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.

A library has to be built with -flat_namespace to get all references to
global symbols indirected. That can also be achieved with two-level
namespace interposition but we're not using explicit symbol
interposition since it's more verbose and requires massive changes to
the mocks.

This provides a way to interpose a mock for virQEMUCapsProbeHostCPU from

Signed-off-by: NRoman Bolshakov <r.bolshakov@yadro.com>

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 syscall interface (/usr/lib/system/libsystem_kernel.dylib) has
three kinds of stat but only one of them can be used to fill

And there's no way to preload a bundle into an application. dynamic

It may happen that we leave some XATTRs behind. For instance, on
a sudden power loss, the host just shuts down without calling
restore on domain paths. This creates a problem, because when the
host starts up again, the XATTRs are there but they don't reflect
the true state and this may result in libvirt denying start of a
domain.

To solve this, save a unique timestamp (host boot time) among
with our XATTRs.
