We optionally include QEMU and LXC support in this test and
depending on which is enabled (if either is enabled at all) we
need to link in different objects.

Right now we implicitly depend on the fact that qemu_LDADDS is
empty when QEMU is not enabled to get the correct set of objects,
but it's better to be explicit about it.

We want all test programs using qemu_LDADDS to also use LDADDS,
and cputest is the only existing exception.

We can't just replace GNULIB_LIBS with LDADDS though, even though
the latter is a superset of the former, because that would result
in a linking error due to including the same object twice:

  /usr/bin/ld:
  ../src/libvirt_probes.o:.../src/libvirt_probes.o.dtrace-temp.c:141:
  multiple definition of `libvirt_object_new_semaphore';
  ../src/libvirt_probes.o:.../src/libvirt_probes.o.dtrace-temp.c:141:
  first defined here

To work around this, we include both qemu_LDADDS and LDADDS when
QEMU support is enabled, and just LDADDS otherwise.

Add two capabilities for testing features required for the upcoming
virDomainBackupBegin: use block-dirty-bitmap-merge as the generic
witness of bitmap support needed for checkpoints (since all of the
bitmap management functionalities were finalized in the same qemu 4.0
release), and the bitmap parameter to nbd-server-add for pull-mode
backup support.  Even though both capabilities are likely to be
present or absent together (that is, it is unlikely to encounter a
qemu that backports only one of the two), it still makes sense to keep
two capabilities as the two uses are orthogonal (full backups don't
require checkpoints, push mode backups don't require NBD bitmap
support, and checkpoints can be used for more than just incremental
backups).

Existing code is not affected by the new capabilities.

Migration always uses a TCP socket for NBD servers, because we don't
support same-host migration. But upcoming pull-mode incremental backup
needs to also support a Unix socket, for retrieving the backup from

the monitor calls, since that is a nice reusable struct that can track
both TCP and Unix sockets.

The DO_TEST() macro in qemumonitorjsontest.c was not passing the

In the process of mechanically altering tests to pass the schema

Creating firewall rules for the virtual networks causes the kernel to
load the conntrack module. This imposes a significant performance
penalty on Linux network traffic. Thus we want to only take that hit if
we actually have virtual networks running.

We need to create global firewall rules during startup in order to
"upgrade" rules for any running networks created by older libvirt.
If no running networks are present though, we can safely delay setup
until the time we actually start a network.
