Instead of defining targets conditionally and depending on
them unconditionally, define a couple of variables and
conditionally add targets to them.
In addition to removing a bunch of useless code, this has
the nice effect of no longer requiring the main Makefile.am

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.

Since its introduction in commit 0977b8aa07 (released in v1.2.14)
qemuAgentGetInterfaces calls qemuAgentCommand with needReply=false,
which allows qemuAgentCommand to return 0 even when it did not get
any reply from the agent.
Set needReply to true, since we dereference it right after.
This can be hit if libvirt is waiting for an event from the agent
(e.g. shutdown) and the agent cannot reply in time (e.g. due to
the guest being shut down), as reported in:

In the previous commit we are using uint64_t for storing subnet
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.

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).

Similar to the gnulib changes we just incorporated into maint.mk,
it's time to use '$(VC_LIST) | xargs program' instead of
'program $$($(VC_LIST))', in order to bypass the problem of hitting
argv limits due to our large set of files.
Drop several uses of $$files as a temporary variable when we can
instead directly use xargs. While at it, fix a typo in the
prohibit_windows_special_chars error message.
Note that 'grep $pattern $(generate list)' has be be rewritten
as 'generate list | xargs grep $pattern /dev/null' - this is
because for a list that is just long enough, and without /dev/null,
xargs could make a worst-case split of 'grep $pattern all but one;
grep $pattern last' which has different output (grep includes the
filename when there was more than one file, but omits it for a
single file), while our conversion gives 'grep $pattern /dev/null
all but one; grep $pattern /dev/null last'. We are less concerned
about the empty list case (why would we run the syntax check if we
didn't have at least one file?), but grepping /dev/null happens to
produce no output and thus nicely also solves that problem without
relying on the GNU extension of 'xargs -r'.
