As part of a goal to eliminate the need to use virCapsPtr for anything
other than the virConnectGetCapabilies() API impl, cache the host arch
against the QEMU driver struct and use that field directly.

In the tests we move virArchFromHost() globally in testutils.c so that
every test runs with a fixed default architecture reported.

In cases when we call a libvirt helper which reports an error the error
would be hidden unless libvirt library debug is on. This produces a lot
of output and is hard to debug.

The helper provides a way to dispatch the libvirt error in specific
cases sice we do already dispatch it in case when virTestRun is used.

The OOM handling requires special build time options which we never
enable in our CI. Even once enabled the tests are incredibly slow and
typically require manual inspection of the results to weed out false
positives.

Since there was previous agreement to switch to abort on OOM in libvirt
code, there's no point continuing to keep the unused OOM testing code.

There is an inconsistency with VIR_TEST_DEBUG() calls. One half
(roughly) of calls does have the newline character the other one
doesn't. Well, it doesn't have it because it assumed blindly that
new line will be printed, which is not the case.

Test executables and mocks have assumption that any symbol can be
replaced with LD_PRELOAD. That's not a case for macOS unless flat
namespace is used, because every external symbol reference records the
library to be looked up. And the symbols cannot be replaced unless dyld
interposing is used.

Setting DYLD_FORCE_FLAT_NAMESPACE changes symbol lookup behaviour to be
similar to Linux dynamic linker. It's more lightweight solution than
explicitly decorating all mock symbols as interpositions and building
libvirt as interposable dynamic library.

This fixes vircryptotest and allows to proceed other tests that rely on
mocks a little bit further.

macOS has two kinds of loadable libraries: MH_BUNDLE, and MH_DYLIB.
bundle is used for plugins that are loaded with dlopen/dlsym/dlclose.
And there's no way to preload a bundle into an application. dynamic
linker (dyld) will reject it when finds it in DYLD_INSERT_LIBRARIES.

Unfortunately, a bundle is built if -module flag is provided to libtool.
The flag has been removed to build dylibs with ".dylib" suffix.

In preparation libtool "-module" flag removal, add lib prefix to all
mock shared objects.

While at it, introduce VIR_TEST_MOCK macros that makes path out of mock
name to be used with VIR_TEST_PRELOAD or VIR_TEST_MAIN_PRELOAD.  That,
hopefully, improves readability, reduces line length and allows to
tailor VIR_TEST_MOCK for specific platform if it has shared library
suffix different from ".so".

vircapstest has code to add a full host NUMA topology, that
is, one that includes all information about nodes and CPUs
including IDs; testQemuCapsInit(), which is used to create a
mock virCapsPtr for QEMU tests, however, just fakes it by
setting nnumaCell_max to some number.

While the latter approach has served us well so far, we're
going to need all the information to be filled in soon. In
order to do that, we can just move the existing code from
vircapstest to testutils and, with some renaming and
trivial tweaking, use it as-is.

Interestingly, the NUMA topology generated by the function
is rigged up so that the NUMA nodes aren't (necessarily)
numbered starting from 0, which is a nice way to spot
mistaken assumptions in our codebase.

Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

Add support to xenconfig for conversion of xl.cfg(5) bios config
to/from libvirt domXml <loader> config. SeaBIOS is the default
for HVM guests using upstream QEMU. ROMBIOS is the default when
using the old qemu-dm. This patch allows specifying OVMF as an
alternate firmware.

Example xl.cfg:
  bios = "ovmf"

Example domXML:
  <os>
    ...
    <loader readonly='yes' type='pflash'>/usr/lib/xen/boot/ovmf.bin</loader>
  </os>

Note that currently Xen does not support a separate nvram for
non-volatile variables.
