libvirt currently always reports that USB is available as a bus subsystem
type when running "virsh domcapabilities". However, this is not always
true, for example the qemu-system-s390x binary normally never has support
for USB. Thus we should only report that USB is available if there is
also a USB host controller available where we can attach USB devices.

When trying to specify an input device on s390x without bus like this:
<input type='keyboard'/>
... then libvirt currently complains:
error: unsupported configuration: USB is disabled for this domain,
but USB devices are present in the domain XML
This is somewhat confusing since the user did not specify an USB
device here. Since USB is not available on s390x, we should default
to the "virtio" bus here instead.

Historically there are two places where we format authentication and
encryption for a disk. The logich which formats it for backing files was
flawed though and didn't format it at all. This worked if the image
became a backing file through the means of a snapshot but not directly.
Force formatting of the source and encryption for any non-disk case to
fix the issue.
This caused problems in many places as we use the formatter to copy the
definition. Effectively any copy lost the secret definition.

When debugging tests under GDB/valgrind there is a significant
delay each time an execve is done as they scan shared libraries
once again. For tests which use many mock libraries, we have
been invoking execve many times which makes the debug experience
horrible. This changes our framework to activate the full
set of mock libraries in one single execve.

Internal snapshots of a non-running domain do not carry any memory state
and restoring such a snapshot will not replace existing saved memory
state. This allows a scenario, where a user first suspends a domain into
managedsave, restores a non-running snapshot and then resumes the domain
from managedsave. After that, the guest system will run with its
previous memory state atop a different disk state. The most obvious
possible fallout from this is extensive file system corruption. Swap
content and RAID bitmaps might also be off.
This has been discussed[1] and fixed[2] from the end-user perspective for
virt-manager.
This patch marks the restore operation as risky at the libvirt level,
requiring the user to remove the saved memory state first or force the
operation.

bhyveargv2xmlmock calls virBhyveCapsBuild which in turn
calls virCPUProbeHost, probing the real host CPU. This
causes a test failure if the host CPU happens to contain
the 'arch-capabilities' feature as it triggers a call
to virHostCPUGetMSR() which fails on FreeBSD.
Fortunately we already have convenient code for mocking
the host CPU probing.

This is not strictly needed, but it makes sure we initialize the
@bootTime global variable. Thing is, in order to validate XATTRs
and prune those set in some previous runs of the host, a
timestamp is recorded in XATTRs. The host boot time was unique
enough so it was chosen as the timestamp value. And to avoid
querying and parsing /proc/uptime every time, the query function
does that only once and stores the boot time in a global
variable. However, the only time the query function is called is
in a child process that does lock files and changes seclabels. So
effectively, we are doing exactly what we wanted to prevent from
happening.
The fix is simple, call the virHostBootTimeInit() function which
sets the global variable.
