d81a27b981 qemu: Enable iTCO watchdog by disabling its noreboot pin strap
In order for the iTCO watchdog to be operational we must disable the
noreboot pin strap in qemu.  This is the default starting from 8.0
machine types, but desirable for older ones as well.  And we can safely
do that since that is not guest-visible.

1c61bd718a Support multiple watchdog devices
This is already possible with qemu, and actually already happening with
q35 machines and a specified watchdog since q35 already includes a
watchdog we do not include in the XML.  In order to express such
posibility multiple watchdogs need to be supported.

4849eb2220 remote: Propagate error from virDomainGetSecurityLabelList via RPC
The daemon side of this API has been broken ever since the API was
introduced in 2012. Instead of sending the error from
virDomainGetSecurityLabelList via RPC so that the client can see it, the
dispatcher would just send a successful reply with return value set to
-1 (and an empty array of labels). The client side would propagate this
return value so the client can see the API failed, but the original
error would be lost.

0211e430a8 remote: Initialize args variable
Recently, in v9.0.0-7-gb2034bb04c we've dropped initialization of
@args variable. The reasoning was that eventually, all members of
the variable will be set. Well, this is not correct. For
instance, in remoteConnectGetAllDomainStats() the
args.doms.doms_val pointer is set iff @ndoms != 0. However,
regardless of that, the pointer is then passed to VIR_FREE().

Worse, the whole args is passed to
xdr_remote_connect_get_all_domain_stats_args() which then calls
xdr_array, which tests the (uninitialized) pointer against NULL.

This effectively reverts b2034bb04c.

fd70335876 src/cpu: add a basic RiscV64 cpu driver
There are tests in qemuxml2argvtest that will fail if we enable RISC-V
testing, with an error like the following:

"cpuGetSubDriver:64 : this function is not supported by the connection
driver: 'riscv64' architecture is not supp orted by CPU driver"

This happens because we don't have a RISC-V driver yet.

Add a barebone RISC-V driver to allow tests to be executed. The only 2
callbacks implemented here are 'compare' and 'validateFeatures', both
acting as a no-op. More callbacks and features will be added in the
future.

50ce3463d5 qemu: hotplug: Remove legacy quirk for 'dimm' address generation
Commit b7798a07f9 (in fall of 2016) changed the way we generate aliases
for 'dimm' memory devices as the alias itself is part of the migration
stream section naming and thus must be treated as ABI.

The code added compatibility layer for VMs with memory hotplug started
with the old scheme to prevent from generating wrong aliases. The
compatibility layer broke though later when 'nvdimm' and 'pmem' devices
were introduced as it wrongly detected them as old configuration.

Now rather than attempting to fix the legacy compat layer to treat other
devices properly we'll be better off simply removing it as it's
extremely unlikely that somebody has a VM started in 2016 running with
today's libvirt and attempts to hotplug more memory.

This fixes a corner case when a user hot-adds a 'dimm' into a VM with a
'dimm' and a 'nvdimm' after restart of libvirtd and then attempts to
migrate the VM.

3d8bd1fbe3 vbox: Replace virReportError() with vboxReportError()
Now that we have vboxReportError() which reports VirtualBox
errors too, we can switch the code to use the former. And since
the vboxReportError() is designed to behave exactly like
virReportError() we can do that almost everywhere, regardless of
the source of the error.

There are a few exceptions though, for instance, when
initializing VirtualBox SDK (we don't have all the objects needed
for querying exceptions yet), or when invalid combination of
arguments was passed to an API of ours, or when a function from
other module (e.g. src/conf/) failed.

70983f4f53 vbox: Introduce vboxReportError()
When a VirtualBox API fails it produced an exception. Until now,
we did not have correct APIs wired up to get the exception and
its error message. Thus, we were left with plain:

  virReportError("virtualbox API failed, rc=%08x", rc);

This is not very user friendly because those rc values are hard
to parse (e.g. some values are defined as a sum of a base value
and some other value) and also it expects users to know where to
look.

But now that we have all machinery needed for querying
exceptions, vboxReportError() can be introduced. The aim is to
query VirtualBox exceptions and append them after the error
message we intent to report. If the exception can't be queried
successfully, this behaves exactly like virReportError().

As this is very basic operation, available to every object, it is
part of the ISupports interface among with other goodies like
AddRef() and Release().

90178989c6 vbox: Rename #include guard macro in header files
To avoid including a header file more than once, either:

  #pragma once

can be used, or the older trick (that vbox still uses):

  #ifndef MACRO
  # define MACRO

Well, vbox still uses the latter and in its 7.0 release the macro
was renamed from ___VirtualBox_CXPCOM_h to ___VirtualBox_CAPI_h.
Now, ideally, we wouldn't touch those header files for older
versions, but we need to use the same macro across all header
files (because vbox_tmpl.c includes corresponding vbox_CAPI_XXX.h
and then includes vbox_XPCOMCGlue.h which in turn includes
vbox_CAPI_v6_1.h to get the basic typedefs).

Instead of changing the newer 7.0 header file (and having to
change all subsequent versions), let's change the old ones and as
we drop support for them, we can forget this ever happened.

015a04555f vbox: Drop misleading G_GNUC_UNUSED annotation
There are few cases where a function argument is marked as
unused, but it's used later in the function. The majority of such
occurrences are in vbox_tmpl.c as a residue of older vbox
versions, but a pair was found in vbox_common.c too.

dfef0e70de network: Increase max route size when checking IPv6 forwarding
In d9ee51e, virNetDevIPCheckIPv6Forwarding was updated to walk the
contents of /proc/net/ipv6_route so that it could check to see if the
RTF_ADDRCONF was set on any IPv6 routes to ultimately determine if
enabling forwarding would result in an error due to accept_ra=1 being
set on the interface.

The implementation added in that commit limited the number of routes
that could be read from /proc/net/ipv6_route to 100_000, each with 150
characters. This is problematic for machines that have a full IPv6
routing table, as the IPv6 routing table has now grown to over 160_000
(it was closer to 100_000 at the time of that commit).

This patch increases the maximum route size from 100_000 to 1_000_000.
While a million routes is somewhat arbitrary, it's meant to be a value
that can be supported for the forseeable future. APNIC, one of the five
regional internet registries, recently published a forecast of IPv6
table growth which anticipates a worst-case growth to 1_000_000 in
January of 2029.
