Return 1 if the schema entry was found optionally returning it rather

Some callers don't care which schema object belongs to the query, but
rather only want to know whether it exists. Additionally this will allow
introducing boolean queries for checking if enum values exist.

For instance, if attaching to inactive XML succeeds, @ret is

virDomainDeviceValidateAliasForHotplug() fails the control jumps
over to 'cleanup' label and zero is returned indicating success.

In cases when the hash function for a name collides with other entry
already in the hash we prepend to the bucket. This creates a 'stack
effect' on the buckets if we then iterate through the hash. Normally
this is not a problem, but in tests we want deterministic results.
Since it does not matter where we add the entry and it's usually more
probable that a different entry will be accessed next change it to
append to the end of the bucket. Luckily we already iterate throught the
bucket once thus we can easily find the last entry and just connect the
new entry after it.

If the current QEMU guest can't wake up from suspend properly,
and we are able to determine that, avoid suspending the guest
at all. To be able to determine this support, QEMU needs to
implement the 'query-current-machine' QMP call. This is reflected
by the QEMU_CAPS_QUERY_CURRENT_MACHINE cap.
If the cap is enabled, a new function qemuDomainProbeQMPCurrentMachine
is called. This is wrapper for qemuMonitorGetCurrentMachineInfo,
where the 'wakeup-suspend-support' flag is retrieved from
'query-current-machine'. If wakeupSuspendSupport is true,
proceed with the regular flow of qemuDomainPMSuspendForDuration.
The absence of QEMU_CAPS_QUERY_CURRENT_MACHINE indicates that
we're dealing with a QEMU version older than 4.0 (which implements
the required QMP API). In this case, proceed as usual with the
suspend logic of qemuDomainPMSuspendForDuration, since we can't
assume whether the guest has support or not.

QEMU commit 46ea94ca9cf ("qmp: query-current-machine with
wakeup-suspend-support") added a new QMP command called
'query-current-machine' that retrieves guest parameters that
can vary in the same machine model (e.g. ACPI support for x86 VMs
depends on the '--no-acpi' option). Currently, this API has a single
flag, 'wakeup-suspend-support', that indicates whether the guest has
the capability of waking up from suspended state.
Introduce a libvirt capability that reflects whether qemu has the
monitor command.

virCgroup struct is always defined and the free function is not calling

This fixes an issue if we try to start a VM with QEMU binary that
doesn't support QXL. The start operation will fail in
qemuProcessStartValidateVideo() which will set correct error message,
but later in one of the cleanup paths we will call
qemuDomainObjPrivateDataClear() which always calls virCgroupFree()
and that will fail on OS that doesn't support cgroups and it will
set a new error which will be eventually reported to user.
