At this point, all test programs that use qemu_LDADDS also

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.

Since the behaviour of launch security is heavily dependent on 3rd party
vendors (e.g. AMD SEV) where the data returned can be essentially
anything, the most reasonable approach here in the test driver is not to
try return any data.

The hash table returned by qemuMonitorGetAllBlockJobInfo is organized by
the frontend name (which skipps the 'drive-' prefix). While our code
properly matches the jobs to the disk, qemu needs the full job name
including the 'drive-' prefix to be able to identify jobs.

Fix this by adding an argument to qemuMonitorGetAllBlockJobInfo which
does not modify the job name before filling the hash.

This fixes a regression where users would not be able to cancel/pivot
block jobs after restarting libvirtd while a blockjob is running.

In commit 76b9aba2 I refactored how the function treats the readonly
flag which introduced a bug when we'd not allow to force read-write
state for an image.

This created problems with blockjobs where we need to temporarily
force images to have read-write permissions.

Rename QEMU_DOMAIN_STORAGE_SOURCE_ACCESS_READ_ONLY to
QEMU_DOMAIN_STORAGE_SOURCE_ACCESS_FORCE_READ_ONLY and also introduce
a complement QEMU_DOMAIN_STORAGE_SOURCE_ACCESS_FORCE_READ_WRITE which
will allow to force write access.

The upcoming virDomainBackup() API needs to take advantage of various

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 same host. Support this by plumbing virStorageNetHostDef through
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
schema through, which meant that we were not validating any of those
tests for correct usage according to the schema.

In the process of mechanically altering tests to pass the schema
through, use VIR_AUTOPTR on all of the affected test instances. The
next patch will do some further cleanups that it exposes.

Tested by using this hack, where the test mistakenly passed pre-patch,
but correctly diagnosed the garbage post-patch:
