper headers should be interfering.

So, revert (most of) b6f78259 (except for the bogus pre-patch
use of "config.h" in admin/logging.c: if config.h is included,
it should be via <> rather than "", and must be before any
system headers); then additionally nuke all mention of
<config.h>, -Ignulib, and -llibgnu.la, making all of the
examples truly standalone.

Pulling in gnulib just for the <verify.h> header is rather
expensive, especially since that header does not require us
to link against gnulib.  It's better to make the event-test
example be standalone by just open-coding a more limited form
of a verify() macro that depends on modern gcc (we have enough
CI coverage that even though the verify is now a no-op in
older setups, we will still notice if we fail to add an event
- as a quick test, I was still able to provoke a compile
failure on Fedora 29 when deleting a line from domainEvents).
