37d51dda5d qemuxml2*test: Fix hugepages-default-system-size tests
Commit v5.10.0-269-g62065a6cb5 moved NUMA validation code to domain
definition time and appropriately adjusted affected test cases except
for hugepages-default-system-size. And since we don't mock
virGetSystemPageSizeKB in our tests, hugepages-default-system-size test
would fail on architectures (ppc64le) with default page size other than
4KiB.

4a09c143f6 virerror: Make it easier to add new error number
In v5.0.0-rc1~94 we switched from one huge switch() to an array
for translating error numbers into error messages. However, the
array is declared to have VIR_ERR_NUMBER_LAST items which makes
it impossible to spot this place by compile checking when adding
new error number.

975f2d1c90 tests: avoid re-execing test once for each mock
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.

5373f63b30 qemu: Warn of restore with managed save being risky
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.

a NULL array with zero items and the callers need to be adapted
properly.

e90a643c90 tests: avoid probing host CPU from bhyve test
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.

35d603d5ae remote_daemon: Initialize host boot time global variable
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.
