Our STREQ_NULLABLE and STRNEQ_NULLABLE macros are too
complicated. This was a result of some broken version of gcc.
However, that is long gone and therefore we can simplify the
macros.

In the Makefile in tests/ we initialize couple of variables like
test_programs, test_libraries and test_helpers. These variables
contain all the targets that we need to build in order to run
the test suite. So we initialize test_programs and test_helpers
and then conditionally add targets to them depending on what we
are building with. Then we repeat the same process with
test_libraries. It makes no sense to have two separate if-endif
sequences.

(and indeed it passes on Linux, GNU/kFreeBSD, and FreeBSD).

Also remove the WITH_DBUS conditional, as the test is already built
based on that conditional.

If the allocation fails in DO_TEST_FLUSH_PROLOGUE, then 'mgr == NULL',
but the code continues on - which won't be good. So modify the macro
to cause an immediate failure and jump to a cleanup label.

Found by Coverity as FORWARD_NULL event.

If you've ever tried running a huge page backed guest under
different user than in qemu.conf, you probably failed. Problem is
even though we have corresponding APIs in the security drivers,
there's no implementation and thus we don't relabel the huge page
path. But even if we did, so far all of the domains share the
same path:

   /hugepageMount/libvirt/qemu

Our only option there would be to set 0777 mode on the qemu dir
which is totally unsafe. Therefore, we can create dir on
per-domain basis, i.e.:

   /hugepageMount/libvirt/qemu/domainName

and chown domainName dir to the user that domain is configured to
run under.

Since the great rework of how we store vcpu- and iothread-related
data, we have overly complex part of code that is trying to format the
scheduler tuning data in as less lines as possible by grouping
settings for multiple threads.  That was designed as an input syntax
sugar for users, but we don't need to also use that when formatting
the XML.  Switching to simple enumeration makes the code nicer,
shorter and more welcoming to future changes.

Qemu 2.8.0+ changes arguments structure for blockdev-add in the effort
to make it finally stable. Since libvirt recently added the detection of
gluster debug support relying on the old syntax we need to add the new
as well.

Qemu decided to change a parameter name in rc-state which was not
captured by the 2.8.0 data. Bump it to current version.

So far the NSS module looks up only hostnames as provided by
guests themselves. However, there are some cases where this is
not enough: e.g. when there's a fresh new guest being installed
(with some generic hostname) say from a live ISO image; or some
(older) systems don't advertise their hostname in DHCP
transactions at all.
In cases like that it would be helpful if we translate domain
name as seen by libvirt too so that users can:

  # virsh start $dom && ssh $dom

In order to achieve that new libvirt-guest module is introduced,
while older libvirt module maintains its current behaviour (that
is translating guest provided names into IP addresses).

The name of the exported functions for an NSS module is quite
fixed, it is derived from the module name:

  _nss_$module_$function

Since we will create another NSS module with very similar
implementation we might as well generate the function names at
the compile time.

This module will be used to track:

  <domain, mac address list>

pairs. It will be important to know these mappings without
libvirt connection (that is from a JSON file), because NSS
module will use those to provide better host name translation.

Problem with VIR_FREE() is that we are not linking
libvirt-utils.so to our mock libs therefore there will be an
unresolved symbol. Fortunately, nsstest that eventually links
with the nssmock links also with libvirt-utils.so and thus the
symbol is resolved after all. However, if one wants to run the
test binary under valgrind it is impossible to do so. Because of
the unresolved symbol.
