Instead of copying the default default values upfront
and then wondering whether the user has given us a new default,
leave the per-usage TLS certdirs and secrets empty during
parsing and only fill them afterwards if they weren't provided
by the user.

This means that instead of looking whether the specific certdir
paths match the default default, the Validate function (which
is called in between parsing and setting the defaults) can error
out for missing directories if the value is present, because
it must've come from the user.

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.

qemuAgentGetInterfaces calls qemuAgentCommand with needReply=false,

Set needReply to true, since we dereference it right after.

prefix and interface id that qemu reports in
RDMA_GID_STATUS_CHANGED event. We also report them in some debug
messages. This poses a problem because uint64_t can be UL or ULL
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.
